Install the Ailerons CA hinges Apply instant glue (C.A.glue,super glue) Ensure smooth non‐binding Assemble left and right Movement while assembleing. S ides the same way. 3/32 DRILL A HOLE DEEP IN CENTER OF HINGE SLOT Step 1: Drill a 1/16‐inch hole into the center of each hinge slot in the aileron and wing panel. Trim the covering away from each hinge slot to ensure that the hinges will be properly glued in place. Step 2: Test fit a CA hinge into each of the hinge slots. If necessary, enlarge the slots with a hobby knife. When satisfied with the fit, place the hinges into the slots. Push a pin through the middle of each hinge to keep them centered. ...
Page 5
Step 3: Join the aileron to the wing panel and remove the pins from the hinges. Center the aileron on the wing. Step 4: Adjust the aileron so there is a small gap between the LE of the aileron and the wing. The gap should be about 1/64‐inch or just wide enough to slip a piece of paper through. ...
Page 6
Step 5: Apply six drops of thin CA to the top and bottom of each hinge. Do not use accelerator in the hinging process. The CA must be allowed to soak into the hinge naturally. After the CA has cured, flex the surfaces several times to break in the hinges. Pull on both surfaces to make sure the hinges are secure. Repeat steps 1‐5 for the other wing panel.
Install the Aileron Servos & Pushrods Round head machine screws for control horns PM2X25mm Nylon control horn Nylon Clevis EZ link for pushrod Z‐Bend Before installation, confirm that the servos you will be using will properly fit in the servo opening. Make adjustments as necessary for your servos. The pre‐cut servo openings on this airplane will fit most standard size servos. Step 1: Installing the servos in the wing will require the use of a servo extension wire for each aileron servo. One Y‐harness connector is also required and is used to allow the aileron servos to plug into one slot in your receiver. You may also have a computer radio that allows you to plug the servos into separate slots and then mix them together with the radio transmitter. If you choose to mix them together with the radio rather than a Y‐harness, refer to the manual for your particular model radio system. Step 2: Attach the servo extension to the aileron servo and secure it with heat shrink tubing. The tubing can be shrunk around the connector with a heat gun or micro torch. If your aileron servo has tabs molded into the case for mounting the servo on its side, they must be cut off in order for the servo to fit into the servo bay in the wing panel. Follow the instructions included with the servo for cutting the tabs. Install the eyelets and grommets included with the servo. ...
Step 3: Securely tie the string from inside the opening for the aileron servo to the end of the servo extension. Pull the servo wire and extension through the wing. ENLARGE TO CUT OFF UNUSED ARM LEADING EDGE SERVO ARM PARALLEL WITH HINGE LINE Step 4: Temporarily position the aileron servo into the servo bay. Install and remove a servo mounting screw into each of the four holes. Apply a drop of thin CA into the holes to harden the wood. After the glue has hardened, install the servo into the opening. Cut three arms from a four‐armed servo arm (arms may need to be purchased separately). Center the servo with your radio system and install a servo arm parallel to the aileron hinge line as shown. ...
Page 9
Step 5: Place one of the nylon control horn on the aileron, positioning it as shown in the sketch and aligning it with the servo arm using a straight edge as a guide. Mark the location for the screw holes. Using a Ф1.8mm drill bit, drill a hole through the aileron at the marks you made. Install and remove a PM2 x 25mm sheet metal screw into each of the holes. Harden the holes with a drop of thin CA. After the glue has hardened completely, install the control horn with two PM2 x 25mm sheet metal screws. SILICONE CLEVIS RETAINER 1.8 X 170mm Ф PUSHROD WIRE NYLON CLEVIS Ф1.8X 17 mm Nylon Clevis Aileron Pushrod The c levis needs to be sec ured onto the pushrod for about 8mm...
Page 10
Step 6: Locate a Ф1.8 x 170mm pushrod wire threaded on one end. Screw a nylon clevis onto the rod. It is recommended you use a clevis retainer (not included) to help keep the clevis in place. Slide a silicone clevis retainer onto the base of the clevis. Connect the clevis to the second hole on the control horn. Ф1.8X 17 mm Aileron Pushrod Servo Arm Faslink Bend the end of the wire into a right angle. Depending on the length of the wire needed, exc ess wire c an be removed.
