I have a carbon core frame with 40 opto esc tiger motor and mn 3520kv tiger motors with carbon 17 inch props. 2 X 10.0000 mh 6 cell batteries. 6kgr.
My first flight problem was i take off on 5-6 meters by mistake i change in atti mode ( have gps -atti-atti) and the craft started to goes up.Immediatelly return to gps mode. The aircraft started to take angles. the worst of all when i tried to take it down didnt go down. When tried fail safe mode just fell down.

My questions.
a.Is there a chance to be so light the drone (6kgr)  for my motors so not come down (landing) ? (50% thrust of motors is 8kgr) .A2 controller -> Motor idle was on low.
