Robert, I was flying today and the motor started cutting out. I landed and saw the Led light for the ignition cut off flickering as I reved the engine. I disconnected the cut off and the problem stopped. All of my connections were good. There are no visible problems. The Optic kill is mounted on the engine box with velcro. Do you have any ideas as to what the problem may be? Is there a history of the ignition cut off failing ? It has only been flown about 5 times. Is it possible there is a problem in the PE board?

Thanks
