My crawler was working great, then one day it started to act up, glitching like crazy!!! It works fine and then all of a sudden it starts to glitch, then it simply would not move! The steering would not work nor the motor. I picked it up to see what was wrong and it started to work again!!! Go figure!!! Then when I started to pull a hill, the motor started to glitch, making it move forward and backward about 2 inches each way! Picked it up and it quit glitching! I made sure that the crystals were in properly and that the antenna was in firmly and also sprayed some contact cleaner on everything but I still get some glitching every now and then. I then checked to see if my esc and steering servo leads were in properly in the receiver. It still does it every now and then! Anyone have any answers for me?

Thanks, Uncle Sky
