I agree... rebuild it. I just blew my first board and picked up a plastic gear S&S Tiger from Raidentech planning on using the new one and keeping the old one as a parts tank - right! Didn't work out quite that way. I just ordered/received all the parts I need to get it back up and running and now I have two tanks!

It's a good way to learn how they work and how the wiring is run, etc. so it will be good experience for when an accident occurs. Plus, the satisfaction and sense of accomplishment that comes when you get her back to life. You know, that warm feeling a guy gets when he cuts some wires, heats up a little solder, pushes the ignition button and fires up four pounds of mechanized death and everything works... sorry, got a little carried away there - you know what I mean!
