Single or two channel operation?
The turbine may be operated with either one or two channels from your receiver (throttle only or throttle
and an auxiliary channel). If single channel is selected, starting, stopping and controlling the power is all
accomplished with just the throttle channel. If two channel operation is selected, an auxiliary channel can
be used to start, stop or optionally control other special features of the ECU like the smoke pump and
airspeed control explained later in the manual. Most commonly, one channel is used.
How to set your ECU for single channel operation
Single channel operation can be selected automatically by not connecting the auxiliary channel cable to the
receiver. When you are in the
learn R/C
mode, it will detect the auxiliary channel is not plugged in and will
automatically change to single channel operation (auxiliary channel =
Not Used
).
To manually select one or two channel operation, follow the instructions below. This is required for
changing from single to two channel operation.
Plug in the GSU and power up the system.
Press the
Limits
key.
Using the ►+ key, scroll through the selections until
AUX-channel func
is displayed.
There are three selections in the
AUX-channel func menu
. While pressing the
Change Value
key, use the ◄ - or ►+ key to scroll through these selections.
:ON Turb Ctrl ON
Aux channel enabled for 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 turbine 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.
Setup failsafe mode
The ECU has the unique ability to shut-off your turbine if you have a radio failure. This is accomplished by
detecting that the signal from the receiver’s throttle output is either missing or outside the values that were
learned during setup.
YOU ARE REQUIRED TO USE THE FAILSAFE!
This will not instantly shut off the turbine. A timer is started when the failsafe condition occurs and the
turbine will immediately go to idle. After 2 seconds (AMA requirements as of March 1, 2004) the turbine will
then shut off. This 2 second timer is reset back to zero anytime a non-failsafe condition is met. Your R/C
signal must be broken for at least 2 continuous seconds before the turbine is shut off.
Setting the failsafe
The following procedures are for most radios like JR, Futaba or Airtronics/Sanwa

The following failsafe instructions are for PCM or Spread Spectrum receivers only. (PPM
Receivers are not allowed under AMA rules.)
