i got a pro x chassis without a engine, had a 6 in it. that engine is toast and i don't have enough money to rebuild it. so i'm probly gonna take it apart and use spare parts for my edge x. i was pondering and pondering if i should put my 800 engine in it. but i don't have a pipe for it, just the edge chassis pipe. would that fit? idk what i should do. still pondering. another thing i have been thinking about doing was taking off the steering post from the pro and moving it to the edge.. would it work? any suggestions would be nice.
