Re: New Talon Speed Controller

Thanks for all the fine testing and analysis, folks. I snagged half a dozen Talons through First Choice today. I hope they provide joy. I intend to use them for CIMs, with fan. You'd be crazy to not use a fan if you can use one, as the lifetime of electronics is exponentially increased by cooling it a few degrees.

Having designed a smaller motor controller for underwater stuff, I have long been mystified at the behavior of the Victor 884. I'm under the impression (from reading the CD archives) that it doesn't short the motor winding in the off phase of the PWM cycle. Is this the case, or does it do something else to make it so nonlinear?
