The coil would have a lot to do with current draw. The Modelectric coils are supposed to be low current draw and able to operate on NiCads. Granted "low current draw" is very vague. Does anyone here use the Modelectric coils? Any idea of current draw?

hi guys,
5bears.com has transistor ignition schematics that look the same as those at jerry- howell.com, just go to his radial engine section. beware though, these are current hungry kettering type ignitions, not CDI! i experimented awhile ago with an ignition module from an old suzuki swift distributor and although it was compact, light, and super reliable it took about 2.5amps at 6volts! would need a massive battery to get any decent run time. sure had fun though, even with all the shocks i got!
