tim,
wow! i woulda thought the boat would slow down a bunch, guess not. i'm gonna be making my first .21 soon, maybe a gearbox is something to think about...
hammer,
it seems like it would be easier to use a standard header and cowl than install a gearbox...oh well, maybe it's cuz im american!! ;D
ian,
aha! i knew it! what manufacturer makes a 2-cylinder nitro? i've never heard of one .....21 geared sounds cool, i'll probably be running one of hammer's OS .21s to get used to it....i wonder if i could race competetively with it by gearing?? i was thinking more of gearing to higher RPM, and using a small prop.
