Well, I took BOB to Robodojo, it had one hit from a spinner and the esc in it died. No more sabertooth esc, also this is the only damage done to its body.

The cause of death, part of the exposed wires where it goes in to the esc touched each other when that spinner hit it.

To do list for next time.
Better esc
Thinner wires
Make the body about 2cm longer, the battey almost didn't fit.
