❑
Thread the nylon clevis onto the threaded end of the
pushrod wire until the clevis lines up with the holes in the
control horn.
☛
Use needle nose pliers to keep the pushrod wire from
twisting.
❑
Carefully snap the clevis into the third hole out from the
base of the control horn and slide the piece of silicon tubing
up over the clevis to secure it into place.
Step 3: Adjusting the Pushrod & Control Throw
❑
Remove the masking tape from the elevator.
❑
With your radio system plugged in and turned on, check to make sure the elevator and the elevator servo are centered.
If necessary, use the trim lever on the transmitter and/or thread the clevis in or out to center the elevator.
❑
Double-check that the elevator is moving in the proper direction.
❑
Check the control surface throw by measuring from the
widest point of the control surface. The elevator should move
both up and down 1/4".
IMPORTANT
Remember, you can adjust the control throws by moving the ends of the pushrods in and out on both the control horn and
the servo arm. Moving the pushrod toward the control surface will increase the control throw. Moving it away will
decrease the throw. Moving the pushrod toward the center of the servo arm will decrease the control throw and moving
it away from the center will increase the throw.
WARNING
We strongly suggest using the recommended elevator control throw listed above for your first few test flights, or at least
until you are familiar with the flying characteristics of the airplane. Using a higher control throw without being familiar
with the flight characteristics will only result in excessive pitch control which will likely lead to over-controlling.
❑
Use a couple of pieces of masking tape to hold the elevator centered.
