Bill,

Dick Hanson had similar things to say about his experiments with spark ignition on the ST2300 a number of years ago. I am a 2 stroke guy, so never had to worry about the YS handling issues but I had wondered if spark ignition would make them easier to deal with. Since many people are now building glow powered 2M airframes well under 11lb, the extra weight of the ignition is not a terrible penalty to pay considering the returns. Just the fuel economy increase is worth it alone, with the cost of fuel where it is now.
