M3x16 Socket Cap Screw & M3 Locknut Swashplate & Washout Assembly from Step 6 Lower Frame Assembly from Step 21 Following assembly, move the collective lever fore and aft to the endpoints. The swashplate and washout unit should be very smooth throughout the movement range. If not, inspect the fit of the washout guide to the pins in the rotor head, these pins can be bent slightly if binding. Also check the collective axle, the screws here may be too tight. Lastly the fit of the ball links sometimes can cause binding. These few points are the most common which will cause servo strain leading to premature wear and will appear as a jump in altitude when flying the helicopter. STEP 23 Attach the muffler to the engine with the screws provided with the muffler using threadlock. Attach the pressure tap to the top of the muffler and the M4x6 Phillips Machine screw to the bottom hole in the muffler, remember to use threadlock on these parts. Speed Torpedo Muffler CN3005HK 17 For a good seal between the muffler and the exhaust port, use a gasket made from thin aluminum, brass or use high temperature RTV engine sealant found in an automotive supply store. To properly seal the fit, after running the engine for several minutes on the first run, shut down the engine and tighten the bolts again, with the hot engine you will gain 1/4 turn on the bolts which will seal the muffler in place. STEP 24 Servo Tray (Airplane Radio) The Hawk helicopter is designed to operate with either a 4 channel airplane radio or a 5 channel helicopter radio. Step 24 shows the single collective/throttle servo location for an airplane radio whereas if you are using a helicopter radio skip to Step 25.

Also, after radio set up is complete glue the pushrod guides using a single drop of Zap Ca. One drop will stop the pushrod from binding and still be able to remove them later. STEP 34 The Tail Drive Shaft has one end flattened to engage into the main mechanics the other end needs to have a flat spot 20mm long filed on the round end of the shaft for the two 4x4mm Set Screws in the tail rotor input shaft. Thoroughly grease the tail drive shaft and insert the newly filed end into the tailboom end with the slots into the drive shaft housing assembly (ensure the end with the new flat spot exits the tailboom end with the round holes ) and degrease both ends of the shaft. 23 Put a flat spot on the the round end of the Tail Drive Shaft. 20mm Tail Drive Shaft Set [HW3063] File Tail Drive Shaft A flat file is the ideal tool for the job, alternately careful use of a Dremel Moto Tool will work. It is important that the flat be at least 1/4 of the diameter but no more than 1/3 to avoid weakening the material. STEP 35 Tail Gearbox STEP 35 M3x12 Socket Cap Attach the tail output Screw x 2 gear assembly on to the drive shaft with two 4x4mm Set Screws ( make sure the flat spot is aligned with one of the set screws ) using Tail Boom threadlock.

These are full scale drawings so you can easily match each pushrod to the page. Please note that these dimensions listed from end to end of the plastic rod-ends are to be taken as correct. Fine tuning may be required as the picture size may change when printed. Also some servos offer different horn placements for fine tuning. The numbers in the center of the pushrod drawings are the actual length of the rods to help select the correct pushrod for each control surface. Setup for the 5 Channel Helicopter radio, there will be one extra 105mm. Setup for the 4 Channel Airplane radio, requires one of the 105mm pushrods to be shorten by 12mm, 6mm per end for use as the Collective Arm Pushrod. Note: It is very important that before you install the pushrod linkages that you first charge your radio then remove all the servo horns from the servos and center all the mechanical or electronic trims on the radio. Due to printing, the overall lengths of the pushrods on the right are to be taken as correct.

