Hi,

after I crashed my Spark at first I thought it works flawlessly afterwards. But today I tried to fly.
When hovering in place it can't really hold the position, it's drifting up down / left right for about 0.3m randomly. I can't take still shots and recordings anymore
I looked at the sensor states, everything seems to be fine... I recalibrated the compass, havn't the IMU yet.
Any ideas beside "send it in for repairs"?

Calibrate the IMU for sure and take off from a dead level surface in an area with little to no interference on a well lit day. If the problem persists then you may have to return it to DJI for diagnostics and potential repair.

After crashing from 400+m, your only real option is to send it in. The kinetic energy from the crash has to go somewhere, if the outside is undamaged, the damage will be internal. Considering the circuitry inside is delicate, somethings got to be damaged

At what height is this happening? Sensors can cause AC to go up and down in bad light conditions or no textured surfaces, can you check from out of sensor range.
Doing Imu will not do any harm so it’s worth a try, because your having problem with Camera as well if Imu does not work then I would send it in to be repaired.

Will calibrate and retry. Most probably there is internal damage as already stated.. I hoped that the internal diagnostics would give me some errors if there is any damage.

That happened on 5m height. It was sunny outside, the ground was tarmac.

Yeah well I kind of taught your problems may be a bit more than that. Hopefully if you send in your spark it won’t cost to much, but at least you will know it’s been fixed properly.
Good luck.

Please also calibrate the IMU, that is an important element for the drone to maintain it's altitude, and make sure that you fly the drone in a great environment, so it can either use GPS or VPS to hover. If the drone still drifts, I would really advise you to send it back for the safety of flight.
