9x5 graupners defo the way to go! Imoa.
I reckon them 900kv motors could be good for 4s with the dji 1038 props? The dji std motors get a little warm! Ok on 3s though.
Maybe you two need to step into my garage for a crash course
I like the way I have my 9xr setup, the only thing I'm missing is course lock.
It has on my three position switch- fail safe (rth), attitude and gps.
On one of the two way switches - home lock on or off.
Then gimbal tilt control on one of the pots/knobs.
Then obviously when switching tx off fail safe kicks in (rth).
Sherbs has a good setup that includes course lock but think he has to toggle two switches to access fail safe?