Servo Setup & Adjustments In the steps 37 through 42 over the next few pages the pushrod hardware will be mounted to the servos horns and ultimately the pushrods themselves. Each step is well described but lets take a few moments to cover a few basic points on setting up individual servos. By this time the radio will have been charged overnight. Recheck that all the servo trims are centered. Each radio manufacturer makes servo horns in different shapes: round, in a cross and sometimes a star, each giving a selection of hole patterns to choose from. Choosing the correct servo horn only involves whether the particular arm or wheel has the correct hole at the 10 mm radius recommended distance measured from servo center to hole center, off by 1/2mm is ok. When using cross horns, many times the remaining arms need to be trimmed off to avoid binding on another servo like throttle and collective. When two pushrods need to be on the same horn but each at an angle, the round wheels are Futaba JR round Airtronics best suited. For wheels that are not predrilled for offsets, cross horn horn cross horn measure and drill your own holes. Remember to originally set the wheels or arms centered on the servo. What we are looking for is equal travel both in the left and right rotation of the servo, this becomes complicated by pushrods attaching to the servo at an angle. To correct this we recommend an angle for the hole location. For elevator and collective, we suggest 10-15 degrees to allow for this "linear" geometry to be set up. A range is given to make it easier for you to just choose an available angle, if this is not possible, simply lift the servo horn off the servo and press into place one "notch" back ( counter-clockwise ). We strive to have all the control surfaces setup linearly, this means that as the control stick is moved an equal distance from center that the servo will move a corresponding equal amount of travel. Although this is not clear now, this will become very clear when adjusting the throttle and collective servos movements, commonly called the throttle and pitch curves. At this time it is worth mentioning the danger of the ATV function, Adjustable Travel Volume has solved many setup problems while at the same time has created new ones. Most commonly used for throttle to easily keep the servo from binding, the thing to remember is to keep the upper and lower values should have the same. If the final values are different by more that 10 points then a mistake was made in setting the mechanical limits. Time to go back and recheck. 90˚ 10-15˚ Servo horn shown offset one notch back on the output shaft. The goal in the end after all the servos are mounted is to have the swashplate sit level or at 90 degrees to the main shaft and have the swashplate move equally fore, aft and side to side. The swashplate will also travel up and down as the collective servo is moved, it is important that in the upper position the washout hub does not contact the rotor head block while at the same time the swashplate remains above the top of the frames to avoid cyclic interferrence. Don't use the pitch gauge until you have installed all the servo horns and pushrods. Pitch settings usually are the last step in completing the basic setup for the helicopter just prior to making the first test flights. After installing the aileron and elevator pushrods, the swashplate should sit level. 28 STEP 39 Aileron & Collective Linkage ( Helicopter Radio ) STEP 39 The Aileron linkage controls the side to side tilt of the swashplate which in turn causes the helicopter to pitch to the left or right ( hence roll cyclic pitch ). Attach two steel balls with two 2mm nuts at a distance of 10-11mm from the center of the servo ( this range may vary depending on your particular radio ) and 12-15 degrees ahead of the center of the servo using threadlock. The angle offset will eliminate any stress (wear) on the servo. With the radio turned on and the trim centered, attach the servo horn and Aileron Bellcrank Pushrods (F), some slight adjustment maybe necessary to have the swashplate sit level or 90 degrees to the main shaft when viewed from front or back. Move the Aileron stick completely in both directions to insure that there is no binding in the linkages. For the Collective Servo, attach one steel ball with one 2mm nut to the servo horn at a distance of 10-12mm from the center of the servo using threadlock. With the Collective/Throttle stick on the radio in the center press the servo horn onto the collective servo so the ball is at 75-80 degrees to the servo as shown. Attach the Collective Arm Pushrod (D) and move the Collective stick completely in both directions to insure that there is no binding in the linkages. At the aileron stick is moved to the left the servo turns clockwise tilting the swashplate to the left when viewed from behind the helicopter. 1. Remove this section of the servo wheel to avoid the rod end binding against the servo wheel. 2. Optionally, the straight arm can be used however this tends to bind, for free movement use first method . As the collective stick is moved from the low position to the high position, pushrod D moves backwards as the servo turns clockwise. Aileron servo Pushrod F (2pcs) Pushrod D 10-15 Idle (-2) degree pitch. Hover (5.5) Degrees Pitch. Full collective (10) degrees pitch. 