On the firsts flights of my new motor, when the batts (3s lipos) aproach to 11.0 v the motor revs down a lot in somewhat about 5 secs, seems to fail mantaining power
My setup is a himax 2808 980 BP10A controler (running cool) and GWS 1000Mah lipos on a 11x 3,8 APC prop; I have measured 8,6 amps at full power and full batts, would it be to much prop for the battery?
Couriously I have measured 8,8 amps on a gws 10x4,7prop so, I`m a little confused because I have expected less draw... I resist the idea to prop down to a 9 x 4,7 it would be a significant power loss

Any comments will be apreciated
