Dear all
In a test flight, using OA parameters(vertical Bendy Ruler ) in our QUAD rotor Drone , 36 inches propellers, we had an excellent flight, since all the obstacles have been recognized.
In the last phase of the test flight, before the landing , we passed in Loiter Mode . On ground before disarm the drone made a movement like back and forth , we regained ALTITUDE and landed in second trial.
We expected that the sensors will not react due to obstacles or the ground ( ignore sensors below 1 m). We are trying to define the possible cause.
Assistance is welcomed.
