Dunno why you’d bother with the complexity of something like that for tiny power amounts. When you could get any decent sized engine to put down MUCH more. Not to mention you can run any 4 stroke on nitro pretty easily. Just need to be able to supply the fuel and have internals strong enough to handle the bang.
Also running a fuel that is $60-90 per gallon is pretty silly for those power levels
That said Integza did exactly what your talking about on a bike. It worked very poorly.
