Pilot RC Control Horn Installation

(50cc and larger have dual control horns & 30cc Aircra have a single control horn)

• Rubber/Latex Gloves.

• Epoxy (30 Minute or Stronger)

• Epoxy Mixing Cups

• Epoxy Mixing Sticks (Any mixing stick that will t into the slot)

• Denatured Alcohol or Acetone.

• Paper Towels

• Sand Paper

• X-Acto Knife

• Dremel and Small Drill Bit (Optional and Not Always Needed)

en Prepare your parts..

en you will need to test t your parts together before gluing in place. Please note that sometimes the slots need to be cleaned out a little bit and can be done with a dremel and a small drill bit or an x-acto knife.

Force your epoxy into the slots. Also apply a thin layer of epoxy on the control horn and bottom of the guide plate.

Install your horns. Make sure to clean o any epoxy that comes out from under the plate with a paper towel and alcohol.

Pilot RC

Wing & Elevator Servo Installation

You will need:

• Hobby Iron

• X-Acto Knife

• in CA “Super Glue”

• Drill and Drill Bit

First nd the servo mounting hole and iron around to assure that the covering is stuck to the surrounding wood.

en cut like this or to your preference.

en press and iron excess covering down into the servo slot.

Now you can pre t the servo.

Make sure your grommets are installed and drill the holes for the servo screws.

Now apply a small amount of the CA to the already drilled servo screw holes and if needed run your extension wire through. (Don’t forget the safety clip!!)

Now you can install the servo with your choice of screws and attach the linkage.

Final adjustment of turnbuckles and it ready for servo adjustment.

Pilot RC Optional Rudder

Installation for 50-150cc Aircraft

Shorten the rudder wire so that it will not pierce the covering at the top of the rudder and leave about 3/4” hanging out the bottom. Bend the bottom at a 90 degree angle, and then trace around the wire (See Photos). You then carve out a channel for the wire to t into, it only needs to be a deep as the wire is thick.

e Tail wheel bracket will lock it in to place. Make sure it overhangs the slot when you install the TW bracket.
