Turboprop radio setup
There are no special conditions needed for the turboprop as it uses the regular throttle stick in the
normal way. Follow the graphic below.
Pre-setting Radio to ECU
Confirm you have connected the ECU signal input to the throttle channel on your receiver.
Confirm you have connected the gearbox cable to the HUB and have a blue light which flashes on
rotation of the gearbox shaft or prop.
Connect the display to the Hub if your system is a Hub Lite or use buttons on the case for Compact Hub.
To navigate through the menus the two left buttons move up and down the menus, the two right buttons
increase and decrease the value set. When setting up transmitter setting use the plus button to confirm.
On all other adjustments there is no need to confirm any change of setting as changing a value
automatically updates it.
Connect the ECU and receiver batteries and note the display screen illuminates.
Remove rates, mixes, and throttle travel settings in the transmitter.
Before doing any adjustment on the ECU check your transmitter is sending correct signal by checking
the reading on the display:
From the opening screen, press the 2
nd
button from left once to show an information screen.
Note at top left a number showing the received radio signal shown as “Pulse = xxxxuS”.
It should be between 900-1050uS at ENGINE STOP position,
It should be between 1100 and 1300uS at IDLE position
And between 1800 and 2200uS at Full Power position.
Ignore the % reading to the top right for the moment.
Please note these readings are measured directly from the signal received from your R/C system, so you
should readjust your transmitter if the values read are outside that the ones suggested.
On some Futaba transmitters, it has been found that the throttle channel the sense of movement may
require reversing (servo reverse) and to repeat the transmitter alignment. The setting up assumes the
use of a transmitter (TX) with manual trims.
If you use a TX with digital trims, is essential to use the switch in the TX programmed for the
function "Throttle cut", or “engine cut” which normally has the effect of producing the “trim-
down” function. Using a digital trim cause unstable idle, and delay in shutting off the engine in
emergency.
Check your radio manual for this before you start. Avoid using the digital trim if at all possible.
Be careful not to use a spring loaded “Throttle Cut” switch as it will prevent the engine carrying out the
cooldown function. It must be a switch that stays in the position it is moved.
