18) With the servo horn centered, carefully
thread the second clevis onto the rudder pushrod wire
until the pin in the clevis lines up with the holes in
the control horn. Use your fingers to hold the push-
rod tube and keep it from turning.
❑
19) Snap the clevis into the fourth hole out from
the base of the control horn. See photo # 45 below.
❑
20) Remove the masking tape from the rudder
and double check that both the rudder and the rudder
servo are still centered.

21) With your radio system plugged in and
turned on, check the direction the rudder control sur-
face moves and the amount of control deflection. To
do this push right on the rudder control stick. The
rudder should move right. If it does not, flip the servo
reversing switch on your transmitter to change the
direction. (Refer to your radio guide for more infor-
mation on this function.)
❑
22) Push right completely on the rudder control
stick. While holding the control stick completely
right, use a ruler and measure the amount the trailing
edge of the rudder moves right. This measurement
should be 1". See figure # 5 below.

❑
23) If the control surface deflection is more or
less than 1" it must be changed. If your radio is
equipped with End Point Adjustments (EPA), make
those adjustments using the transmitter. (Refer to
your radio guide for further details.) If your radio
does not have this feature, you can still make the ad-
justments to the pushrod manually.
❑
24) If the rudder is moving more than 1", move
the clevis in one hole toward the center of the servo
horn to decrease the control deflection. If the rudder
is moving less than 1", move the clevis one hole closer
to the base of the control horn to increase the control
deflection. When adjusted properly, the rudder should
move 1" both right and left.
❑
25) When you are satisfied with the rudder con-
trol setup, apply a drop of Kwik Bond Thin C/A to
one of the threaded rods, where the clevis is threaded
on. This will prevent the pushrod from turning inside
the housing. You will still be able to turn the second
clevis if any further adjustments are necessary.
☛
Do not omit step # 25. Doing so may cause
drastic trim changes during flight or failure of the
pushrod assembly.
