RE: BRIO Electric 10-size
914,
What ever it is it's got to be battery related. My CC Phoenix 35 was cutting out in knife-edge I had to program the auto voltage detect out because of that. No cutting out now the voltage cut off is manually set at 8.4 VDC.
Also what ever it is unless you previously crashed the motor, it cannot be the 480. My set up pulls over 280 watts @ 29 AMPS, take off at full throttle is like 15 feet may 16. Climbs straight up from dead stop to where you have to stop it because you cannot see it.
Most of my flying is at 1/2 throttle and that’s with a little 5-7 mph head wind. My Dualsky's work great battery temp when done with a 6.4 min flight is like 99 degrees maybe 100.
I'd toss them old Kokams before ya smoke em !
