R/C Helicopter Safety

A model helicopter must be built exactly in accordance with the assembly instructions. Compass Model Ltd. has spent much time and efforts refining this product to make it reliable in operation and easy to build. Vibration and stress levels are high and all fasteners and attachments must be secure for safe operation. Safe operation is the responsibility of the builder/flyer and starts with careful construction and continues with selection and installation of reliable radio equipment and motor/engine.

The need for safety is nowhere greater than at the flying field. A number of guidelines for safe flight have been developed by experienced flyers and are set down here. It is urged that they be read, understood and followed.

Attention:

each country has its own security application which cannot be laid down here so prior to any flight request the rules to apply in your country/Flying field.

Attention Atom 7HV Limitations :

Atom 7HV Max. rotor head rpm: 2100 U/min

Atom 7HV Max. collective pitch range: +/- 12°

Guidelines for Safe R/C Helicopter Flight

• Fly only at approved flying fields and obey field regulations.

• Follow frequency control procedures. Interference can be dangerous to all.

• Obtain assistance from experienced pilots.

• The Guidance provided by experienced pilots is valuable and sometimes necessary.

• Know your radio. Check all transmitter functions before each flight.

• Be aware that rotating blades are very dangerous and can cause serious injury or even death.

• Never fly near or above spectators other modelers or animals.

• Do not fly r/c helicopter models near buildings, high voltage cables, trees or other obstacles.

• If you are a beginner, get help trimming and adjusting the model before you start the flight training.

• Don’t “track” the main blades by holding the tail boom. This is a temptation to builders who cannot hover yet and is very dangerous.

• Follow all recommended maintenance procedures for model, radio and motor.

• Only turn off the radio after the brushless motor is disconnected.

Pre-assembly Information

When first opening your Atom kit, you will notice that all of the parts are packaged and numbered to coordinate with the assembly step numbers of this instruction manual. All small hardware (nuts, bolts, washers, etc.) for each step are packaged separately within the main parts bags. When beginning a section, you will need to open only the bag with the corresponding number to the section you are about to start. It is suggested that you place all of the hardware in an open container (e.g., servo case) during assembly so as not to lose any of the small parts. It may also be helpful to familiarize yourself with the various sizes of screws, bolts, nuts, etc., as illustrated in the appropriate assembly section before you begin assembly. In most cases, at the end of each assembly section, there should be no parts remaining. Great care has been taken in filling the bags with the correct quantity of parts and hardware for each section. However, occasional mistakes happen. In the event that you find a parts shortage or are in need of technical assistance, please contact your local Compass Model parts dealer.

The Servo installation is done without the supplied Servo Rubbers. If you want to use the Rubber, please use

M2.5x12 Bolts, instead of M2.5x10.

For mounting the swashplate servos to the bearing blocks, tighten all bolts of the upper bearing block with medium threadlock. Fix the servos at the upper bearing block. Install the main shaft through all bearing blocks and push the middle bearing block up against the bottom of the cyclic servos. Tighten the four screws in the X-shaped parts that secure the middle bearing block. Now slide the main shaft up and down to make sure the bearing blocks are all aligned. If the main shaft doesn't slide freely, loosen the screws of the bearing blocks and tight them in a cross pattern. The bearing blocks must be aligned parallel to each other. You can control this by comparing the height of the bearing block in the long holes of the side frame. Do not forget to apply new threadlock when loosened a screw!

Use these long holes to adjust the middle bearing block to fit different servos.

Remove the black cap of the canopy standoff to loosen and tighten the screw for adjusting the bearing block.

To pull the belt through the tail boom, slide a cord through the boom and fix the belt very carefully at the cord. You can also use a strand and bend a hook at one of the ends.

Crimping the belt damages the tensile cords and will result in premature failure!

Use medium Threadlock on all screws going into metal parts

Slide the tail case completely onto the boom, align it to the Compass writing and fix it with the clamp on the rear side. The two locking bolts ( 8 )must be screwed completely into the case to pierce the boom. After this step, the angle of the writing can not be adjusted any more!

Tip

: Do not tighten the bolt of the belt idler pulley yet, it will be adjusted later.

