Great, I've figured this one out previously. What I really need is a power predictor for home made BL rewinds I've made for my Eflite Blade CP2, that does this and also has a airfoil profile lift to AoA plotter that calculates needed rpm/power (watts) to angle of attack for hover and climb.

Sort of a Motor Drive Calculator for helis

I guess this is asking for too much?

Thanks anyway it's a good, simple, calculation helper.

nice work. Ive been looking for a way to find head speed and see what different sized pinions will have on it.

Not a problem. We'll get right on it. Uh...let's see now. E=mc to the ... uh. Ok.
I think I got it.

Doesn't really calculate for smaller CP helis like the EFlite CP2.. No weight, no rotor diameter, no Lipoly mAh capacity, no calculation of lift for various types of blade airfoil shapes, ( I made my own semi flat bottomed blades with a Eppler 205 profile.) no length of blade, doesn't take into account small motors..

Kinda limited...