90 Collective Pitch Servo Cut this portion of the servo wheel off. Helicopter Radio Setup 29 These pitch settings will be made later with a pitch gauge. STEP 40 Aileron & Collective/Throttle Linkage (Airplane Radio) STEP 40 The Airplane setup for the Aileron servo is exactly the same as the Helicopter setup, use the same settings as in Step 34. The Collective linkage slides the swashplate up and down causing the blades to increase or decrease in pitch causing the helicopter to go up or down. For the Collective/Throttle using an Airplane radio, the two controls are made by the same servo. Install two steel balls and two 2mm nuts using threadlock at the locations shown below. The steel ball for the Collective Pushrod should be installed between 5-6 mm from the center of the servo whereas the ball for the Throttle Pushrod should be 10-15 mm. Install one steel ball and one 2mm nut on the Throttle Extension on the engine ( check to see that the carburetor is at half throttle or half way open when the arm is pointed straight up, the nut holding the arm may need to be loosened and the arm repositioned ) in the outermost hole using threadlock. Assemble the Collective Pushrod by threading the two ball-ends onto the previously shortened pushrod (105mm shortened to 93mm) to a total length of 119mm tip to tip. Move the collective/throttle stick on the radio to the center and center the trim on the radio, attach the collective/throttle servo horn to the servo so the balls are at 90 degrees to the servo and then snap on the Collective Pushrod (H) and Throttle Pushrod. Move the stick completely in both directions to insure there is no binding in the linkages. As the collective/ throttle stick is moved from the low position to the high position, the collective pushrod (H) moves backwards and the throttle pushrod (b) moves forwards as the servo turns clockwise. Aileron servo Pushrod F (2pcs) Pushrod H Hover (5) degrees pitch. Full collective (7) degrees pitch. Full power open 100% Hover-Carb open 50% Idle-Carb opening aprox. 1mm. Carb closed 10 ~15 Shut down trim full down. Full power 100% Hover 50% Idle-Trim at middle. Pushrod B Remove this section of the servo wheel to avoid the rod end binding against the servo wheel. Airplane Radio Setup 30 STEP 41-43 Rotor Head Linkages & Elevator Linkage Pushrod Ix2 Step 41 Pushrod Cx2 Pushrod Ax2 Pushrod J x 2 When attaching all pushrods, make sure same length pushrods are actually the same length from the beginning otherwise it will be difficult later to figure out where the linkage problems are coming from. The entire rotor head is set up the same way for both types of radios. Attach the two Pitch Arm to Washout pushrods (A), the two Bell Mixer to Inner Swashplate pushrods (C) and the Aileron Bellcrank Swashplate pushrods (J). Pushrod (I) was previously installed in Step 4. Pushrod G Step 42 The lower linkages (helicopter radio) are shown here to illustrate the general setup and layout of the servo linkages to the respective control surfaces. Pushrod Fx2 Pushrod D or H Pushrod E Step 43 Pushrod B The Elevator linkage is set up the same for both Helicopter and Airplane radios, the elevator pushrod controls the tilt of the swashplate forward and backward which causes the helicopter to pitch forward or backward ( hence fore-aft cyclic pitch ). Use a servo horn in the shape of a cross and trim the 3 of the 4 arms off. Install one steel ball and one 2mm nut at a distance of 10mm from the center of the servo ( mount the ball directly against the bottom of the servo arm and tighten the nut on top, trim off the screw level with the nut to avoid hitting the Aileron pushrods ), remember to use threadlock. With the radio on and the elevator trim set at the center, attach the elevator pushrod (E) to the elevator bellcrank, then attach the servo horn at an angle of 10-15 degrees behind center of the servo ( the offset enables an equal throw of the swashplate). It is important that the swashplate sit at 90 degrees to the main shaft. Note, for Airtronics servos, the ball needs to be installed on the top of the servo horn requiring the aileron servo to be moved up. This can simply be done with 1/4” thick (6mm) spacer make from wood or plastic with the appropriate holes drilled. 31 STEP 44 Elevator & Rudder Linkage ( Helicopter & Airplane radio ) Elevator Servo Pushrod E As the elevator stick is moved upwards the elevator pushrod will move backwards tilting the swashplate forewards. Install one steel ball into the servo arm from the bottom secured with one 2mm nut. Trim the excess of the screw off flush with the nut. Step 44 The Rudder linkage for the tail rotor is set up the same for both Helicopter and Airplane radios, the pushrod changes the pitch of the tail rotor blades to increase or decrease the torque compensation to rotate the nose of the helicopter about the main shaft. Use a servo horn in the shape of a cross and trim the 3 of the 4 arms off. Install one steel ball and one 2mm nut at a distance of 10mm from the center of the servo remember to use threadlock. The Rudder Pushrod (G) will at this point be installed up to the upper frames, holding the pushrod hex connector thread the short rudder pushrod and attach the ball link to the servo end. Having the radio on and the rudder trim centered press on the servo horn onto the servo set at 90 degrees to the servo and align the rudder bellcrank to 70 degrees as shown in the diagram. Rudder Servo Pushrod G The rudder pushrod has to pass through here first before it can be attached to the long pushrod and connector. As the rudder stick is to the right the rudder pushrod will move forewards increasing the thrust in the tail blades rotating the nose to the right. 