I need some help from you guys. I have an Evololution 58 that is new about 4 flights ago. The plane cut off in mid flight well after we got it down. I noticed that I had not cut out the cowl large enough for the spark plug wire and the fiberglass rubbed a small cut in the side of the wire (just insulation). I also noticed that the spark plug was loose. I took it home and fixed the wire with a small amount of silicone and tape. Flew the plane once today and short flight did fine but the motor cut off in midlevel flight at half throttle three times in a row. Battery fine, switch fine and repair to the wire looked ok. Could the hole in the wire be causing this or do I need to check something else? It's like the motor quits just like you turn off a switch which is not happening. Any suggestions would help. Thanks, Danny C
