SSS 500kv 56104 - Best reduction for a 7 1/4 3-blade alu prop?


#1

If this is advisable to run at full motor speed to save on ESC, would 8:1 be an advisable reduction versus 6:1 or 4:1 ?

500kv * 44.4v = 22 200 RPM
22 200 RPM / 8 = 2 775 RPM

Thanks

Not with that motor. You want to have a prop rpm of at least 3000.

3000 is nice on load so maybe 3600rpm with 56 and 4000 with a 40mm in the air