32 STEP 42-43 Throttle Linkage & Main Blades Step 42 From Bag 4, attach one steel ball one 2mm nut, to both the Throttle servo horn and the Throttle Extension from Step 17 using threadlock. Position the ball at 10mm from the center of the servo and in the outermost hole on the metal throttle arm. With the radio on, and the throttle stick centered and the trim in the center, press the servo horn onto the servo so the ball is at 90 degrees to the servo ( the hovering position ). Move the throttle stick to the low/idle position and press the Throttle Pushrod (B) onto the steel balls. Check that in the low position the carburetor has about a 1mm wide opening for idling and finally as the trim is moved fully down the carburetor closes completely to shut the engine off. Also check that in the high position the carburetor is fully open. The throttle extension nut may have to be loosened and the lever repositioned to operate as recommended. 100% Full Power Hover 50% 0% Idle - Trim at Middle Full Power Open 100% Shut Down - Trim full down Hover-Carb open 50% Idle-Carb open aprox. 1mm Carb closed Throttle Servo Pushrod B Airplane Radio Setup The only change is to install the steel ball on the servo horn at a distance of 11-15mm from the center of the servo. Step 43 Main Blade Assembly The Main Rotor Blades in the Hawk kit are pre-built and balanced, the only work required is to glue the blade grip root ends to the blades ( Please note that this step is to avoid the blades separating from the helicopter during flight!!). Temporarily install the root ends ( see note ) onto the blades by cutting the covering over the holes and mark with a pencil, the outline of the plastic parts on the covering, remove the root ends and mark a second line about 3mm inside the first and trim away this internal portion of the covering with a knife. Using some sandpaper roughen the plastic root ends and glue them in place with Slo CA glue. Install the blades onto the rotor head to dry to make sure the thickness is perfect when finished. Plastic roots ends 2 per blade. HW3190 Trailing Edge (Main blade set) of Blade Cut away this portion of the covering. Sand both the plastic root ends Completed blade. Leading Edge of Blade Note: The plastic blade grips have a top and a bottom which are different when viewed from the large end. Test fit the parts to be sure that the total thickness of the blades are 14mm. 33 STEP 44-45 Canopy & Decals The Canopy has a line molded into the plastic to follow when trimming the windshield part out, be careful, trim the innermost line leaving the 6mm band for attaching the windshield. Using a sharp hobby knife carefully scribe a line several times into the plastic until you cut through the material. Similarly trim the clear windshield along the provided line, to make it easier to see the line, use a non-permanent marker and trace the line, any extra ink can be removed with rubbing alcohol. Test fit the canopy together by taping it to the canopy, some additional trimming maybe necessary to get a good fit. From Bag 5, the inside canopy mount can be installed ( note the direction of the mount ) with two 3x6mm Self Tapping Screws,( note: the location for the mount has to be moved 8mm forward of the marked location on the bottom of the canopy ). The clear windshield can be attached using six 2x6mm Self Tapping Screws in Bag 4, drill six 1mm holes at the locations shown. Step 44 To improve the adhesion of the decals to the body, peal the decal off the backing and apply one coat of spray adhesive (spray glue) to the sticky side, commonly found in your hobbyshop. For HI3067 those who would prefer to paint the canopy, we offer a complete line of colors that will bond to the plastic.

Attach the canopy using two Canopy Retaining Screws. 34 ARF Supplemental Instructions These instructions are to supplement the regular Hawk III instruction manual and to assist as some disassembly is required to install all necessary components. Open the large bags containing the landing gear, mainshaft, and inside sealed bags and the rotor head, lay out these components for easy identification. Follow the numbered steps, for those who purchased the ARF with Engine and Muffler skip over steps 16, 17, 21. Step 5, follow the instructions for installing the flybar, flybar control arms and paddles to the rotorhead. Step 11, slide the main shaft ( bottom first ) through the washout assembly, swashplate and upper main shaft ball bearing. Install the mast stopper with the smaller end towards the ball bearing and slide the main shaft down through the main gear assembly and into the lower ball bearing. Using one 3x16mm Socket Cap Screw fasten the main gear assembly to the main shaft and secure with one 3mm locknut. While pulling up on the main shaft, slide the mast stopper against upper ball bearing and insert and tighten two 4x4mm set screws ( from the sealed bag) into the mast stopper using threadlock. Step 16, follow the instructions for installing zand assembling the clutch, fan and cooling fan onto the engine. Step 17, follow the instructions for installing the engine mount and set up the carburator as specified. Step 21, before installing the engine into the mechanics the left servo frame must be removed. The cooling fan shroud has to be transferred to the engine, then the entire assembly can be bolted into the lower side frames, noting the instructions. Step 22, the washout assembly was installed in Supp.Step 11 above, follow the instructions for the rotor head. Step 23, attach the muffler to the engine, using screws provided with the muffler, note with the Century muffler no gasket is required. Simply tighten the bolts using threadlock but retighten them after running the engine for several minutes on the first flight. Step 24-25, before reattaching the servo side frame, install the collective and or throttle servo from the inside as noted. Step 33, follow regular instructions. Step 28, in order to install the rudder pushrod the tail rotor bellcrank has to be removed. Step 29, follow regular instructions. Step 35-48, follow each step as indicated to finish assembly.

