Vibration, gimbal unresponsive...

oikonomoupetros · Oct 12, 2019

Greetings guys, drone had a fall.
Since then starts fine, takes off fine, but when going above 10km/hour the gimbal shakes very badly and it is unresponsive. Once I stop accelerating it recovers and responds well.
Gimbal is in place , propellers are brand new.
Could it be just an imu issue or is there anything more I need to check?

How is the vibration plate and dampers (rubber bands)? Have any of the bands (I believe there are 4) come lose or broken?

I seem to recall that even if the bands are attached, the vibration plate can shift out of place.

I don't like the looks of the spacing in the pitch motor. The spacing should be even.

Who do these look like? Must I open it?

Should be able to see the bands, can see parts of 2 bands in the first pic above there . . . might need a small screwdriver to put under the several loops, and gently test to see if any sides are broken.

The damage looks like it had a pretty good knock . . . you said "had a fall", as in crash or off a table etc ?
If a crash, it's more likely to suffer worse of a shock, there could be an issue with part of the gimbal itself sustaining damage, or a cracked plate, damaged ribbon, possibly other things.

Hope you can get it sorted.

A crash from 20 meters after hitting a tree and landing in concrete.

What do others think about the spacing in the pitch motor? Looks uneven to me in closeup of first picture meaning damage.

Found this video. Only for a few seconds towards the end can you see the bands in the back. But I chose this video because it brings up another possibility: gimbal vibration board tabs may be out of place.

Yes looks that way to me too. While possible it's just the angle of the shot as taken, holding mine viewing it from the same angle? doesn't so much as hint at an uneven gap at that point like seen in his first image.

A straight on picture of it would tell the tale.
