Did you get a HP read before fou seized? It would be nice to know what kind of power did your Homemade exhaust made with a ported Malossi 70cc Sport.

Why u don't drive with a piston, with one piston spring?

The project looks funny, but i don't want to drive on that mad crazy machine

haha

you should try mixing your fuel with av gas if you can get your hands on it.

hi, nice project !

but i see you're problem with the nitro, you'l need to use a liquid cooled cilinder and maybe retard youre ignition.

i did some tests a few years ago with a honda camino racing engine, it was a 80cc if i'm correct with everythin on it.
i mixed up nitro/methane with 98 unleaded(don't know the ratio anymore)
the cilinder could hold the power but the cranckshaft did'nt

i managed to squeeze just over 90(real)km/h out of that engine without changing the final ratio

believe me that 's just terrifying when u are driving those speeds with a camino even tough it was fully adjusted for racing
