I would have to agree with Kahlog. A gas engine would of course, work. CG problem could easily be countered by a little ballast at the tail. Vibration may be a problem with these cheap polyester resin fuses though.

The nose over problem could be eliminated by putting the LG in the correct scale location. along with correct scale rake

I would use gas but the smell of gas would bug me in my shop. My garden shed is bad enough. I have tried "white gas" (no smell really) in a weedwacker, but its engine life was cut short. Maybe not enough oil.
