I'd bet radio interferene. As you go up in voltage there is more electricity so more electrical noise. To diagnose it, move your reciever as far away from everything as possible, andtry again. I just had to learn this the hard way.

New motor 1200 x 56 mm rather than the 50x1500 and the trouble is back again. Exact same trouble when using over 100 ft range.

Now I see sparks intermittently inside the rear of the motor on the bench test . I don't know much about bl motors, but that can't be normal, right? Funny thing is it will do it when starting up , but when running WOT on a bench it'll be perfect with no sparks.

I put the set-up into my slash and it works perfectly. Will use MMM in this e-maxx instead.

I put the MMM in the maxx and it runs perfect with the small 1200kv motor and it runs perfect with my largest motor too. I'm concluding that the motor was pulling voltage down and causing thr rx to run on low voltage?
