The chicken or the egg?
Popped the 3s in the Stampede and took off up the road. Blasted up the street, back down and up the side street. As I hit the brakes it made an odd noise, kind of like a loose slipper clutch. Turned around and hit the gas, it made the same noise as it rocketed up to speed then instantly flipped over forwards and turtled on it's back. No forward, no reverse, no steering and when I checked, no lights on the esc.
Blew the magnet into three parts inside the motor and dropped a cell on the lipo. Did the battery fry and take out the motor, or the motor dying take out the battery. Or complete coincidence that both happened at the exact same time?
