RPM range

[jjrctech]

is there a rpm range where the boat pick up the most speed?? like between range 25,000-35,000

I did a test from 14,000 - 18,000rpm and did not see much of a speed change , is there like a sweet spot??

Thanks

The "like" sweet spot is full throttle. Or the highest rpm you can run given the voltage and motor kv. Heat builds easily when boats are run at anything less than WOT. No need to think about between this rpm and that rpm.

I do not understand your question. The "best" rpm will depend on the motor: too low and the motor overheats, too high and there is no usable power. The rpm has to be matched to the motor, voltage and the desired task - sport running, oval racing or SAW runs. For example a Neu 1515/1Y on 4S likes to run around 28,000-30,000 rpm. A BlackJack26 motor on 4S likes 21,000 to 23,000 rpm. Prop size has a big effect on motor rpm and boat performance too. What are you trying to do?

Fluid, as usual with a great response.
