Motor voltage

[BrianG]

It is important to add that you will get less amps with more voltage IF the motor resistance is higher. And the 2Y does have higher resistance than the 1Y.

The whole amps question is moot really. So much depends on gearing, weight, drag, etc that is all but impossible to estimate. When selecting a motor, shoot for ~40k rpm for the better motors and ~35k for the Wanderers/Feigaos/etc. Then, just divide that max rpm by the motor kv to get the ideal voltage to run.

Not to hijack this thread but do you think the feigao 380xl motors could handle 4s or 5s. It is a good length and around 2900kv, so 4s would most likely be the maxx I would try.

Nice info to hear Brian. That makes me feel better . . . when I run your calcs for the 40k rpms, my Neu 1515 2700kv comes out to 14.8v and that's what I'm running.
