XTC (Mk3) PROPORTIONAL SWITCHBOX CONTROLS (7 Service)
Machines with XTC Mk3 Proportional Controls (7 service) will be supplied with the control
unit shown below. The units for both electric and cable controlled rotor machines are
identical except that for cable versions the rotor control switches B, C & D (shown below) will
not provide a function as rotor operation will be controlled by a separate cable lever unit
(refer to specific cable rotor control page for operation details of that unit).
Identification & Function of Controls
*NOTE: On machines that feature a controllable 6
default using the ◄ ► buttons (H), this control can be swapped to operation by the LH
Thumbwheel (4) by activation of the D1 control panel button; in this case Slew is then
operated by use of the ◄ ► buttons (H). Control panel button D2 is used for any other
additional services that require on/off control only i.e. Debris Blower / Diverter Valve.
NOTE: By default the VFR function on Tele/VFR machines is controlled by use of the RH
Thumbwheel (5); the Tele function is configured to the D1 diverter control.
