Also cant forget about amp draw...

Lipos are rated in terms of there C rating. The higher the C rating, the more amps that pack can produce under high stress conditions.

say for example you want a motor that will spin about 30,000 rpms which is a good starting point.

If you use a 4s pack with a 2200 kv motor you'll spin about 32,560.


if you want something comparable to 30,000 rpms on a 5s setup you'd have to run about 2000 KV motor

The RPMs in the end will be about the same but using the higher voltage of a 5s pack will yeild less amps drawn and when less amps are drawn... less heat is generated.

so in short, you can get a setup for any RPM range you want, it really depends how much you want to spend on a speed control, that decides it imo...

High voltage Speed controlls (anything over 5s ) are usually expensive and exotic... aka mgm

Lower voltage speed controlls are reasonable but you usually generate considerable heat when using them... aka mamba max
