I just picked up a Snap-On Revo Brushless from a friend. He says he only ran it 2 or 3 times, it looks brand new. He says that it will only go about 35mph and only one of the batteries drains but both are plugged in. The car is all stock, including batteries.
I'm new to these cars, any idea why it may be doing that? Does he just have it plugged in wrong? Can you plug in the batteries the wrong way coming from the ESC? Maybe one of the batteries is just dead?
Any help would be appreciated!