6

Tip

: You can use a very small drop of thin

CA glue to secure the pin in the tail pulley.

Motor And Drive Tips

Use medium threadlock on all screws going into metal parts

Gear backlash adjustment:

For smooth operation and performance, it is necessary to adjust the gear backlash properly. Excess gear backlash can cause premature gear wear and damage. Insufficient gear backlash can cause vibration, as well as overheating of the Motor and speed controller. Adjust the gear backlash by placing one piece of paper between the gears to set the distance. When the bolts are secure, remove the paper and test the gear backlash to insure that there is a slight amount of free movement between the gears.

To adjust the correct backlash between the motor pinion and the main gear loose the 4 motor mount bolts on each side , then fix them tightly with threadlock.

Tip

: Use a pressure resistant extra sticky grease on the maingear to reduce abrasive wear and noise. Grease it every five flights for the first 20 flights. Check the gear backlash especially in the first 20 flights. Apply some grease when you recognize that the main gear gets „dry“.

Tip

: Choose a low kv motor so you can use 14t or higher pinion for good contact with the main gear to prevent excessive wear on the main gear.

Motor Setup And Maintenance Tips

: Use at least 5.5mm gold connectors with an even surface for your motor wires and ESC wires. Use heat shrink and look for a good isolation. Check all wires and connectors regularly for good fitting and damage. Damaged wires and connectors can cause severe damage to your model and equipment! Oil the motor bearings each 10 flights and change them if they make strange noises or when the motor gets clearance at the shaft or bell.

Soldering Tips

: Use a soldering iron with atleast 80W and SN60PB40 brazing-solder. The temperature should be around 380°C. Use a non-conductive heat resistant surface and clamps or pliers to hold the connectors and wires. Do not heat the connectors and wires to long. The braze point must be shiny and even. If you have problems with the soldering, ask a experienced modeler for help. Due to extreme high currents of up to 200 Amps and mechanical stress to the connections, good soldering points are very important to guarantee a safe function of your power system.

Use blue threadlock on all screws going into metal parts.

swing range

Tip

: If the rubber gets older, you can increase the tension by opening the two screws in the holder and sliding it to the rear in the long holes.

Tip

: Check the rubber from time to time for cracks and refractory material.

Adjusting the belt tensioner is pretty easy. Just remove the rubber ring and adjust the tension as usual. After remounting the band, the tensioner should swing in 1/3 of his possible travel– if it swings more in then the tension is to lose.

Increase it by removing the band again and move the tail boom further to the rear. Use the four screws in the tail boom mount to fix the boom.

Check the belt tension sometimes.

Readjustments may be needed after a while or big temperature differences.

Tip

: Fix the tail boom clamp later, so you can adjust the angle for a perfect smooth running tail control.

Adjust the belt idler pulley with a distance of

0.2-0.3mm to the tightened belt. Do not over tighten the screw as it may result in a bent tail case and sluggish bearings.

Linkage Length & Setup

Do not apply plier to resize Ball Links. Pliers could cause hidden damage to Ball Links and result in failure when operation.

Use medium threadlock on all screws going into metal parts and nuts.

Do not use pliers or screwdrivers to screw the ball links onto the linkages.

It can damage the ball links and result in failure. Screw them on by hand or use special tools.

10 20 30 40

Compass Model ball links are build up on the tight side. This allows you to adjust them to your personal needs. Use a ball link sizing tool to adjust the ball links. Clip the ball link on the corresponding ball where it will be later and test if it moves freely. If not, clip it on the ball link sizing tool and rotate it a few turns in different angles. Test it again on the ball. When you level the whole linkage horizontally, the linkage should almost flip downwards by ist own weight. Do the resizing in small steps and test the fitting every time. If any ball link has clearance on the ball, change it and do not use it again.

All ball links must be clipped on the balls with the Compass writing facing to the outside.

Tip:

You can make your own ball link sizing tool. Just use a Dremel with a thin cutting wheel to cut two slots opposite to each other into a ball you don´t need. Stick a screw through the ball and screw a nut on the other side to fix the ball. You can clip ball links onto this tool and use it as described above.

