I was just reading more about that Genesis system. They can provide it adjusted to put out 12 volts. One could hook that right up to a point triggered or Hall Effect triggered Kettering style ignition system and go fly. All you would need to come up with would be the ignition coil. One might need a 12 volt battery to power the ignition until the engine started and the charging system started putting out.
Now, one of you needs to buy the Genesis system, reverse engineer it, and figure out how to do it on the cheap!!
