What you will need in this chapter:
One Airframe
Four carbon fiber push rods
Eight metal push rod ends
Four sets of aluminum control horn assemblies
One Aluminum rudder control horn assembly
Six 4/40 ball links
One 20oz Du-bro fuel tank
Not Provided:
Two 100oz or better servos for ailerons
Two 130oz or better servos for elevators
One 150oz or better servo for rudder
One Fuel dot or other fueling device
JB weld or Rubber Toughened CA
½ inch low tack masking tape
Some foam rubber for mounting receiver, ignition module, and fuel tank
Install 100oz or better servos for the ailerons in the servo trays located in the bottom of the wings.
Install 130oz or better servos for the elevators in the servo trays located in the rear of the fuselage.
Install one 150oz or better servo for the rudder in the center servo tray inside the fuselage.
Install the aluminum control horn assemblies to each surface with the M4 bolt in the down position. Use
blue loc-tite on the aluminum base to ensure the bolt does not try to back out during flight. Screw on the
horns centering them on the remaining M4 bolt.
Do not use loc-tite installing the horn.
Tip#6 Installing your servo arms. We used high quality aluminum 1.25-inch arms on the aileron servos, 1.5-
inch arms on elevator servos, and one 3-inch arm for the rudder. We also installed our 4/40 ball links and
pushrod ends to the elevator and aileron servo arms prior to mounting the servo arms to the servo.
