Almost forgot. I also talked to ElectroAir yesterday about their progress on a replacement for the "D" magnetos. They have changed their approach, hope to have it ready by Oshkosh, but did not have a price. If I remember right, the cost of their current system to replace a single magneto on a two magneto engine was about $4000. So I'm guessing we are probably talking about $6000 or $7000 but we will see when it comes out.
Their new approach is to build their own standard magneto that will replace the "D" magneto. On the shaft of that magneto there will be an inductive pickup that will be used to trigger the other ignition system which will be electronic.
