Section 8: Attaching the Control Horns
Next, you are going to attach all of the control horns, you will need:
•
1 Elevator control horn
•
1 Rudder control horn
•
2 Aileron control horns
Insert the control horns into their appropriate pocket. The Rudder control horn goes on the
RIGHT side and the elevator horn goes on the LEFT side. Left and right is as if you were
sitting in the cockpit looking forward. After checking to make sure that they’re aligned
properly, glue them into place with thin CA.
Section 9: Installing the Servos and Control Rods
1.
The tail feather servo holes in the plywood crutch are sized for HS81 size servos.
2.
Place the servos in the holes with the control horns towards the front of the fuselage. Screw
the servos into place and then remove the screws and servos. Flow some thin CA into where
the servo screws screw holes to strengthen the wood, creating tough “threads”. Allow the glue
to dry completely and then reinstall the servos and screws. Do not over-tighten the screws.
3.
Do the same procedure for the aileron servos. The control horn ends should be facing towards
the ailerons. You’ll need to thread the servo wires with extensions through the wing. Place a
strip of tape around the connectors to keep it from coming unplugged.
