Stick centring spring tension
The stick centring force can be adjusted to suit the
pilot’s personal preference. The adjustment system is
located adjacent to the stick centring spring. Rotate the
adjuster screw using a cross-point screwdriver until the
spring tension feels right to you:
Turn to the right = harder spring tension; •
Turn to the left = softer spring tension. •
Changing the stick mode
Either or both sticks can be converted from self-neutral-
ising to non self-neutralising action: start by opening the
transmitter as described on the previous page.
The procedure for changing the default stick mode set-

of thin thread through the upper loop of the spring –
but don’t tie it. Now use a pair of tweezers to connect
the spring to the bottom loop of the adjustment sys-
tem, and then engage the top end of the spring to the
centring lever using the thread. Once the spring is
correctly fi tted, the thread can be removed again.
