I bought a duratrax overdrive st a couple of years a go and have had nothing but problems with it. I wanted to know if any one would know where to start fixing everything that is wrong with it. I took it to al's hobbies to have one of their mechanics fix the problems that i had, but all he did was screw it up even more. The problems that i had were that it doesnt want to start without having to hold the throttle wide open, and it isnt shifting into second gear, and just overreving. So if any one knows how i should go about trying to fix it, please reply.

-Thank You
