Any electrical guru out there that can recommend using a multiplexer or splitter of some sort to rig a single PowerFc to drive 8 ignitions in 4 rotor application?

Info is appreciated... thanks...

What is the firing sequence, is it like twice a 2 rotor?

Firing sequence is 1-3-2-4. Thus rotor 1 & 3 acts like a single two rotor engine, so with rotor 2 & 4.

You could probably look at it as rotor 2 & 4 are 90 degress out of phase as compared to rotors 1 & 3.

Okay this seems pretty straight forward, since it is not firing like the 20B. This is just an idea, I have never tested in obviously.

Splice an additional leading coil in on the same wires as the current one, this gives you your 4 leading.

Replace the the T1 coil with a leading coil so there are two outputs firing simultaneously, this will give you trailing spark for two of the rotors on the same cycle (I guess 1 & 2). Do the same with the T2 coil for other two trailing plugs.

So total of 4 leading coils used. Shouldn't cause too much of an issue with the igniter.
