roll coupling

[Koenig, Tom]

Steve..I have a copy of this article ( no trim chart-just written), but it is early 70's. Would you like this one ( is there another one??)

I will scan it for you, and anyone else that wants it?

Tom

 Thanks guys that's what I thought. Bending a carbon tube may be tricky LOL. Thats one reason I have ask more than once looking for the Jim Kirkland trim chart from the late 70"s.

Dihedral.  It's ALL about the dihedral...  To much and you get pro-verse coupling, too little and you'll get adverse coupling. 



Ever flown the old "Contender" kit??  Zero dihedral in the wing...push hard right rudder and make a nicely banked left turn....lol

 I was doing some changes to my plane the other day moved CG back a little tested with a little more incedence, and no matter what I done it requires aileron mix with rudder. I haven't found anything that explains what needs to be changed to fix this, the mix is 12% and 15%.

 Any thoughts out there?
