Adjusting stick length
Both sticks are infi nitely variable in length over a
broad range, enabling you to set them to suit your
personal preference to provide fi ne, accurate control.
Loosen the retaining screw using a 2 mm allen key,
then screw the stick top in or out to shorten or extend
it. Tighten the grubscrew again carefully to lock the
set length.
Changing the stick mode
Either or both sticks can be converted from self-neu-
tralising to non self-neutralising (ratchet) action: open
the transmitter as already described.
If you wish to change the standard setting, use this
procedure:
1. Disconnect the centring spring from the appropria-
te neutralising arm using a pair of tweezers. If you
are not sure, move the stick to check. Raise the
neutralisation return arm and disconnect it.
2. Fix the ratchet spring (supplied)
to the plastic pillar using the black
self-tapping screw, then screw the
M3 screw in or out to set the desi-
red spring force on the side of the
hexagon sleeve.
3. Check that the stick functions
work correctly, then close the
transmitter case again.

Changing back to “self-neutralising” action
Open the transmitter as already described.
1. Remove the ratchet spring, as shown in the illust-
ration on the left.
2. Now re-connect the neutralising lever on the side
of the stick unit where the ratchet spring was loca-
ted.
3. First loosen the stick force adjustment screw
slightly – see the illustration on the next page –
and then draw a length of thin thread through the
top loop in the spring, but without tying it. Connect
the spring to the bottom loop of the adjustment
system using a pair of tweezers, then pull the top
end of the spring up using the thread, and connect
it to the neutralising lever. Once the spring is posi-
tioned correctly, withdraw the thread again.
4. Adjust the stick centring spring force as described
in the next section.
