[NSRCA-discussion] aero question

[Jerry Stebbins]

Jason, what plane, and what is the rudder shape, is it counter balanced?
Rake should give you more of a pitch couple--probably pretty small. I have 
tried 1/2 inch and saw nothing, but was not looking at your conditions. more 
at pitch effects.
Might be the upper section of the rudder is somehow seeing less flow at high 
angles, and therefore being less effective--that would become a right roll 
couple as you are seeing. --- might try taping on more area on top.
