To be honest the trainer type of planes I've been flying are getting so easy to fly I don't really do much to them other than setting the linkage up correctly and getting the right CG. I haven't really gotten to the point where I worry much about adverse yaw, incidence and thrust angles.
I imagine those are things I need to learn more about as I get further into this hobby. I've been in the hobby about a year now and I am still learning. I live by a lake where a club has a site and I went there and flew a Turbo Timber with floats and enjoyed that type of flying. When the Beaver was available at a swap meet I picked it up thinking one day I could put floats on it. So I'm basically still learning. I'm not opposed to buying nice digital servos...I just need to learn the difference between nice and average, etc.
