Hey Houston, cool thread!

I have an OS Vspec .21 in my truggy that I know is capable of HAULIN.

Right now, it seems to have a great tune (good idle, top and bottom both come on strong but motor isnt getting hot). For whatever reason, I keep fouling out, at random.

Last time I ran the motor I went through a center and rear diff, so the motor was working very, very hard before I pulled her off. I believe we temped her at like 300*.

Since then I put new clutch shoes in, rebuilt the diff's and put the motor back in. Now I can't get her to stay running for the life of me. She will sit there and idle, but seems to die at random.

I am completely new to the RC car/Nitro scene, and I'm wondering what the first steps I should do.
