  • Page 24 7. Fit the wheel pant in place and install using the two supplied bolts and washers. Use thread-lock to secure the bolts in place. Repeat the above steps for the other main gear.
  • Page 25 8. The tail wheel installation is very simple, the factory has installed most of the accessories, see the below picture. 9. Line up the caron fiber assembly onto the body of the aircrtaft and use the holes as a drill guide. Use a 2mm drill bit as a pilot hole, then apply thin CA to harden the wood.
  • Page 26 10. Drill another 2mm pilot hole at the end of the rudder and apply thin CA. It needs to be in a position where the spring is tensioned. Use a self tapping screw to secure in place. 11. The below is a picture of correctly installed tail wheel assembly. NOTE: One spare tail wheel spring is included in the spare hardware pack.

    COWLING INSTALLATION NOTE: There are pictures of different planes in this manual, however, this plane’s cowling is assembled the same way. 1. The cowl is secured with four 3 X 14mm bolts and washers.Apply nutlock onto the bolts as the vibration from the gas engine will shake them come loose.
  • Page 41 FINAL RADIO SYSTEM INSTALLATION Whether you use 72 MHz systems or the newer 2.4 GHz systems, correct radio installation and care is vital to the safe and reliable operation of your aircraft. Follow the manufacturer’s instruction for installation guidance of receivers and batteries paying attention to factors such as vibration isolation, adequate cooling, and clearances.
  • Page 42 To perform properly without being too pitch sensitive, you must not go too aft on the CG. GoldWing RC recommends an initial CG setting of 108-126mm(4.25-5 inches) behind the leading edge of the wing at the root. More experienced pilots may want to set the CG further aft for more 3D capability.
  • Page 43 Then install pull-pull ball links on control horns. Hook up the tail wheel spring. 3．Installation of stab Also the stab is removable for convenience in transportation, Attach elevators with 3x12mm Hex-head bolts and 10mm PTFE washers. Check these after every flight.
  • Page 44 4. Install the wings onto the fuselage being careful to align the wing tube with the wings and not force it. The wing tube may be initially tight but will loosen after some with use. Guide your servo wires into the fuselage openings and connect to the correct aileron channels.
  • Page 45 5.Side force generators Assembly. Cut the wing film needed to be install the SFG. Fixed the SFG Use M3X18 hand bolts and balsa sheets. Installation of the SFG is optional. 6. Fill your fuel tank making sure your vent line is not plugged or capped. With the canopy off, this is a good time to check for any fuel leaks.
