You seem to have had the same trouble I had...when the fail safe should have kicked in...it did the opposite.Some how mine switched to reverse as I was mashing the gas...and buddy when it hit,the sparks flew and the truck quit...for the 3rd time(broken spur gears) I hope CEN Racing is going to help.I really like this awesome truck and was hoping to turn my friends "onto it".Hey if you have any info or know where I can get better gears ,that I have been hearing about...let me know.Thanks,Mark [email protected]
