I have a speed 600 motor and an 8x4 prop, with a speed sontroller that is rated at 8.4V. the problem is the speed controller has BEC and cuts out at 5.6V. The current battery pack can't coupe and and drops its voltage to low on full throttle. What type of batter pack would I need so I could draw a good current and keep the voltage up?
Thanks,
Ross.
