Assembly Instructions – Read completely before starting assembly!

UNPACK :

Unpack your airplane and examine the components. Check for damage of any kind. If you have damage, please contact Extreme Flight to discuss. Contact info listed above.

WRINKLES :

Your airplane was packed in plastic at the factory without any wrinkles in the covering. You may notice some wrinkles now; more likely, you will notice a few in a day or two or the first time you take the plane out to the flying field. These wrinkles are the result of wood shrinkage and/or expansion. Balsa wood changes size and shape slightly as it is exposed to varying humidity in the air.

This is a natural property of balsa wood. As your airplane adjusts to the weather in your part of the world, wrinkles may appear and disappear. Wrinkles may be removed with the gentle application of heat to the covering material on your airplane. The best tools to use are a heat gun and covering iron.

Apply the heat gently: the covering material will shrink as you apply the heat, and this will remove the wrinkles. BE CAREFUL! Too much heat applied too quickly can damage the covering, either by causing it to pull away from the wood at seams and corners or even by melting it. The covering will shrink at low temperature with patient application of heat. Wrinkles in the covering DO NOT affect flight performance. If you must shrink on a color-seam, use the iron and go slowly and carefully to avoid any pulling or lifting at the seam.

Remove the canopy before attempting to use heat on your covering! The canopy is made of thermoactivated plastic and WILL deform with the application of heat. Do not apply heat to the canopy.

PAINT:

If you need to clean your airplane, we recommend using a damp towel. The paint used on the canopy and cowl is not safe for all cleaners. In particular, DO NOT use alcohol on these parts, it will remove the paint.

Items needed for completion:

• Masking or painters tape

• Hobby knife with #11 blades.

• Fresh 30 minute epoxy. Pacer Z-Poxy has worked very well for us for many years.

• Blue and Red Loctite.

• Small flat head and Phillips head screw drivers.

• Standard and needle nose pliers.

• Side cutters.

• Metric ball driver or allen key set. (especially 2.5 and 4mm drivers)

• Sanding block and sandpaper.

• Extreme Flight Servo Mounting Screws

• 7 400oz (min) torque metal gear servos. (8 servos if you use 2 rudder servos)

• 1 x standard size servo for the throttle.

• 4 x Extreme Flight 1.5” single aluminum Servo Arms for the ailerons (tapped M3)

• 2 x Extreme Flight 2” single aluminum arms for the elevators (tapped M3)

• 1 x Extreme Flight 4” double offset aluminum arm for the rudder (tapped M3)

• 2 x Extreme Flight 2-wire MPX Multi Plug (an quick and easy way to hook up wing servos)

• 3 X 24" Extreme Flight 20 AWG Servo Extensions (2 outboard ailerons 1 for throttle).

• 2 x 48” Extreme Flight 20 AWG Servo Extensions elevators and rear mounted rudder servo.

1. Before starting assembly, take a few minutes to read the entire instruction manual to familiarize yourself with the assembly process.

2. Go over all the seams on the aircraft with a covering iron on a medium heat setting. Also, due to climate changes, wrinkles may develop in the covering. These are easily removed with a little bit of heat. Use a 100% cotton tee-shirt and your heat gun and heat the covering while gently rubbing the covering onto the wood with the t-shirt. Be careful not to use too much heat as the covering may shrink too much and begin to lift at the edges. Take your time, and a beautiful, paint-like finish is attainable.

3. Apply CA to high stress areas such as servo mounting trays, landing gear mounts, anti-rotation pins, wing and stab root ribs, and motor box joints etc.

4. By the time your aircraft arrives at your door step, it will have been handled by a lot of people. Occasionally, there are small dings or imperfections on some of the surfaces. An effective method to restore these imperfections to original condition is to use a very fine tipped hypodermic needle and inject a drop of water under the covering material and into the ding in the wood. Apply heat to the area with a sealing iron and the imperfection will disappear. Deeper marks may require that this process be repeated a couple of times to achieve the desired result, but you will be surprised at how well this technique works.

5. Use high quality, fresh epoxy for installing the composite control horns and hinges. We highly recommend

Pacer Z-Poxy 30 minute Epoxy. We are very pleased with the results and ease of application and cleanup of these products.

6. Take the time to properly balance and trim your aircraft and set up rates with exponential values. Your flying experience will be greatly enhanced once your plane is properly dialed in.

7. Extreme Flight now has their own Vimeo channel. There are many assembly videos providing extreme detail on certain aspects of the assembly.

Let’s get started!