Check all ball links for clearance and damages everytime you go flying and change worn ball links early.

The length of the plastic drive tube can be changed easily by turning the ball link in and out.

Linkage Lengths:

Servo Horn to Servo center: about 17.5mm

Servo to Swash: about 57mm inner edge to inner edge

Swash to A connector: 58mm inner edge to inner edge as per picture.

Tail Setup

90°

At zero position, the servo arm should be at 90°. Use the best fitting servo arm and read the manual of your FBL-

Unit how to adjust the servo midposition.

Adjust the linkage length so that the slider is parelel to the tail case side wall.

It is important to limit the servo travel to the endpoints of the slider shown below. Too much travel can cause a stall and lead to a loss of tail authority.

To adjust the gyro direction, read the manual of your fbl unit. Look at the heli from behind.

When you turn the nose to the left (counter clockwise), the tail pitch slider must go towards the tail rotor hub and away from the tail case.

When you turn the nose to the right (clockwise), the tail pitch slider must move towards the tail case and the bearing.

Doule check this step!

Wiring Tips

Never use RC-components with damaged wires. Check all wires for damaged isolation and breakage. Control all servo connectors for a tight fit and be sure no wire is loose in the connector.

All wires must be protected against damage through sharp edges of the carbon frame and metal parts. Zip ties can also cause damage to the wires.

Tip:

Cut open a piece of fuel line to cover sharp edges.

You can also use fuel lines to cover zip ties to prevent them from damaging the wires.

Carbon fibre and metal parts are conductive . Open wires, contacts and open gaps between two contacts touching the frame can cause a short curcuit and damage to the RC-Equipment.

the RC-Equipment.

Tip:

The best way to protect your wires is to use braiding sleeve such as those used for computer wiring or casemodding. Seal the ends of the sleeve with heat shrink to prevent them from unraveling. You can also you use heat shrink to protect wires where zip ties overlie.

Keep all wires as short as possible. Avoid unnecessary extensions and connections, but use extensions if a wire is almost to short to avoid mechanical tension in the wiring. Never tighten a wire to much. Be sure that nothing pulls at a wire. It is very important to have zero tension between wires, plugs and RC-Components.

Do not pull out connectors by pulling at the wires!

Do not fold any wire, place them in curves.

Keep all wires away from rotating parts, linkages and servo arms.

Tip:

Use a plier to bend zip ties before you use them. It wil be easier to get them around a corner.

Tip:

Secure connectors with heat glue at the receiver and

FBL-Unit. Avoid contact of the glue with stickers and the wires. The glue is easy to remove.

Be careful when heating heatshrink on wires, don´t heat it up to long or with to much heat or it may damage the isolation.

Control all wires and connections regularly to discover hidden damages and defective contacts early. Never go flying if any failure occurs!

FBL Setup Tips

Please read the manual for the current software version of your FBL-Unit carefully and follow all instructions. We can't give you any specific tips because most brands of FBL-Units change their software from time to time and your setup depends on many other factors like used blades and servos. Please check our website to find some setups from our Teampilots.

Tip:

For easy measurement of the pitch angles during the setup, please use something long and straight (like a flybar or CF-Tube) and put it on the upper servo mount behind the servorods.

With this trick you can easily use the pitchgauge to check the collective and cyclic angles.

Tip:

All servo horns must be at 90° (horizontally). Try all possible positions of the servo horn to get as close as possible to 90° at neutral servo position. Keep all swashplate linkages at exactly the same length. Level the swashplate horizontally in all directions, therefore read the manual of your FBL-Unit and follow the instructions!

If you have vibrations it is better to find the source than using a softer tape. All wiring to the FBL-Unit must be done without tension and not to stiff. If you use some kind of cover to protect the wires, please remove it on the last 3-5cm to make sure that vibrations can’t be carried to the unit – which will cause strange behaviour like unwanted movements of the helicopter.

Remove all kind of grease and oil from the radio tray and the bottom of the FBL-Unit with alcohol or something similar.

Please place your FBL-Unit extremely carefully in your helicopter. It is important that the unit is in a perfect 90° angle to all axes to get best performance. A wrong mounted unit can cause a wobble during piro-manouvers.