For mechanical gyros: mount below the main shaft on the gyro tray Gyro Tray For piezo gyros: mount inside the canopy Install the gyro using double sided foam tape ( supplied with gyro ) put a full strip along the bottom of the gyro unit and press onto the surface. For a good bond make sure both surfaces are clean and dry. For further installation of the PG-01T gyro, see the next page. Mechanical Gyro Foam tape Note: the gyro tray in the behind the engine is for mounting the mechanical style gyro, not for the piezo type. Receiver, Battery Pack and Gyro Controller Using the foam rubber, wrap the battery pack, receiver and gyro controller(mechanical type) separately, allowing wires to be collected and tied together. Using two elastics looped through the front of the top servo tray, secure the components to the two hooks on the lower servo tray. Depending on your equipment, the gyro controller and switch can be mounted on the provided bracket. Balancing the Rotor Head & Attaching Main Blades Balance is the most important part in maintaining a safe and reliable helicopter. First check the blades for balance, this can be done on a balancer but can be done directly on the helicopter by tipping the helicopter on its side at the edge of a table and attaching the blades with two 4x30mm Socket Head Cap Screws and 4mm locknuts. Temporarily remove the bolt to secure the autorotation bearing so the head spins free ( remember to replace this bolt!! ). If one blade stops at the same spot add some tape to the lighter blade to balance the rotorhead. The same procedure can be used to balance the flybar without the main blades attached. Distance B Distance A Flat Table Surface Bolt the blades together and support by the ends of the bolt off a flat surface. If one blade tips to one side add small pieces of tracking tape until both blades hang an equal distance from the table (Distance A = B). Attach the Main Blades to the helicopter using two 4x30mm Socket Head Cap Screws and M4 Locknuts. M4x30CS Machine Screws x 2 M4 Locknuts x 2 When attaching the main blades, the direction of rotation is clockwise, when looking on top of the helicopter. **Blade Bolt tension on main blades should be set by starting from loose blades, tighten the bolts a little at a time until the blades will hold straight as the helicopter is tipped on its side. Slightly tighter is good. Too tight and a vibration will occur, too loose and a boom strike can happen. Tail blades can be set the same way. 36 Setup and Installation of PG-01T Gyro (purchased separately) Installation 1. First of all, please connect the rudder servo to your receiver. Turn on the transmitter and receiver. It is particularly important that the rudder trim (mechanical and electronic) are set to the neutral position and the servo horn is installed in the neutral position on the helicopter. Recheck the neutral position again as this a vital point in the correct calibration of the PG-01T unit. Otherwise, it can cause setting changes later. 3-pin male connector 2. Turn your transmitter and receiver’s power off. Disconnect To receiver the rudder servo from the Receiver and connect the wiring harness. The harness has a 6-pin male plug at one end and a 3-pin female plug and a 3-pin male plug on the other end. + Pos - Neg Signal Power LED To high speed rudder servo. To receiver. Warning, if any radio system is used other than JR or Futaba make sure same polarity is mantained otherwise you will damage the PG-01T. 3. 6-pin male connector To Gyro Note: upper plug is connected to the rudder servo, the lower plug goes to the receiver. 3-pin female connector - To high speed rudder servo. Mount PG-01T using one layer of 1/4" soft double-sided adhesive tape to absorb the vibration which is caused by the engine and mechanical set-up (two are supplied). Most helicopter kits have a recommended location for the gyro, this location is for mechanical gyros. This does not apply to the PG-01T piezo gyro. Mount the PG-01T inside the canopy to keep the gyro clean and is subjected to less engine vibration. The gyro should be mounted so the case of the gyro does not contact the helicopter frame or other radio components or wiring. Setup & Adjustment 4. Turn on your transmitter and receiver, the red Power LED remain on while the PG-01T is working 5. Check that the gyro is installed correctly by watching the rudder servo. While holding the rotor head move the rudder stick to the right and observe the direction the servo arm moves. Now quickly rotate the nose to the left, the servo horn should move in the same direction. If the rudder servo horn moves in the opposite direction reverse the gyro direction. Using a small flat screw driver change the switch direction on the gyro. The PG-01T neutral adjustment is factory set however check that after the radio is turned on with the gyro connected, the rudder servo is still at the exact same neutral setting as observed in Step 1. If the this neutral setting has changed, using a plastic screw driver adjust the NEUTRAL trim pot to return the rudder servo horn to the neutral position. Turn the GAIN trim pot Clock-wise to the right at 100%. This will change the neutral position, tune the NEUTRAL trim pot slightly to return the servo to the neutral position. Return the GAIN trim pot to 50%. After the above adjustment, we would like to suggest you to put on a sticker to cover the NEUTRAL trim pot as no further adjustment is required. The tail rotor pitch settings should be setup so the tail should have no tendency to rotate when hovering. Do not make radio trim adjustments but shorten or lengthen the tail rotor pushrod. The initial GAIN setting should be 30-50%, bring the helicopter to a hover, keep increasing the GAIN until the tail starts to oscillate (hunt). At this point reduce the GAIN slightly (5-10%). Gain Trim Pot 6. 7. 8. A. If hunting occurs at less than 65% in hover - then move the rudder pushrod connection one hole inwards on the servo. B. If no hunting occurs at 100% in hover - move the rudder pushrod connection one hole outward on the servo. 