Speedracer, I was giving advice to a beginner, at least that's how his post reads. If you want to give him lessons on aileron differential, adverse yaw, climb and descent in relation to throttle, adverse torque on power up, etc.etc.etc. be my guest. My post was based on a beginner's perspective. You and I know quite well all those parameter's and what to do with them, he may not yet. I'll be waiting for your book.
