I have ordered my Raider 150 amp ESC. But I am on the fence for what motor to get. Leopard, SSS, Geforce (cheap, and will buy 2 for a later twin system), or the Castle 1515B 2200KV. These are my top choices money wise. Want to keep it under $80
on to the title of post. I have rather unusual question about power systems. I am wondering about the KV VS voltage, and size of motor. I know that If I get a sizable motor, I can prop up a bit.
But what about a higher KV, and run 2-2S batteries in parallel with a 4400KV 3660, and a relatively mild prop?? parallel doubles AMPS and run time. 50 amps constant capable batteries 7000MAH, gives 14,000MAH and 100 amps current.
example
2200 KV @ 16.4V's 36,080 RPM free spin
4300-4400KV 36,120 to 36,960 RPM free spin. load of boat and prop will obviously drop this close to roughly 20,000 rpm
Mathematically it adds up, but I am wondering if it has been tried before??
Thanks