0% Gain 9. Adjustment of Gain. BEGINNER EXPERT FLIER PG-0lT 30% - 80% 30% - 60% Neutral N R Neutral Trim Pot N -50% Gyro direction 37 100% +50% Final Adjustments - Radio Setup Now that the servo installation into the helicopter is finished the following pages should be reviewed. As various types of radios can be used to setup the helicopter, some of the following information may not apply. Servo Direction (Servo Reversing) Pitch & Throttle Curve Adjustments Check that all servos move in the correct directions, see the diagram on pg 36. The ultimate goal for adjusting the curves on your helicopter is to reduce how much the tail rotor moves during flight and aerobatics. This leads to maintaining a consistent main rotor RPM which can only be achieved through adjusting the individual values which control the pitch and throttle at a given stick position. Dual Rates For beginners ( using the flybar weights ) the dual rate values should be set at 100% for both switch positions until hovering has been mastered. Normal position: Switch position 1: (high rate) 100% (low rate) 75% Exponential The exponential function allows adjustment of how sensitive the cyclic controls are when the machine is hovering. This should be left at 0% (linear) until all trimming is complete. Pitch Curve Adjustment The following chart shows the values for the collective pitch measured in degrees which are made on the helicopter using a pitch gauge. The Travel Adjustment function (if available makes these settings easy). For the beginner it is recommended to set the low stick position to 0 degrees to avoid damaging the helicopter while reducing the power during the first few flights. These settings will need slight adjustment to keep the helicopter at a consistent height at mid stick. Pitch Curve Values Flight Setup Method Mode Sub Trims The sub trims on the outside of your transmitter are used to fine tune the servo center positions while testing or in-flight. If the trim has to be moved more than 2-3 divisions then readjust the linkage length to set the trim back in the center. N N 1 2 H Beginner Hovering Stunt & Aerobatics 3D** Autorotation Low Pitch (low stick) 0 -2 -5 -7 -5 Hovering (mid stick) 5 5 5 0 5 High Pitch (high stick) 9 9 8 10 12 ( N - Normal flight mode, 1 - Stunt mode one, 2 - Stunt mode two, H - Throttle hold-autorotation ) Note** In order to avoid binding at high pitch angles the flybar control arms need to be reset at an angle of 10-15 degrees down from parallel. Travel Adjustment ( endpoints ) Using endpoints to adjust to the limits of how far the servo is allowed to move is very convenient for fast set-up. If binding occurs simply reduce the travel in that direction. ** Note: by changing one side only (high or low stick) the servo travel is no longer linear which will tend to make that control surface unstable. It is better to set the high/low adjustments the same, or make actual pushrod adjustments. 38 Pitch Curve Hovering - ( linear ) Normal Flight Mode 5 Pitch Range 10 9 Throttle Curve Adjustments After several tanks of fuel the engine will be run-in, at this time you can modify throttle settings but remember that the smoother the engine the less adjustment required. Not all engine / muffler / fuel combinations are the same which will shift some of the values shown below. -2 -5 Mid High Stick Position Throttle Curve Aerobatic Flying - Flight Mode 1 10 9 Hovering - ( linear ) Normal Flight Mode Autorotation Pitch Range 100% 50% Power Output Low 10% -5 0% Idle High Low Stick Position Mid High Stick Position Aerobatic Flying - Flight Mode 1 3D Flying - Flight Mode 2 100% 0 Pitch Range 10 50% 40% 0% Idle -7 Low Mid Low High Mid High Stick Position Stick Position Autorotation - Throttle Hold 3D Flying - Flight Mode 2 12 100% Pitch Range 5 50% -5 Low Mid Stick Position 39 Power Output Mid High Power Output Low 0% Idle Low Mid Stick Position High Tail Rotor Setup What separates airplane radio equipment from the helicopter version is in the control of the individual curves discussed earlier and in the Revo-mixing. Take a moment to consider the helicopter hovering in front of you. 1 Nose rotates left at hover. Problem: Not enough pitch in tail rotor to match torque setting of engine. Action: Increase pitch by shortening the rudder pushrod. Pilot 2 Nose rotates right at hover. Problem: Too much pitch in tail rotor to match torque setting of engine. Action: Decrease pitch by lengthening the rudder pushrod. Pilot Once the tail rudder pushrod is adjusted correctly so the tail does not rotate ( don't consider wind now ) the revolution mixing can be adjusted. Revolution Mixing The revolution mixing function allows the helicopter to climb or descend without the tail rotating. There is a high & low setting on the helicopter radio. The values shown will vary depending on engine, blade pitch and fuel but provide a starting point for the beginner. For each flight mode setting, there will be different Revo-mixing amounts. For forward flight the settings will be lower than hovering due to the aerodynamic forces effecting the helicopter. Here is a starting point for revo values: High Stick Setting: 40 Low Stick Setting: 20 Normal Flight Mode These values correspond to the total travel for the tail rotor pitch. To adjust the high setting, hold the helicopter at hover and increase the throttle so the helicopter climbs steadily. Notice the direction the nose rotates: Nose rotates High & Low left increase revo value to increase tail pitch. right decrease revo value to decrease tail pitch. To adjust the low setting, start from a high hover and decrease the throttle to descend, notice which direction the helicopter rotates. Gyro Gain Adjustment The gyro assists in holding the tail rotor, actually compensating for changes in wind direction or quick movements. First check that the gyro is installed correctly by watching the rudder servo. While holding the rotor head move the rudder stick to the right and observe the direction the servo arm moves. Now quickly rotate the nose to the left, the servo horn should move in the same direction. If the rudder servo horn moves in the opposite direction reverse the gyro direction. Generally the starting setting for the gyro gain is 60%, keep increasing the gain setting until the tail starts oscillating back and forth, then reduce the setting slightly. Problem: Tail rotor makes sudden uncontrolled rotations. Solution: The gyro direction is possibly set in the wrong direction. 