Hope someone more clever than me can figure this out.
My setup is this:
SSS 56104 500kv motor + 5:1 Neugart PLE40 gear
Flipsky 200A FSESC
Flying Rodeo propeller
Correct me if I am wrong please, but the calculated the max. erpm for my setup is:
12S x 4.2V x 500kv x 6poles = 151.200 erpm (Max. battery cell voltage 4.2V)
12S x 3.9V x 500kv x 6poles = 140.000 erpm (Battery voltage 3.9V under load)
But the max. erpm in the VESC is 100.000 erpm, it cannot but set higher… So am I missing the upper 40.000 to 50.000 erpm or will propeller never reach that many RPM in the water?
100.000 erpm / 6 (poles) / 5 (gear) = 3.300 rpm for propeller
140.000 erpm / 6 (poles) / 5 (gear) = 4.600 rpm for propeller
