IMHO......A V8 in a '69 beetle might work, but why?

With a 5 cell batt under the tank and a Saito .91 my SW balances 1/2 inch behind recomended, and that's cool for me. I don't think this plane will anything well but loops, barrel rolls, and land, and the .91 does that well! You could overpower a similar sized areobat with that motor and really have a ball!!!

But others may dissagree. Personally, I just love to watch this baby land on a still evening. I've used many tanks of fuel just landing over and over!
