Paul,

For rotary, any opinion on which is better capacitive ignition or
inductive ignition electronics?

John Fair

The consensus in the rotary racing industry is MSD.
Capacitor discharge Multi Spark, One of my next projects
is to design and build a simple system to trigger off the shelf
dual or quad MSD ignition units. My hangar neighbor has done tons of
R&D on lean burn engines and he claims the more powerful
the ignition the leaner you can run the engine and the lower the fuel burn
up to a point.
