Post subject:  Set Trim function not working

Testing the "Set Trim" function, I have a channel assigned to it and can see the value change from 0 to 1 (off/on) in the channel mapping screen. I also have global gain setup as well. On the bench, I can set global gain to 0 (from the switch), add trim to a channel, activate Set Trim and nothing. No servo movement as indicated in the manual, or anything... Is this a bug or what?

I had hoped that since Spirit was great on helis, with no issues, I was expecting the same with the AERO, but so far if things arent working 100% on the bench, idk...

... and when doing a maiden flight, you can use trims directly in your transmitter to correct unwanted movement. After landing, activate the Set trim function. This function will save the trim values to the unit so that it will memorize current deflections. The activation is followed by a servo movement when successfull. The model must be completely without a motion to save it. ...

yeah, I got all that and did as it outlined and nothing. I can use trims on the tx, servos will move, but when activating the function and such, there is never any servo movement to indicate it has completed and was successfull.

The model must fly, the unit will recognize it. Activate the function only after the model has landed and calmed down.
The in-flight function of the model must be turned off.
If you turn on the function before turning on the model to the battery, the trims in the unit are reset to zero.

No sure why it wouldnt work on the bench for testing though.
