RE: F3A World Scores
TimBle,
Its a weight thing, I think there power delivery would be great though.
You would also need to make them sound smooth and nice, not saying it can't be done but a standard DL style rat ta tat muffler wouldn't do at all and the nice cannisters add to the weight problem in a 2 metre.
I am actually about to try a new 36cc rear exhaust Chinese motor in an old airframe for interest sake and see what its like but I suspect the whole thing will be a tad porky.
