Control Stick
Length Adjustment
Neutralizing the Sticks
Brake and Ratchet
Stick Centering Force
Both sticks can be adjusted in length: By holding the lower half and turning
the upper part of the knurled handle, the screw is loosened. The control
stick is extended or shortened by turning it up or down
and then fixed by screwing each against each other of the upper and lower
part of the handle.
Both control sticks can be set from neutralizing to non-neutralizing and vice
versa. Consult the transmitter backside diagram to locate the corresponding
set screws.
The respective screw must be turned clockwise until the control stick is free
to move from stop to stop or counterclockwise until the control stick is again
self-neutralizing.
Note
Which of the two control sticks is to be switched to non-neutralizing also
depends on the choice of the control mode, see under "Commissioning the
transmitter".
On both control sticks, the braking force and strength of the ratchet can be
adjusted independently. Consult the transmitter backside diagram to locate
the corresponding set screws.
The inner set screw sets the braking force and the outer set screw sets the
strength of the ratchet of the vertical control direction of the respective
control stick.
The control sticks restoring force can also be adjusted. Consult the
transmitter backside diagram to locate the corresponding set screws. By
turning the respective set screw, the spring force can be adjusted:
Right turn = return harder Left turn = return softer
