15cc???? bloomin ech Geoff? i was looking at a 3.5 nitro engine, it produces well over a horsepower at 28,000rpm.

again, was joking about gearing down, you would have to or youd smoke your clutch, experience of alloy wheels talking there, spinning heavy disks wont work too well unless you gear it down at least initially..

Would very much like to see Mike show up with one of these as Ive heard hes plenty of experience with them is his bellychoppers.
