| I am testing an Joker for a friend
10S4P - old 8000 (red) flightpower Joker packs (two at 5S each). Full charge showing 42V with both packs connected together.
Actro 24-4 motor
Shulze 40-160 controller, the big pop tart unit
Straight line throttle curve at 55% gives 1700 headspeed
So here is the problem
Heli runs fine for about 3 or 4 minutes then motor starts surging and tail kicking. Land it, check pack voltage and it is just over 39V
I am assuming it is the battery not keeping up with the demand by the ESC, but in all my previous experiences, this problem just results in the headspeed decaying, not a surging from the ESC
Questions
Is this normal for a worn out battery and this controller?
Is something wrong with the controller?
Is it ok to run at 55%? Seems to me that the voltage and motor selection are mismatched, given I always try to run 90 or 95% on controllers with governor mode. Seems this motor should run on 8S
Thanks in advance for your replies.
