Calibration problem

My problems went away when I change recievers from a Spektrum SR3300t (telemetry) to a stock standard sr300, seems some recievers arent as picky

Cheers

Hmm....I'm using a Spektrum DSM Pro receiver....wonder if that has anything to do with it, although I was using the normal grey spektrum rx with the MMM that wouldn't play ball until the FW was rolled back to V1.21.

Using the MM then it has no switch as it's been removed, would that have an impact on this perhaps?

In the SW I even dropped the arming time to 5 seconds hoping that might help too, no joy...