Page 11
NYLON FASLINK 7. Use tape or a small clamp to hold the aileron in the neutral position. With the servo arm still parallel to the hinge line, make a mark on the pushrod where it crosses the outer hole in the servo arm. Remove the pushrod and clevis from the control horn and make a 90 degree bend at your mark. Cut off the excess pushrod wire 6mm beyond the bend. Enlarge the outer hole in the servo arm using a 2mm drill bit. Connect the pushrod to the servo arm using a nylon FasLink.
Finish the wing panels Socket head screws for securing wings to fuselage CM4X20mm Ф19X400mm Aluminum wing tube Step 1: Use the wing tube to attach the wing halves to the fuselage. METAL WING BOLT Step 2: Test the CM4X20mm wing bolts into the blind nuts in the wing panels. If the bolts are difficult to thread into the blind nuts, insert a tap into the nuts to clean up the threads. Step 3: Install the wing panels onto the wing tube and secure them to the fuselage using two metal wing bolts.
Install the Stabilizer Step 1: Locate the horizontal stabilizer slot under the covering on the tail section of the fuselage by lightly pressing with your finger. The slot is located on both sides of the fuselage. Carefully remove the covering. Make sure you do not cut into the wood. Step 2: Locate the slot for the vertical fin on the top of the fuselage and remove the covering. Make sure you do not cut into the wood. ...
Page 14
Step 3: Insert the stabilizer into the stabilizer slot so it is centered in the fuselage (dimension A should be equal). Place the wing onto the fuselage and secure it in place with the wing hold‐down bolts. View the plane from the rear and at a distance of a few feet. The stabilizer should be parallel to the wing (dimension B should be equal). If not, sand the stabilizer mounting base slightly to achieve the proper position of the stabilizer. Step 4: Attach a piece of string to measure the distance “A” of each stabilizer halves, and “B” the difference between the wing tip and the top of stabilizer. Both distances should be equal. ...
Page 15
Step 5: With the stabilizer properly aligned, use a felt‐tip pen to trace a line around the tail of the airplane on the top and bottom of the horizontal stabilizer. Step 6: Remove the stabilizer and draw two additional lines, top and bottom, 1/16" [1.6mm] inside the lines drawn in the previous step. Using a knife, carefully cut through the covering along the inside lines and remove the covering from the center. Do not cut the wood under the covering! If the covering is not removed from the stabilizer, a proper bond for your adhesive will not be achieved. Step 7: Mix 30‐minute epoxy and spread some inside the horizontal stabilizer mount on the fuselage. Spread more epoxy onto the top and bottom of the stabilizer where the covering was removed. Insert the stabilizer into the fuselage from the rear and adjust the alignment using the guide lines that were drawn onto the stabilizer. Wipe off any epoxy that squeezes out using a paper towel dampened with rubbing alcohol. Recheck the alignment frequently while the epoxy cures. ...
Install the Vertical Fin Step 1: Test fit the vertical fin in the slot in the top of the fuselage. Sand the edges of the slot if necessary to obtain a snug fit. Draw a line around the vertical fin where it meets the fuselage. Cut the covering 1/16” [1.6mm] inside the lines you drew on the vertical fin and the top of the fuselage. Remove the covering. Step 2: Mix some 30‐minute epoxy and apply it to the top of the horizontal stabilizer through the slot and on the sides of the slot. Apply more epoxy to the vertical fin where the covering was removed. Insert the vertical fin into the fuselage and adjust the alignment. Check for a 90 degree angle between the vertical fin and horizontal stabilizer when viewed from the rear. Use masking tape to hold the vertical fin in this position. Recheck the alignment frequently while the epoxy cures. ...

Joining the Elevator Halves Step 1: Without glue, position the elevator halves on the stabilizer. Measure and mark a centerline onto the elevator joiner wire. Center the joiner between the two elevator halves. Mark the position where the joiner will enter the elevator halves. Step 2: Remove the elevator halves from the horizontal stabilizer and drill straight into the leading edge of the stabilizer using a 1/8" [3.2mm] drill bit at the marks. Drill into the elevators 1‐1/4" [32mm] to allow for complete insertion of the elevator joiner. This step is done best using either a pin vise or twisting the drill bit into the wood with your fingers. ...
