Blown Victors - WHY?

[Rickertsen2]

Are you sure the victors are really bad? in my experience about 85% of speed controller issues are really PWM cable issues. What are the symptoms of blown-ness?

After that i would check for metal shavings in the fins of the FETS. At different times some are HOT and others a Ground..... metal shavings from hot to ground = bad!!

This may sound stupid bit is worth mentioning. Don't blow compressed air into the victor fans.. It makes them go VERY fast and produce a voltage the the victors are not designed to withstand.


Fun little experiment:
Take one of those useless little muffin fans included in the kit and blow conpressed air through the blades. If you get the angle right, it will spin unbleievably fast and make an earsplitting noise. Don't do this to a fan you are using.