40 Before Flying your Hawk 30 Helicopter Before each flight, check that all bolts and screws are tight. Simply flying your helicopter, will loosen any screws which are not threadlocked or secured with a lock nut. First Flights For the beginner pilot, a training pod is strongly recommended to assist in learining to hover the helicopter with substantially reduced risk of crashing. These systems provide an on ground training capability to allow pilots to become familiar with the helicopter before actually leaving the ground. Starting Your Engine If the Engine Does Not Start Fuel 15-30% Helicopter fuel is recommended containing more oil. Use a fuel filter between the fuel gallon and the heli to remove any dirt that could stall the engine. Fuel the helicopter by removing the fuel line from the carburator and replace when finished. Q. The engine does not turn easily with the starter. A. The starter battery may be too weak or the engine is flooded. For flooding, remove the glow plug and turn the engine over several times to clear the combustion chamber of fuel and retry. Needle Valve Following the engine manufacturers instructions, turn the main needle valve until closed and open to the setting the instructions call for. Different engines will have different settings. Radio Always turn the transmitter on first, then the helicopter & gyro and reverse when finished, turn off the heli & gyro first then the transmitter. If the radio acts erratically or intermittent, find the problem before starting the engine. Glow Plugs Using a glow plug connector, remove the canopy or optionally use a remote glow plug connector to heat the glow plug. Warning!! glow plugs operate at 1.5V not 12V. Engine Before starting the engine, check the correct direction of rotation and make sure the electric starter is turning the same direction. Starting Start the engine from low throttle with the trim centered. Holding the rotor head in one hand, angle the starter and press down slightly to engage the starting shaft into the fan. Start the electric starter until the engine starts. If the engine does not start recheck all previous points. The main blades will not turn until the engine RPM is above idle. Stopping To stop the engine, with the throttle stick in the low position, move the trim all the way to the low position. 41 Q. The engine rotates and tries to start but doesn't. A. The glow plug may be getting old. The glow plug batteries are weak. The starter may be turning the wrong direction. Q. The engine just does not start. A. The glow plug may be burned out. Fuel may not be getting to the engine, check for a clogged fuel line, dirt in the carburator or the main needle needs to be opened out slightly. Q. The engine starts but immediately stops. A. There is a clog in the fuel line, the carburator is not open enough at idle- open the throttle trim by 1-2 clicks. Helicopter engines have a low speed needle which is factury set, beginners should not adjust it!! Adjusting the Blade Tracking Pitch In steps 34-35 you setup the pitch range using a pitch gauge and setting the pushrods on the servo horms at specific distances. Once the helicopter is flying the pitch setting have to be fine tuned. Using appropriate training gear, increase the throttle until just before the helicopter lifts off and sight the rotor disk from 15' back. If there appears to be 2 rotor disks then adjust Pushrod C until only one disk appears. Using colored tape mark one blade so you can adjust the correct blade. Starting the engine for the first time. The model engine is the single most difficult part of model helicopters to the beginner, second only to learning to fly. For this reason we have taken the time to go through starting the engine the first time with you to help you to understand the basic operation and tuning of the engine. Items to recheck: 1) Servo direction for the throttle channel. Turn on the transmitter switch, then the switch on the helicopter, move the throttle/collective stick to the low position, the carburetor arm should look exactly like the diagram (1a). Watch the throttle servo. As you raise (increase) the left stick the throttle pushrod will move towards the front of the helicopter, all carburetors work the same, as the throttle arm is rotated by the throttle pushrod, the barrel of the carburetor rotates counter-clockwise as it opens. If this does not happen you need to reverse the servo direction and reset the throttle arm in Step 17. Starting the engine at full power will possibly damage the engine and will damaged clutch components on the helicopter. (1a) 2) Fueling the engine. Open the gallon of fuel and insert draw line from the fuel pump into the fuel, remove the fuel line at the carburetor inlet and connect to the fueling line of the fuel pump. Fill the tank until you start to see bubbles moving in the pressure line to the muffler. Reverse the pump for 1 second and disconnect the lines starting with the fueling line and reconnect to the carburetor. Recap the fuel to keep moisture out. Only fuel the model when you are setup and actually ready to start the engine, it is common for the carburetor to fill with fuel while sitting on the bench over a brief period of time. More common is the engine flooding while trying to start. This the case as you are starting with an electric starter the engine initially turns easily but soon slows down. 3) Last pre-flight checks. Make sure that both the radio Tx and Rx have been charged overnight and the glow starter (if rechargeable). Do a range check, walk away from your helicopter with the antenna fully collapsed to 30 paces and have someone verify that all control surfaces are operating. If you do not make this distance have an experienced modeler check over your setup, do not fly until then. 4) Cranking the engine over. When a brand new engine does not start there are only three major