? Engine swap Rotax 100 for 80

[DesertFox4]

Gary , I think you'll find the majority of Rotax 912/912S equipped model 4's have 3 blade props. Check out the Photo album directory under model 4's and you probably will discover that very quickly. Ivo props and Warp props probably make up the vast majority. GSC (wooden) props are still used but less and less.

Hey Gary, The model 4 with the 80horse 912 still has an abundance of power. If you get a chance to fly one, you may feel you really don't need more power. Look at the Jimmy Franklin videos on u-tube and see what he did with 80hp. Horsepower is like money, we never have enough.
