Lots of good, interesting posts.
For those who thought I was complaining, please don't read that into my initial post.
I could care less what people put in their planes. I just have never had the desire to do so, but I wouldn't complain, piss or moan about anyone who chooses to do so.
As many have stated, we do the things we do because we have fun doing them and because we can!
I have a BN Citabria that originally had a Fox .78 R/C engine in it. This plane has a
nine foot wing span. It can, and did, fly with it but I'm retrofitting it with an O.S. 1.20, so I guess I am "overpowering" it by quite a bit (according to BN, anyway!)
Have fun. Life's too short not to enjoy it.