1. Locate the wing panels/ailerons and horizontal stabilizers/elevators and associated hardware bags.

We will begin by hinging all of these at one time. I strongly recommend 30 minute (or slower curing) epoxy for installing hinges. I have found it easier to apply 3-5 drops of glue in the hinge hole and then using a toothpick, or similar, spread the glue around the sides of the hinge hole. Do this on just one side, either the wing or aileron it does not matter which is first. Mix only enough glue to work with one panel at a time. Before applying any glue to the hinge itself, I highly recommend you protect the hinge pin (pivot point) from glue. I use Vaseline. Tape will work however it is harder to remove later. In any case apply either protectant to the center of the hinge so glue cannot penetrate the pin which may cause binding. Once you have the holes lathered with glue, apply a small amount to the hinge barbs and insert into the hinge hole until the pin is even with the hinge line. Be sure your hinge pivots freely and is perpendicular to the hinge line. Allow to dry then mate to the appropriate surface (wing to aileron/ horizontal stabilizer to elevator) and allow to dry.

***PLEASE NOTE*** there are 3 hinges that have been shortened to clear the tube socket. They are glued into the 3 inboard positions as shown.

2. Install the control horns for the ailerons. ***PLEASE NOTE*** There are three DIFFERENT control horns for the ailerons. The 106" Edge construction allows for three aileron servos per wing. Each control horn is drilled different for pushrod attachment. This is to keep control horn/pushrod geomentry consistent with all two or three servo positions. See the picture below for reference. The inboard control horn hole is the lowest on the horn. The outboard is the highest on the horn. If using two aileron servos per wing, use the inboard and outboard servo positions. Pay very close attention when separating and grouping the horns to be sure you are gluing the correct horns in the correct location!.

Insert the horns into the base plate and then temporarily install them in the aileron. Trace around the base plate with a fine tipped felt marker and then remove the horn and base plate. Use a sharp hobby knife to cut

2mm inside the line you marked and remove the covering. Scuff the bottom portion of the control horn that inserts into the hole of the control surface and the bottom of the alignment plate. Use epoxy to secure the control horns in place.

3. Install the aileron servos and orient the output shaft of the servo towards the leading edge of the wing.

We are using the Extreme Flight 1.5 inch servo arms for the ailerons. You will notice there are two types of ball links included: one standard ball link and one with a built in riser. The standard ball link is sandwiched between the control horns, the ball link with the riser is secured to the aluminum servo arm.

Thread the ball links onto each end of the turnbuckle pushrod. To secure the ball link to the control horns insert the 3mm bolt with integrated washer thru the control horn, then the ball link in the middle, then thru the other control horn, then the washer and nylon insert nut onto the other side. It is good practice to determine the pushrod length for one servo and match the other three to this length.

Electronically center your servo and install the aluminum arm perpendicular to the servo case. Secure the ball link with the riser to the servo arm. Do the same for the other servo locations. You will need to use the servo matching function in your radio or an external device to make sure the two aileron servos are perfectly synchronized and causing no binding. Failure to do so can destroy your servos in short order.

4. Install the elevator servos, orient the output shaft toward the leading edge of the horizontal stabilizer.

It will be easier to install the servo arms after mounting the servo. Make all hookups for the pushrods/ ball links as we did in the previous step. Again, it is good practice to make the pushrods the same length. I recommend using the 1.75" location on the 2 inch servo arm to maximize mechanical advantage and minimize the chance of flutter.

5. Rudder installation. The 106" Edge includes hinges and hinge rod to make the rudder removable. Be sure to take your time installing the hinges. Dry fit everything first! Be sure to orient the hinges consistently on each side/surface. Dry fit the hinges and install the hinge rod. Adjust hinge slots as necessary. Once satisfied with hinge fit and placement, apply glue to hinge slots. Using a zip tie end to guide the glue in the slots. Apply more glue to the hinge and insert. Do this for both the rudder and the vertical stabilizer. Clean up the excessive glue before install hinge rod. Mate the rudder to the vertical stabilizer with the hinge rod and adjust as necessary. Once satisfied, tape the rudder in place to dry. Checking frequently to clean up excess glue. Move the hinge rod and clean excess glue to allow the hinges to move freely. The hinge rod is held in place by a wheel collar installed at the bottom of the rod.

For most installations a single ultra high torque servo mounted in the pull-pull position will be the ideal way to power the rudder. We highly recommend the MKS HBL380 or 599 for this location. A double 4 inch Extreme Flight aluminum servo arm will provide plenty of travel while maintaining the best mechanical advantage and servo resolution. Two control horns are provided for the rudder. The slots for these must be located and opened with a sharp hobby knife. Install the control horns using the same technique as the ailerons and elevators. Please reference the above photos of this setup for detail.

