I'm having trouble communicating with my ESChttp://www.graysonhobby.com/catalog/graysonhobby-welgard-20amp-brushless-speed-controller-p-241.htmlfor some reason it will only work with the receiver and not through my micro controller(Propeller). I'm using the same PWM as the servo's and they work fine. I'm thinking that the receiver sends some kind of code to activate the ESC? I don't know but if anyone has a solution please let me know.Thanks,Sean Stone

No your microcontroller is fine, I've used the Propeller with ESC's and it works great. The problem is probably that the ESC isn't getting its neutral value when it turns on, a lot of those need that for their self-calibration. The thing is, ESC's can vary slightly in what their actual neutral position is. What I would try doing is, in your spin code, when you start the program have it sweep a small range around your neutral, the ESC will probably have some kind of indicator when it is running correctly. When you can narrow the sweep down to a small value, just have that be your neutral instead and you should be fine.