possibilities: a) the glow plug is not hot enough or already burned out or b) fuel is not getting to the carburetor or c) too much fuel is entering the carburetor. This is assuming you have gone through step 1 in this page. Connect the starter to a 12Volt source and verify that the starter will turn the starting cone counter-clockwise. Connect the glow starter connector to a 1.5Volt source or use a rechargeable glow starter. Do not connect yet. • Move the throttle stick to the low position with the trim in the center. • Look at the fuel line entering the carburetor, is there fuel in the line, if not pull the fuel line off and check. • If there is no fuel in the line, reconnect and push down on the start cone and turn the engine by hand until you see fuel entering the carb. make one more revolution. Putting a finger over the exhaust hole will help. • Connect the glow starter to the glow plug, place one hand firmly on the rotor head, absolutely at all times keep your hand on the rotor head, should the engine start anywhere above idle you will only have a few seconds to put the starter down and pull the fuel line off the carburetor line going to the engine. It is a good idea to make sure you are standing/kneeling on the fuel line side. • Place the starter on the starting cone and push down, before you start, rotate the cone with the engine engaged backwards (clock wise) until you feel the compression increase. • Press the button on the electric starter, there will be an initial popping sound as the engine turns over and within a few seconds the engine should start. If it does, while holding the rotor head put down the electric starter and move the throttle trim down until the engine continues to run at the lowest speed without quitting. If the engine starts to die simply move the trim up one or two clicks. Do not move the throttle stick from the low position. 5) The engine does not start. Do not continue to crank the engine over if it does not start. a) Remove and check the glow plug, is the glow plug dry or wet? Connect to the glow starter or the glow connector and verify that the element glows a bright orange to a white color, if you get an orange glow then your glow starter is not supplying enough power to the glow plug. b) If the glow plug is wet, then the engine is receiving fuel. If the glow plug is dry, no fuel is reaching the engine. Try re-priming the engine, point #3 step 4. Again verify that the engine is receiving fuel. c) Is the engine very difficult to turn over, to the point that the electric starter is unable to turn the cone? If yes, you have successfully filled the engine and carburetor with fuel, do not force the starter as you can damage the starter and prematurely wear out the starting cone and ultimately the starting shaft will fail. First, disconnect the glow starter and pickup the helicopter and tip forwards and backwards with the muffler side down. This will drain the muffler of raw fuel. Next turn the cone until the half past the highest compression point, here the exhaust port will open and again drain through the muffler. Try to start again. Same problem, remove the glow plug and spin the engine (without) plug and any excess fuel will be expelled, replace glow plug and try again. If the engine still doesn’t start, contact an experience modeler to help you with starting the engine, the problem maybe very simple. 42 Basic Hovering Hovering When all is set, ready and checked, attach your training gear/pod and start the engine. (1) Place the helicopter pointing into the wind and stand behind the model about 15' away. (2) Always watch the nose of the helicopter, move the rudder left and the nose will move left. (3) Start by increasing the throttle slowly until the helicopter rises 2-6 inches off the ground then set it back down. (4) Repeat this process until you become comfortable with the holding the model in the same spot for a few seconds then land it. After some time at this you can increase the height slightly up to 1 foot ( be very carefull not to get too high ) as you are practising taking off and landing. This is the most basic but required skill for the beginner to learn. Beyond Hovering It cannot be stressed enough that mastering the hovering skill is crucial to becoming a good helicopter pilot. As you progress in your learning, always practise hovering until you are completely comfortable in holding the helicopter in any direction at any altitude. Perfecting hovering enables you to learn all the types and styles of helicopter flying, forward flight, loops and rolls, 3D (aerobatic flying) and anything you want to do with your Hawk helicopter as it can be set up for beginner through to expert. Lastly, have fun!! Pre-Flight Checklist 1. 2. 3. 4. 5. After turning radio on, move each servo separately, looking for unusual or excessive movement. Lubricate the main shaft above the swashplate and the pitch slider on the tail output shaft with oil. Inspect the main and tail rotor grips for play or binding. Turn the main gear in both directions to feel if a problem is developing in the drive train. Check the glow plug and fuel lines for signs of wear. PRE-FLIGHT CHECK UP & TRIM ADJUSTMENTS All trim adjustments are to allow you to lift the helicopter straight up and can be made one click or detent at a time on the radio. 1 DOWN (1) Collective & Throttle: Slowly raise the throttle stick, the helicopter should lift off at half stick. If it tends not to lift off increase the hover pitch on the radio or increase the throttle trim. If the helicopter lifts off before mid stick decrease these settings. (2) Rudder: When the helicopter is ready to take off, make a correction trim first then use the rudder stick to control the Left & Right. Note, now is a good time to make a final adjustment on the gyro, see gyro manual. (3) Elevator: If at hover the helicopter tends to move forward, move the trim down, if it moves backward move the trim upwards Use the elevator stick to control the Forward & Backward. (4) Roll (Aileron): If at hover the helicopter tends to move left, move the trim right, if the helicopter moves to the right move the trim left.
