Just bought a new Traxxas ralley vxl ralley. I bougt my son the ken block. I bought the regular ralley. First time i take mine out to drive. It is really really slow. i have checked programing and everything is right. I am not in training mode. I can hold the throttle completely wide open and i barley moves then it slows and speeds up slows and speeds up never reaching a good speed. I have made contact with traxxas but nothing seems to work. I am new to r/c so i need help. Is it the esc or link i am looking to replacing both is this a good idea. i dont think it could be the motor or is it. I dont want to drop another 200 just to figure it out does anyone have any ideas. i really want to race my son with his but dang mine is junk right now. It is brand new from hoppy shop on line so dont want to hassle with sending it back so forth. i just want it to run.
