As I had mentioned about a year ago, I thought there was an error in the rudder throw
specs. The manual states to set the rudder low-rate at 1/2", and the high-rate at 3/4". I thought this was much too low. The first time I flew mine I noticed I could not make a simple turn on the ground when taxying. When she was in the air, stall turns were all but impossible.
On subsequent flights I kept setting the rudder throws higher. My settings were at 1 3/4" low-rate, and 2" high-rate with 40% exponential. Stall turns were still sloppy.
Last night I opened up the rudder throws to 3 1/2" low-rate and 4" high-rate. I also reset the exponential to 45%. The 4" setting is the highest setting you can achieve without the rudder smacking the elevators.
I took her out today and noticed my stall turns are now a lot sharper.
Ground taxying is also much better.
My CG is set at the high end of the recommended specs and a little tail heavy at 3 7/8".
