Well I am sure I am not the first to think about having one of those little screaming car engines in a plane. Well the problem is that they spin +/- 40k rpm's. Has anyone ever thought about putting a 3:1 gear or belt reduction unit on one? Yes I know there would be a little bit of a weight gain but those LITTLE engines put out some crasy power at those rpm's.

Here are some specks from some .21 size car engine I was looking at on horizons site.

1. rpm's = 40,000
2. hp= 3.1

WOW

Please just give me your thoughts.

Oh and by the way with a prop and a gear reduction they wouldn't be quite as tempormental.
