Spirit System

Hi All;
I have a Spirit Pro on TREX 450, been flying it fine for about a month. Now when powering up at half throttle the collective pitch jumps between negative and existing transmitter pitch ?

Hi,

you can verify Flight log in the unit. If there is something saved then swashplate pitch pump during initialization is different.

Thanks for the response...any specific details I need to look for in the log files ?

You can check if you will see a log from "previous flight".
