Yeah, the KV-2 was designed to take a beating and not be overly scale. I have no issues handing the controller to a kid under the age of 10 because I don't think they could actually break it.

There are some internal pics of the hull after I rewired it. It has 50A breakers on the motors since they stall at over 100A. It's wired to accept two 6S 5000mah LiPo batteries wired in parallel to give it 10AH total capacity. I've tested it with the TCB controller, but it didn't like the Vantec ESC I'm using. I may end up testing it with some IFI Victors to see if that works with the TCB. Or forgo that and just add a sound system to it.
