Speed Calculator

[BrianG]

What I usually do is get a best-case speed and a worst-case speed.

To get the best-case speed, I use 4.2v/cell for the lipo and the maximum ballooning I think would be possible. Also, if I know it, I also use the unloaded motor kv value.

To get the worst-case speed, I use 3.3v/cell for lipo and no ballooning. Again, if known, I use the loaded motor kv value.

Either case will be wrong, but you know your speed has to be somewhere in the middle, probably a little towards the best-case side.
