Calling all you brains...

I am going to make a servo size calculator web page. Anyone know the formula?

Needs to include: plane wieght, speed, and control surface cord and length.

just got this from http://www.csd.net/~cgadd/eflight/ca...vo.htm#formula

Torque(oz-in) = 8.5E-6 * ( C2 V2 L sin(S1) tan(S1) / tan(S2)]

Where:
C = Control surface chord in cm
L = Control surface length in cm
V = Speed in MPH
S1 = Max control surface deflection in degrees
S2 = Max servo deflection in degrees
