Hi everybody, Steven, We purchased an arc200 few weeks ago and we're quite happy about it. We use it in an hydrofoil and it works great! We were using a wireless remote control then move to a wired remote control. We switched then from the throttle plug to the pwm plug. Yesterday we wanted to switch from the wired remote to the wireless and then we connected our receiver on the pwm plug and we configured the arc to use the pwm with encoder as we use to do. Our first receiver blew up and the second one we had didn't work. We mesured what we had at the output of the ubec and it was quite strange. No current between the black and red wire. And 5V between the white and black and 5V between the white and red! If we mesure just before the bec at the output of the arc we have 5v between the black and red! But we still don't know what's going on and why it was working before and not anymore. Any idea?? Matt
