Trainer 40 Instructions
9. Thread a plastic clevis keeper onto each of the two clevises. Holding the threaded pushrods using pliers screw the two nylon
clevises onto the ends of the pushrods. Open the clevises and snap them into the torque rod horns.

the pushrods
9.3 Connecting the clevises to the
torque rod horns
10. Holding in turn each aileron centred with the wing, mark the position where the pushrod crosses the 2mm hole in the servo arm
with a felt tip pen. Using a pair of pliers, bend the pushrod up through 90 degrees at this point and cut off the excess length,
leaving 6mm of pushrod after the bend.

11. Thread the pushrods into these holes followed by a swing keeper onto the pushrods, snapping the keepers into place

12. Reconnect the servo to the receiver and check that the ailerons are centred at neutral. The clevises can be undipped from the
torque rod horns and wound in or out to achieve this. Secure the arm to the servo using the manufacturer's screw. Finally, push the
clevis keepers closer to the torque rod horns. Note that one aileron will rise and one will fall - this is correct and is
necessary to effect a turn.
