I think we need gas-powered fans for next year... if it can break it will
My team (I actually) broke one of those flexshaft thingys this year during our practice runs at the NYC regional... we had to go over to the machine shop and make new ones out of alluminum. Its funny, i break somthing and eveyrone is happy for a change.
Back to the subject, I actually was present for the burn-out of a victor fan... it didn't really speed up all that much, just got hot and died.
The big cooling fans could take it a bit better.
