RE: wild hare, LR-1 pylon racer
Here are my settings. I like using dual rates so I have a little more control on take off and landing if needed.
These are measured at the widest part of the control surface.
Low Rate
Rudder = 1/2 inch from neutral
Elevator = 3/16 inch from neutral (I think I may have tweaked this down just a smidgen. Might be closer to 5/32 inch.)
Ailerons = 5/32 inch from neutral
High Rate
Rudder = same as low
Elevator = 5/16 inch from neutral
Ailerons = 7/32 inch from neutral
When I calculated the Mean Aerodynamic Chord, I came out with a safe range of 2-3/8 inches to 3 inches from the leading edge at wing center figuring with 25% - 33%.
I have mine at 2-1/2 inches and it seems perfect to me there.
