If you want results, do as BiggTony suggested and go to rcdiscuss. Thats where they take care of problems. I'm one of the people who've dealt with them for years with no problems. I also had good luck with Matomart. Unfortunately, their shipping can be steep to the U.S.. On the other hand, I've had very bad luck with the two U.S. vendors who are so highly praised on this forum. I paid $180 for a new tank and got a used POS that never has worked. I've since given up on RC tanks due to a lack of reliable parts sources. I run them occasionaly, but when they break, they're trash.
