I also got stuck with the crappy F22, but im thinking about swapping in an h22. My question is do i need to get the complete package ? Will the axels from my f22 fit the new motor? Basically my question is, what are the neccessary items that i need to get, that without them the h22 wont run?? Im asking this because im running a little low on money and im thinking of a way to go around of getting the WHOLE package.