A perfect CG (Center of Gravity) is very important to get a perfect flying model. The CG must be exactly under the mainshaft. Adjust the CG by positioning the battery to the front or to the rear on the battery tray. You can also change the position of the battery tray with the three mounting holes in the side frames. The CG should be measured with all parts including the canopy.

Tip:

There are two methods to find out where the CG is. The first method is to hold the model under the main blade grips and look if it tilts forwards or backwards.

You can also hold the model at the main blade grips and fixed main rotor blades with the main shaft leveled horizontally. Look with the canopy facing to the right and then facing to the left (due to the free wheel) if the nose or tail tilts down.

If the nose tilts down, you have to put the battery more to the rear, do the opposite when the tail tilts downwards.

FBL Setup Tips 2

Look at the helicopter from the side to test the

elevator

gyro direction.

Double check the gyro directions of your fbl unit!

Incorrect gyro directions will cause a crash!

Checking the swasplate and tail gyro directions is a part of the preflight check!

Tilt the helicopter forwards as shown in the picture. The swashplate must tilt backwards.

Tilt the helicopter backwards as shown in the picture. The swashplate must tilt forwards.

Watch the helicopter from the front/canopy to test the

aileron

gyro direction.

Tilt the helicopter to the left, the swashplate must tilt to the right as shown in the picture.

Tilt the helicopter to the right, the swashplate must tilt to the left as shown in the picture.

Grounding

Belt-driven tailrotors can produce a high amount of electricity.

The discharge can cause a blockage of the radio signal and the

RC-Components. If you have transmission problems and/or problems like hard tail kicks and lockouts during flight, you have to ground the tail. We recommend to ground each helicopter for safety reasons if you are not sure if everything works without failures.

To ground the helicopter, use a piece of fine sandpaper to remove a little bit of the black anodizing between the two tail boom clamps in the frame with care. Do not modify the tailboom behind the tail boom clamps! Use a piece of silicon wire with a diameter of at least 1mm² and skin one end. Attach the open end to the tail boom with one or two zip ties. Lay the wire to the motor, skin the other end and attach the wire to one motor screw by jamming the open end under the screw.

10

20

30

40

Do not use a file, rasp, knife or coarse sandpaper to remove the anodizing. Deep scratches will damage the structure of the tail boom and can cause a breakage of the tail boom!

11

Rotor Direction & Blades

10 20 30 40

When the main rotor spins clockwise the tail blades should turn clockwise as well watching the tail rotor from the tail fin side. If not, the belt is twisted and has to be corrected.

Be sure that the main rotor and tail rotor blades are installed in the right direction. The leading edge has to show into the rotor directions.

Do not overtighten the blades. The main rotor blades should not be able to retract when you hold the helicopter sideways with the mainshaft and both blades horizontally. Do not thighten the blades much stronger than this and use the washers delivered with the blades.

Do not grind the blades if they don´t fit. Ask the manufacturer for other washers.

Use the same amount of washers with the same thickness over and under the blades!

The get a helicopter without vibration issues and, perfect flight abilities and low power consumption, you have to track the main rotor blades. The first step is to have identical lengths from the end of the ball link on the plastic drive tube to the metal arm.

In most cases, the blade tracking will be fine after doing this. To check it during the flight, get the help of an other pilot for safety reasons. Get in a hover and ask him to watch the rotor disk. Both blades must be in one line. If there are two disks or the blades appear thicker than they are, you have to readjust the blade tracking by turning in and out the ball links in the plastic drive tubes. Mark one blade or blade grip and turn in or turn out the ball link of this blade by one turn. Remember the direction. Hover the helicopter again, if it gets worse, turn back the ball link and rotate it one turn in. If it get´s better but is not perfect, turn the ball link of the other blade out by one turn and hover again. The blade tracking should be perfect now. If not, an issue with the rotor blades is likely. Do not fly with these blades. Also check all linkages, balls, ball links and the swashplate links for clearance.

Do not check the blade tracking on the ground alone or with negative pitch.

Read the following pages before you go to test this!

Do not fix the helicopter to the ground or any object.

Keep some distance to the model and do not test this indoors!
