Dom I'm somewhat new to the RC world. I had a nitro truck along time ago but it wasn't anything like what I have now. I was actually gifted a revo 3.3 with a hole bunch of extras. Long story but anyways I was running it the other night and out of no where out just stopped. So I tried restarting it and it wouldn't budge. Tore the engine apart and found that I busted the Con rod and put a hole in the piston. Did a bunch of research and found that the picco .26 red dot seems like my best engine. But what I need help with is what else do I need. I'm a mechanic so engines come second nature to me but I have been reading a lot of articles and some people are talking about needing parts I've never heard of. Any help would be greatly appreciated. And if you recommend a different motor I'm open for sugestions to. This is a hobby I would like to get into with my son. Tha k you.