Page 18
Step 3: Carefully cut grooves into the leading edges of the elevator halves to allow the joiner to recess into the leading edge. ...
Page 19
Step 4: Use a straightedge to align the elevator halves on a flat surface. Using 6‐minute epoxy, glue the joiner wire into position. Make sure the joiner wire is fully seated in the elevator halves before the epoxy cures. Use weights to keep the elevator halves from moving. ...
Install the Elevator Step 1: Find the pre‐cut hinges from the included accessories. Test fit the hinges in the slots in the elevator halves and stabilizer. If the hinges do not slide into the slots easily, work your knife blade back and forth in the slot a few times to provide more clearance 3/32 DRILL A HOLE DEEP IN CENTER OF HINGE SLOT Step 2: Drill a 3/32” [2.4mm] hole, 1/2” [12.7mm] deep in the center of the hinge slots. Use a rotary tool with a 3/32” [2.4mm] drill bit or a carbide cutter for the best results. Reinsert your knife blade to clean out the slot after you drill the holes. Step 3: Insert four hinges into the slots in the stabilizer. Press the elevators onto the hinges until the gap between the elevators and stabilizer is about 1/32” [.8mm]. Flex the elevators a little in one direction, but do not allow them to pull away from the stabilizer. Apply six drops of thin CA onto each hinge. Turn the fuselage over and apply six more drops of thin CA to the other side of each hinge. DO NOT use accelerator while hinging, as the CA must wick into the hinge to properly attach the hinges. Use a paper towel to absorb any excess CA. After the CA cures, flex the elevators in both directions to free up the elevators for operation. ...
Page 21
Step 4: Temporarily insert a pushrod into the elevator pushrod exit slot. Use the position of the pushrod to align the elevator control horns onto the undersides of the elevator halves. Mark the locations of the control horn mounting holes onto the elevator halves and drill holes at the marks. Do not drill all the way through the elevator halves! Thread a screw into the hole and back it out. Apply a couple drops of thin CA glue to the hole and let it harden. Attach the elevator control horns to the elevators using four screws. ...

Install the Rudder and Tail Wheel Step 1: Assemble the tail wheel assembly set using the included accessories. Step 2: The installation tab of the tail wheel need to be mounted on the bottom of the fuselage. Test fit the rudder to the fuselage with the tail wheel assembly installed in the orientation shown. Make any adjustments necessary so the tab on the tail wheel is securely fastened on the fuse. Roughen the wire on the tail wheel assembly that fits into the rudder with sand paper and clean it off with alcohol. Glue the tail wheel wire into the hole in the LE of the rudder with medium or thick CA glue. Fit the rudder to the fuselage along with CA hinges. Glue the CA hinges in place with thin CA glue. ...
Page 23
RUDDER EXIT SLO T Step 3: As you did with the elevator, use the pushrod to temporarily position a control horn onto the side of the rudder. Then secure the control horn using two screws. ...
Page 24
Installing the Tail Servos and Pushrods Step 1: Install the elevator and rudder servos into the fuselage as shown using the hardware supplied with the servos. Be sure to harden the screw holes with thin CA as was done with the aileron servos. Cut three arms from two four armed servo arms. Center the servos with your radio system and install them onto the servos with the servo screws. Enlarge the outer holes of each servo arm with a 5/64" [2mm] drill bit. Depending on your balancing needs, you can install the receiver battery in the front of the fuselage or at the back of the fuselage. RUDDER EXIT SLOT Step 2: Thread the clevis securely onto the rudder pushrod. We recommend using a clevis retainer to help keep the clevis in place. Slide the pushrod through the rudder pushrod exit slot in the fuselage and connect it to the rudder control horn. ...
Page 25
Step 3: With the rudder in the neutral position and the rudder servo arm perpendicular to the pushrod, mark where the pushrod crosses the outer hole of the servo arm. As you did with the aileron pushrods, make a 90 degree bend at the mark and cut off the excess pushrod 1/4" [6mm] beyond the bend. Secure the pushrod to the servo arm with a FasLink. Make any adjustments necessary to the nylon clevis so that the rudder is properly centered and slide the silicone clevis retainer to the end of the clevis. Step 4: Thread the clevis securely onto the elevator pushrod. We recommend using a clevis retainer to help keep the clevis in place. Slide the pushrod through the elevator pushrod exit slot in the fuselage and connect it to the elevator control horn. ...

