Default Re: Servo torque required

I'm thinking the calculator may be flawed. At least enough to say that counterbalances shouldnt matter.
This is what I plugged in for a .60 sized profile plane I have. I'm currently flying the crap out of it with 90 oz servos.
Measurement
US Standard
Metric
Max Speed 60 mph
Control Surface Chord (front to back) 26 inches
Control Surface Length 4.5 inches
Control Surface Max Deflection (from center) 60degrees
Servo Max Deflection (from center) 60degrees
Servo Torque required 1321.029oz-inControl Deflection at max torque 60degrees

Crap. You are right. That changed it to 228.64 in oz. probably a little overkill but makes more sense than before
