OK, I agree to no more spitting contest. Yes, you are correct with everything you said in your last post. I have never seen the snap problem with spoilers though, that may be a problem I haven't run across because my plane isn't exactly cutting adge. A good slow idle on a 4-stroke will indeed slow the airplane down plenty, but with 2-strokes sometimes even a slow idle isn't enough, and when reducing prop pitch isn't an option, well, that's when I came across the spoilers. I didn't really mean to sound as harsh as I came off in the past couple posts, I was tired, cranky, and dreading going to work in the morning, so apologize for that. I have no doubt the original poster has plenty enough information to make an educated decision as to what he wants to try first. I yield to the much bigger "propeller" your 4-stroke can turn... Any solution to this problem is a trade-off and pilot experience and ability should really be the determining factor.
