MGM Controller, brakes sometimes.

It sounds like you need to send them for the software updates.
I have version 2.31 on mine so i'm going to send it for the update.
The problem i have is not when lifting off (i have drag brake off,and freewheel on).The problem is it brakes when you blip the throttle/apply a light throttle whilst coasting.It seems to try to reduce the motor RPMs to the level of the throttle input,so if you apply a light throttle it will brake violently.
If you set the range of throttle neutral zone high it helps.I use a one-way bearing to get around the problem in the mean time,it's the only way it can be used with a lehner motor.
