Using the + button, scroll through the selections until the AUX-channel func is displayed.

There are three selections in the AUX-channel func menu. While pressing the Change Value button, use the + or - button to scroll through the selections.

	:ON Turb Ctrl ON	Aux channel enabled for speed limiter functions and/or Smoker. Turbine control enabled
	:ON Turb Ctrl OFF	Aux channel enabled for speed limiter functions and/or Smoker. Turbine control disabled. You still need to use the AUX channel for speed limiter and/or smoker functions but the turbine control will be in Single Channel Mode.
	:Not Used	Single Channel Mode. Totally disable the AUX channel input for engine control, speed sensor and smoker functions. AUX channel wire does not need to be connected to the receiver in this mode. If Not Used is selected and you have a speed sensor, the Maximum Limit Speed is still active limiting the maximum speed your plane will fly. You cannot disable this safety function.

Single Channel Mode start/stop procedure.

To start the turbine, place the throttle stick and trim to their minimum positions. Next, move the trim to its maximum position. This will initiate the LED chase. Finally, move the throttle stick to its maximum position and the engine will start. To stop the startup, move the throttle stick and trim to there minimum position.


To stop the engine after it is running, throttle up just above idle and let it stabilize for a couple of seconds then move the throttle stick and throttle trim to there minimum position. The auto-cool down mode will start when the engine has nearly stopped rotating.
