I own a Supersport with about 50 flights on it & still on the original plug. I have not changed any parameters on the ECU, just fly it as it came out of the box.

I have had a couple of failed starts but they were probably due to operator error. The only dead stick I've had was when the starter came loose & jammed the engine on the second flight. This was fixed quickly & at no charge, it has run perfectly since. - John.
