2. Prepare the aileron servo by installing the rubber grommets and brass eyelets following the instructions provided with the servo. 4. A string has been installed in the wing to pull the aileron servo extension through the wing. Tie or tape the string to the end of the extension. Hint: Prepare all the servos for your model at this time. Don’t forget to prepare the retract servo as well if you are installing the optional retracts. 7. Use a pin vise and 1/16-inch (1.
9. Use the screws provided with the servo and a #1 Phillips screwdriver to secure the aileron servo in the wing. 11 Attach the 31/2-inch (89mm) pushrod wire to the servo horn using a nylon pushrod keeper. You may need to use pliers to snap the keeper on the wire. Slide a silicone clevis keeper on a clevis. Thread the clevis on the pushrod wire. With the servo centered, connect the clevis to the center hole of the control horn. Make sure the aileron is centered when the clevis is connected.
2. Place the landing gear block in the wing. Use a pencil to transfer the locations for the mounting screws onto the landing gear rails. 4. Place 2–3 drops of thin CA in each of the holes to harden the surrounding wood. This will help prevent the screws from vibrating loose. 7. Use a flat file to make a 1/4-inch (6mm) wide flat area on the end of the landing gear wire. Create a second flat on the wire that is 7/8-inch (22mm) from the end of the wire. 5.
9. Slide one of the 4mm wheel collars onto the wire. Tighten teh setscrew on the flat made next to the bend in the wire. Next, slide the wheel into position. The last wheel collar can now be placed on the landing gear wire. Position the collar flush with the end of the wire and use a 3mm x 3mm setscrew to secure the outer wheel collar. Check that the wheel can rotate freely. If not, reposition the collars until the wheel rolls with little resistance.
2. Use a hobby knife and #11 blade to remove the 4. Use a hobby knife and #11 blade or razor saw to trim covering on the top and bottom of the wing for the nose gear the plate to the edges of the notch in the leading edge. Use retract. medium grit sandpaper to smooth the edges where the plate was cut. 6. Use a hobby knife with a #11 blade to remove the covering from the wheel well. Use a covering iron to seal the edges down in the wheel well and leading edge of the wing. 7.
8. Remove the retract from the wing. Use a drill and 3/32-inch (2.5mm) drill bit to drill the holes for the mounting screws. Make sure to place the drill bit as far as possible in the drill chuck to help prevent drilling through the top of the wing. 9. Place 2–3 drops of thin CA in each of the holes to harden the surrounding wood. This will help prevent the screws from vibrating loose. 10. Repeat Steps 6 through 9 to prepare the remaining landing gear mount for the landing gear block. 12 11.
15. Place a drop of light machine oil on the axle. Assemble the wheel and axle as described in Step 18. Use a setscrew to secure the axle to the mount. Make sure to use threadlock on the setscrew to prevent it from vibrating loose. 17. Slide the strut into the retract mechanism. Note the position of the strut in relationship to the retract mechanism. The wire below the coil will be toward the air cylinder and the coild facing as shown in the photo. The coild will be perpendicular to the air cylinder.
21. Pull the previously installed air line out of the wing near the retract opening and connect the airline to the retract air cylinder fitting on the retract. 23. Slide the wheel assembly on the strut. Check that the wheel is pointing straight ahead and parallel to the fuselage centerline. Tighten the setscrews on the axle mount to leave marks on the wire strut. 22. Mount the retract in the wing using four #6 x 3/4-inch sheet metal screws.
