After a few minutes flight time with AQ M4 the copter sets strongly to the side and drifts away. The drift is too fast to control against. The horizontal accuracy is about 1.5. The problem sometimes occurs after 15 minutes, sometimes after 8 minutes.
On the picture can be seen that the M4 is about 1cm under the shield of the antenna.
In normal flight mode this behavior is never occurred.
Has anyone experienced a similar case?
