I recently bought a 1/16 grave digger from my son, plugged the battery in and fried the esc. I sent that in to Traxxas, they said its on backordered and no ETA. So my hobby shop letme purchuse a new one and wil let me return the one ill getin the mail who knows when, Now i installed the new one. Ran it times with and without the lipo, no problem, but on its 3rd use with the lipo it fried. Any ideas? Is this normal? Only had the car for 2 weeks.
