My Spark fly's but is twitchy
If you rotate it, it carries on on its own and then fly's off and crashes. This happens every time. Has any one got any ideas ???

have you changed the location, calibrated compass and IMU, reflashed the firmware with assistant 2?

But seems you are lucky.
If it chrashes EVERY time, but you still can fly it?

Upload a / some flight record/s and link it to this topic:

Calibrate IMU and Compass, be aware of magnetic interference. as told update the firmwares.

Hi, thank you for bringing this query for us. We're sorry that you are having a trouble with your DJI Spark. May you please send us a video sample showing the problem for us to help you further? Also, did you receive any error message in the app? You may try to calibrate the IMU for the stability of the aircraft. If there would be some instances that you can fly in a different location to see if the problem persists? Please keep us posted. Thank you!

Thank you for your help. It was very useful and has done the trick I think. fingers crossed.
