Battery. Shorted. ESC fried. Red to negative, Black to positive, right?
Forgot to plug in battery and couldn't figure out what was wrong with it for 10 minutes.......
Didn't plug in a throttle servo and it tore down my driveway into a drain.
Didn't turn on receiver, and again, it tore down my driveway into a drain.
I was trying to do a full speed run, when I heard a VROOM! POP! louder VROOM! Dead. I walk up there to see the pipe, and all of the fuel lines disconnected. Oops, I didn't put them on correctly.
