❑
Using a modeling knife, cut away and remove the two
lower arms from a "4-point" servo horn. Your servo horn should
look like the drawing at left.
❑
Plug the aileron servo into the receiver. Plug the ESC into the receiver and the flight battery into the ESC. Turn on the
radio system and center the servo using the trim lever on the transmitter.
❑
Use a couple of pieces of masking tape, taped between the wing and the ailerons, to hold the ailerons centered.
❑
Thread one nylon adjustable control horn onto each
aileron torque rod. When threaded into their final positions,
the center of the control horns should be 9/16" above the
surface of the wing.
❑
Carefully bend the two 4" long pushrod wires exactly the
same way as you bent the elevator and rudder pushrod wires,
and connect them to the adjustable control horns, as shown.
☞
Notice that the pushrods are installed with the V-shaped
bends toward the outside of the wing. This makes it easier to
adjust the pushrods.
IMPORTANT NOTE ABOUT AILERON SETUP
We are going to set up the aileron servo horn slightly different than what you might be used to. We are going to set it
up so that the ailerons have differential. Normally, both ailerons move up and down the same amount. Differential
ailerons means that one aileron moves up farther than the opposite aileron moves down. Using aileron differential
helps eliminate the flight dynamic referred to as adverse yaw. Adverse yaw is when the airplane wants to yaw around
the opposite axis as it rolls. For example, when the airplane rolls to the right, the airplane also wants to yaw to the left.
Without aileron differential, this adverse yaw can result in an airplane that is difficult to control and/or does not turn
properly. We can counteract this tendency with aileron differential. The following procedures will detail how to set up
your Odyssey EP ARF with the correct amount of aileron differential.
❑
Glue the servo tray assembly into place using a generous amount of thick C/A and hold the servo tray in place until the
C/A fully cures.
