Default RE: CG and Control Throws

raynman:

By the way, the wing loading of 26 oz/sq ft is in the normal range for your size airplane - not too heavy, not too light - so you're OK here.

Regarding control throws, I suggest you set them up by angles to determine the measured inches of deflection. To set up deflection by inches without regard to control surface width could be very misleading; for example, a 1/2" deflection measured on a 1 1/2" control surface width would be about 20 degrees, whereas a 1/2" deflectiion on a 3" control surface width would be less than 10 degrees.

My suggestion would be 20 degrees for aileron and elevator, and 25 degrees for rudder at high rates. Low rates would be ABOUT 1/3 lower, like 13 for aileron and elevator , and 16 for rudder. To get the deflection in inches, you would have to draw the angle and measure the deflection at whatever the control width is. ( Hope I'm not confusing you)
