RE: 250cc Briggs & Stratton for large scale planes?
Seems like after you took off all that extra you wouldnt need it would lighten it up quite a bit, I mean Im sure it would still be a bit on the heavy side. As far as power gos somehow those mower racing boys get lots of power out of them. I know you could get more just playing with govenor and maybe exaust. But you guys are right about vibration, after watcing that vid that Gkamysz post looked like it was gonna shake apart. Defanatley have to come up with some type of good rubber mounted system. But not sure if rubber mounts allowing engine to shake around there for prop shaking around would disturbe flight.