Option 2: Nitro Motor and Fuel Tank Installation Installing the Fuel Tank Step 1: The fuel tank can be assembled as a two line system consisting of a vent (pressure) line to the muffler and a carb line. Filling and emptying of the tank would need to be done through the carb line, or an optional fuel fill valve. The tank can also be assembled as a three line system having a vent line, carb line, and fill line. If installing a fill line, puncture the top of the stopper above the sealed off fuel tube hole. The fill and carb lines should extend out 13mm beyond the stopper and the vent line should be bent upwards and left uncut. With the tubes installed in the stopper, the stopper plates loosely in place with the PM3x25mm screw to hold the assembly together. ...
Page 35
To p o f t an k Ven t Fill an d c arb lin es Step 2: Fit the stopper assembly into the tank with the vent line pointing toward the top of the tank, but not touching. The fuel tubing and clunks (fuel pickup) on the carb and fill lines should almost reach the back of the tank but not touch. The clunks must be able to move freely inside the tank when assembled. Adjust the length of the fuel tubing accordingly. When satisfied, tighten the PM3x25mm screw in the stopper to secure it in place (do not over‐tighten). Mark the side of the tank that must face up when installed in the plane. We also suggest marking the tubes in the stopper. ...
Page 36
Step 3: Insert the tank into the fuselage with the correct side facing up. The fuel tubing should be routed through the hole in the center of the firewall. ...

5. Install the Cowling Self‐tapping screws for securing cowling PWA3X12mm Step 1: Before fitting the cowling, make any cutouts necessary for your power system. For example, for a glow engine, a cutout must be made for the engine head, exhaust outlets, and needle valve access. A rotary tool such as a Dremel drill works very well for cutting holes in fiberglass. Step 2: Apply a piece of masking tape to each side of the fuselage in the location shown. Draw a line on the masking tape where you want to install the cowl mounting screws. You have a total of 4 mounting screws, 2 on each side of the cowl. ...
Page 40
Step 3: Fit the cowl to the fuselage and align it with the colors on the fuselage. Temporarily install the spinner backplate onto the motor shaft and make any adjustments to the cowl position so that the backplate is centered with the front of the cowl. When satisfied, tape the cowl into position. Measure 9.5mm forward from the aft end of the cowl at each of the line you made on the masking tape. Mark the cowl for each of the four cowl mounting screws. PAW3 X1 2 mm Step 4: Drill 1/16" [1.6mm] holes at the marks you made on the cowl through the cowl mounting blocks. Remove the cowl and thread a self‐tapping screw into each hole in the cowl mounting blocks and back it out. Apply a couple drops of thin CA to each hole in the blocks. Enlarge the four holes in the cowl with a 2.4mm bit. ...
Installing the Receiver Step 1: Secure your receiver inside the fuselage. Then connect the servos to your receiver. Make sure the leads to not interfere with any of the pushrods. Step 2: Pre‐cut openings are provided for mounting an on/off switch. If the hole spacing does not fit your switch, you may need to modify the pre‐cut opening, or mount it in a different location. You can also mount an optional charge jack receptacle below the switch ...
Balancing the Model After you have finished building the model into ready‐to‐fly condition you can set the C.G. of the model. You need to have all of the systems installed before you begin, including the nitro engine or electric motor, landing gear, radio system, and battery pack. The C.G. is located 4‐15/16" [110mm] back from the leading edge of the wing at the fuselage. This is where your model should balance for the first flights. Later you may wish to experiment by shifting the C.G. forward or back to change the flying characteristics. Moving the C.G. forward may improve the smoothness and stability, but the model may then require more speed for takeoff and make it more difficult to slow for landing. Moving the C.G. aft makes the model more maneuverable, but could also cause it to become too difficult to control. When balancing your model, support the plane upright at the C.G. position on the bottom of the wing with your fingers or a commercially available balancing stand. Move the battery or receiver inside the fuselage as necessary so the model hangs level or slightly nose down. This is the correct balance point for your model. After the first flights, the CG position can be adjusted for your personal preference. ...
