Tim,
I had a DA 50 ignition go out on me when I just test fired it in a stand. It couldn't have had more then a few minutes on it. Several of the guys at the flying field have also had ignition problems. One of the guys had it go out before he had the first flight on the plane. DA replaced without any problem. The same guy I just mentioned told me he called CH Ignitions and got a back up ignition from them. If mine goes out again I will replace it with something else..... Bill
