Connect the elevator cable
Fit the drive arm extension to the elevator drive arm:
secure with an M4 x 25 bolt, washer and Nyloc nut
through the top hole. Tighten firmly and trim off any
excess bolt length.
Fit the elevator cable rod end to the elevator drive arm
with an AN3-10A bolt fitted through the lower hole in
the elevator drive arm and the centre hole in the drive
arm extension. Fit an AN960-416 (3/16”) flat washer,
then the rod end followed by an AN960-515 (1/4”) flat
washer and a Nyloc nut.
Do not tighten the Nyloc nut or the rod end lock nut until
the cable length has been adjusted in the next step.
Adjust the elevator travel
Use the supplied deflection templates to check the up and down travel of the elevator.
Hold the control stick all the way forward (have someone help you) and check the amount of
down deflection and adjust the cable length (by screwing the rod ends in or out an equal
amount at each end of the cable) until the down deflection is correct.
Now have your helper hold full back stick and check the amount of up deflection: it should be
very close to correct if the down deflection is OK, however you may need to make some fine
adjustments to equalise elevator travel until both up and down deflections are correct.
The elevator must clear the rudder and the down stop by 2mm at full deflection.
Recheck the up and down deflections and then lock the rod end lock nuts at each end of the
cable and mark each rod end lock nut with
TorqueSeal
. The elevator is now adjusted.
