Hi (I post this also on helifreak and rcuniverse)

I have a problem when using throtle trim , running turbine helicopter and throttle trim is necessary for start up the turbine but , when I move throttle trim my swahsplate is starting to up/down jump ?
what can be the reason of this ?

Hello,

it seems there is wrong channel mapping in the radio or Spirit unit or you have some mixing configured in the radio.
Most likely it could be swashplate mix which should be turned off or set to H1 - Servo 90°.
Please take a look in the Diagnostic tab in the Spirit Settings.

Have you configured your unit according Setup Wizard?

thank you for reply ,

yes I did everything according manual , I ran through settings several times , for now it looks like I solved it and the reason was telemetry module from turbine engine , well maybe not telemetry itself but setting .
In the telemetry module you have to choose your radio slot you want to receive telemetry data and as a default it's set for slot number 8 , when I changed it for slot number one all problems are gone .
now wondering how this could interfere so much in my radio but it looks like the problem was in radio not in the Spirit unit
