I build a Quad with F450 frame and 2212 920kv motors (readytosky).
APM2.8 is the FC and 30A Simonk ESC.
Being my first one (I started with KK2.1 and now APM), my quad knocks-off frequently. Either to a remote tree or while landing.
My observation and problem is, with almost every minor crash also, ESC stops working.
Means, motor starts stuttering and I re-calibrate ESCs and still status is same.
I replace ESC and it's normal. I have changed 6 ESCs till now.
My query is,
Are ESCs so sensitive?
or there is something wrong with connections or which I donno?
Do I need to have some additional protection around it (I am using cable ties at both ends, where 3 & 2 wires start)
I bought couple of them from Chinese source (Aliexpress)
Then I got from one Indian source Robu.in.
Later I got from another source in India Sunrobotics.com
Issue remains same.
Thanks
