which one should i get, im thinking about getting a trx right now because i wanna xc race some more if i got one it would be a kicker model. Then the yfz on the other hand i want to xc race with and they seem more easier to control, but not as reliable as the 450r. and the ltr is the last on my mind, i would just like one because they are super fast so i can get killed on it, and also race it lol.
