ducing 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.
Do 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.
Aligning transmitter with ECU
As the display does not photograph well we have reproduced the display readings as a green box.
Turn on the transmitter and receiver. The opening screen should show as below. Follow the steps
shown to set your radio:
The correct adjustment of the throttle adjustment on the ECU can be verified in the second screen
of the display as used before. The percentage of the throttle position should read 0% at the posi-
tion of engine stop (trim and stick down), 100% with stick/trim full up and between 15% and 30%
at idle.
We have heard problems in operation where very low trim values have been set, as the ECU
struggles to differentiate between a run and stop signal.
Make sure you programme in at least 15% travel for trim up.
This now completes your radio setup and should only need doing again if the radio settings are
changed like if you have had the engine in for service or repair.
