I am totally new to rc, but I know I want a nitro rc monster truck. I am prepared to work on it, thats part of the fun to me. I know I'll probably smack alot of stuff at first. The more I have learned about these trucks it seems rev dont matter that much. I noticed alot of people on here are doing away with reverse on their trucks. I have considered the Savage but it seems like the Monster GT is just as good. I do like the aftermarket support for each of those trucks. I dont mind buying parts on line and waiting thats one reason I am thinking about the TNX. When something breaks I am so far from the hobby shop I might as well just order it. How big an eng can a TNX handle if someone wanted to upgrade one?
