When I turn on the P3, the gimbal does nothing. No crazy dance or anything. If I move it side to side, it will emit a faint buzz. The camera is fine, and live view and recording works. There is a "yaw error" in the Go app. Recalibrating doesn't fix it.
The gimbal appears fine. No cracks...
What do you mean by "...maintain them at 40% charge..."?
Does this mean that if I'm not going to use them for awhile, I should only charge them up to 40% and then put them away?
