Thrust Angle
 
To start, I've been flying IMAC for a couple years now and am in Intermediate. I'm really careful setting airplanes up (ask my wife;)) but I've never really hunkered down and tried to totally perfect an airplane's setup, but I think it's time I do so.

I've started thinking about some of the corrections that I make when I fly, and wonder if a little better setup would minimize them. One of the big ones is adding left rudder in an outside push (climb)... like an outside cuban, or the teardrop. I have my plane tracking straight on uplines, but I do have a small amount of right rudder trim in. I am wondering if adding right thrust and removing the trim will reduce the left rudder required in the push or increase the left rudder required?

I am assuming that I will always need some left rudder due to P-factor when inverted... just want to know how much is normal.

Thanks.

RE: Thrust Angle
 
Nevermind. I finally had a calm day and did some tinkering... got her figured out. I think most of what I was feeling was from the excessive wind around here lately. I also tried a little throttle-rudder mix... feeds in a slight amount of left rudder at lower throttle settings (per Peter Goldsmith's article). Seems to track really straight now.
