Yesterday I did some testflights with the tick. Before I changed 2 motor mounts to get fixed with platic rivets to let the motors turn without vibrations under heavy load. While flying I realized after a few minutes bad behaviours of the UAV. I tried to go for a landing but it was too late. The aircraft started to make a flipover and crashed bottoms up in the grass. The gimbal was smashed out of the connectors, one propeller was missing additionally the nut too. This morning I checked again the crash area. I recovered some parts which I did not saw yesterday night when it was getting dark outside. In Germany the sunset at this time is at 9:30pm around. So the flashlight gave me no honor to get all the parts yesterday. This morning 3 of the gimbal bumpers, a smashed propeller and the prop nut appeared suddenly. Today I will check if more parts and wires are destroyed.
The reason for this is the gimbal. I don´t know why but different forums say that other pilots had same experience with this gimbal. The control board getting really hot while flying. Maybe there is some need of cooling for it to work correctly.
I still want to order different batteries to test around but the german Post employees are in labour strike for the last few weeks. Packages are stuck in their office and it is hard to get them at these days.