Locate the slots for the pull-pull wires to exit the rear of the fuselage. Open these slots with a hot soldering iron. Install the pull-pull wires through the fuselage. The wires should run clear to the servo position.

Note: the pull-pull wires should cross inside the fuselage.

Install the rudder servo and center the double servo arm. Assemble the ball links and the pull-wire ends as shown. Thread the pull-wire end in the ball links four to five turns. This will allow room to tighten the wires after pull-pull wire installation is complete. Start at the rudder servo first. Thread the crimp sleeve on the wire first, then through the pull-wire end. Back through the crimp sleeve. Allow enough wire through the sleeve to loop back through the sleeve a third time. Once satisfied with the wire position, crimp the sleeve with a needle-nose pliers. After the wires are attached to the rudder servo, tape the rudder in the neutral position.

Use the same technique to attach the pull-pull wires to the rudder. Take as much slack out of the wires as possible before crimping the sleeves. Screw the pull-wire ends in to the ball links to take up the remainder of the slack. Note: you want the pull-pull wires to be taught but not "banjo string" tight. They should not sag at neutral position. After a few flights, recheck.

6. Next we will install the main landing gear, axles, tires, wheel pants and wheel cuffs. Use the provided bolts, washers and nuts from the main landing gear hardware kit to mount the carbon gear to the fuselage.

7. Install the landing gear plate cover over the mounting nuts. Glue in place with Goop style silicon glue. Slide the landing gear cuffs into place against the fuselage and secure with Goop style silicon glue. Tape in place until glue is fully cured.

8. Insert the axles into the holes on the landing gear leg and secure with a washer and lock nut.

Grind a flat spot on the axles to fasten the set screw against providing a better grip. Now install one wheel collar, the wheel then the other wheel collar but do not tighten. Now position the wheel pant onto the axle and determine the exact position of the inner and outer wheel collars such that the tire will not rub against the wheel pant. Once you have this location add blue thread lock to the set screw and tighten your wheel collars. Now position the wheel pant(s) onto the axle/gear and secure with the 3mm bolts/washers and use blue thread lock on these as well.

9. Next we will install the tailwheel. Locate the tailwheel hardware bag. Notice the included ball link. This will be installed in the bottom of the rudder for the tiller wire. It is good practice to remove all the set screws and bolts in the tailwheel assembly and reassemble using blue Loctite. On the bottom of the rudder, measure three inches from the hinge line. Make a mark to drill a 3/16 inch hole in the bottom of the rudder.

Mount the tailwheel assembly using the three M3 cap bolts and washers in the pre-installed blind nuts in the fuselage. Be sure to use blue Loctite on the bolts. Glue the ball link in the rudder with epoxy, using the tiller wire as a guide for depth.

10. Next we'll install the engine. There are laser marked locations to drill if using the DA-120. There is also a laser scribed cross to use a template for other engine makes. Drill for 1/4x20 mounting bolts at the proper locations.

11. Install the DA-120 using the Blazing Star one inch mount with BOTH 2mm and 3mm Delrin spacer provided with the mount. Be sure the spacer goes between the mount and plywood firewall, not against the engine. Secure using 1/4x20 bolts, washers and lock nuts (not included). Total distance from the front of the motor box to the rear of the spinner backplate is 7 7/16" or 189mm.

12. The throttle servo is mounted to the bottom of the motorbox in the cutouts provided. Use a rotary tool the open the bottom of the cowl to fit the mufflers and to provide an exit for air. A pipe tunnel is provided along with vent covers for the bottom of the fuselage.

13. Secure your choice of tank to the tank tray over the carbon wing tube with Velcro or cable ties. We used the

EF Flowmaster 34 ounce tank and fuel tubing along with an EF fuel dot.

14. Install the remainder of electronics and radio equipment.

15. Slide the wing tube into the fuselage and slide the wings onto the tube. Secure using two wing bolts and two hairpins secured to the aluminum pin forward on the wing.

16. The prefinished canopy is secured by four M3 thumb screws

17. A set of SFG's and wing tips are included. They are secured with M3 cap bolts. Blind nuts are installed in the wingtips for mounting. Use the SFG's as a guide to locate the blindnuts. Open the covering with a hot soldering iron.

Control Surface Throws

High Rate:

Ailerons – 40-42 degrees

Elevator – 55-60 degrees

Rudder – Maximum throw available without interference

High rate controls typically use 50-75% exponential

Low Rate:

Ailerons – 15 degrees

Elevator – 20 degrees

Rudder – 30 degrees

Center of Gravity

The preferred CG for this plane is at 5.5” back from the leading measured at the wingtip. This is the recommended CG to start with and can then be tuned for a specific style of flying.
