Hi All,
After lots of vertical lines, and inside loops, I have set the rudder trim and the result is not good. The lower tip of the rudder counterbalance is 3/16" offcenter to the vertical fin, in a Left rudder direction. I've gone through this rudder trim trial for several flights, not believeing my eyes that this was necessary, but it is. When pushing from inverted flight to an upline, a lot of right rudder is needed to hold the line through the radius. I do believe I can see some Right rudder direction molded into the vertical fin.
Has anyone else done loop tracking, and needed a bunch of left rudder? Possibly an effect of the E-22x12???
Thanks,
Jim W.
Jim,
My Mark 1 eyeball says that the top of the vertical fin is offset. If you then line up the counter balance on the rudder to the top of the fin you will indeed have right rudder. I split the top of the fin and then attempted to straighten it out when I installed the rudder post. Hopefully it will not be a problem.
Did you offset the wings to compensate for the slight twist in them? I went crazy trying to set the incidence with differences if I measured inboard or at the tips. A good reason to plan on adjustment after flying.
