Its very easy to do. The capacitor in the middle of the victor is electrolyitic which blows up if you hook the power up backwards or hook the power up to the motor. Its rather quite spectacular. Not to mention the fact that the Mosfets themselves are very fragile to static shocks.

I did that once. Made the machine shop smell real bad, as Dillon probably remembers...

Sorry to tell you, but that was only one victor.

We've smoked a total of three in 6 years. Always painful.

haha.....we blew 3 victors while practicing with our old equipment...lol...it was pretty funny.....ya....

Our teams only blew one, two years ago we had just finished the wiring and were beginning to test the programming. One started sparking and smoking, we had a laugh... and a bit of a fright luckly we had two extra. I cant rember what we figured made it die, but I think it was metal shavings shorting the capacitor.

We've blown a few but the worst situation was a demonstration to some elementary school students and the robot drove at them going full speed, but of course our amazing electrical guy, R2, knew something was wrong and tackled the robot,literally, and turned it off. That was pretty intense.

I actually hooked a Victor up backwards last year. When we turned the robot on i heard a "WHRR-CLICK, WHRR-CLICK" noise. Our breakers tripped before any damage was done, so we were lucky. However, this year as a training exercise, we let our rookies take apart last year's bot. One of the rookies used a power drill with a Phillps bit in it and tightened the screws so tight that they broke off at the head. That was bad.
