I think you pretty much found the #1 site for support. There are a ton of good guys and gals(I think there are some girls here) eager to answer your questions. You can also try www.maxxtraxx.com it's more oriented to the racer, or go to www.traxxas.com they have a forum also. The traxxas web forum seems to move at a quick pace and you only get a couple of replies, here I always get a ton of feedback, and great information.

As for hop-ups there are a ton of websites. Let us know what you are looking for and we can probably point you in the right direction, if not answer it ourselves.

Welcome to the world of T Maxxes. You will have a ton of fun I guarantee it. I bought mine about 2 months ago and have been loving every minute of it. I just got a bunch of new hop-ups and will be busy installing them tonight. Woohooo!!! I am excited

Like I said post just about anything and you will get an answer. Happy Maxxin'!!!
