I have a Super Cyclone replica engine in my closet.
It has a small coil and it runs on 3V. its quite light for an ignition system. The only drawback is it requires points on the engine.
In my misspent youth I used this system. It was the only system we had. It was quite reliable.
I just wonder why a modern system could not be made using this system. You could use just one 1100mah A123 battery for it.
I have a couple three old vintage spark ignition engines that are missing timer units. I plan on putting a CDI system on them to run them again. it wouldn't weigh any more than the old points, condensor, coil and battery pack would. They might even run better as it would generate a much nicer spark too.

Points and condenser weigh very little-about the same as the hall effect sensor. The battery required is 1/2 required for CDI. The coil is about 1/4 the CDI units I have.(RCXEL)
