I got the new ignition system as Steve from Cermark as promised. I have not had a chance to fly as the weather here has been nasty. But I ran it on the ground with the new ignition system and a new Champion RDJ8J plug. It run good on the ground with good transition and good idle. Idle is at about 1,700 rpm. Full power with an 18-6 prop is 6,350 rpm. I think this will do good for sports flying or scale. The prop is on the large end of the scale for this engine.
