Hey all! I'm new to the forum but been a Flite Test fan since the early days. I've been building quads for about 4 years now and have run into a problem I've never had before. I just switched my miniquad from CC3D to Kiss and I can't get my ESC's to recognize the FC. All they do is beep slowly like when they've been disconnected from a receiver. I'm running Simon K ESCs. I have done throttle calibration one at a time through the receiver and they work fine but once soldered to the Kiss board they're back to that slow beep. The FC shows all the perfect signals and even arms. If anyone has run across this same issue and knows how to resolve it I would love to know. Thanks, dronlvr
