RE: goin crazy!
The R/C cars and trucks we have are by their very nature finicky pieces of machinery. No matter what car or truck you have, it's gonna need maintainence. If you plan to stick with the hobby and don't learn how to maintain it yourself, you'll be making trips at least 2 or 3 times a week to the LHS to pay them to do the work. That'll take money you could be buying upgraded parts or even another truck with, AT $10-$20/Hr for labor that'll add up fast. Please do yourself a favor and learn how to repair and maintain your truck. You'll save not only a lot of money but many headaches when you get all set to run and something decides to give out on you not even 2 minutes into your first tank that would take 5 minutes to fix instead of packing everything up and calling it a day bevause you have to go to the LHS and wait on someone to fix it for you.
It's really not that hard once you start doing it, and I doubt you'll find someone here that's been running these things more than a few months that hasn't had a screw or a nut fall off at some point. I lost my whole slipper clutch off my Stampede once because a mod I did wasn't quite right and the nut wasn't on far enough. It happens to the best of us; just part of the hobby and all you can do is pick up the pieces and double check it next time.
