Do you have any 12 volt to 220 volt power inverters
 about 400 watts?

 Heres one for 41.00 and 400 watts

 Good work Wade. I just ordered one.
 I can put my 110 volt unit back together while it still works :)

 I don't know why I did not think of this years
 ago. You can have two in the aircraft. If one quits
 you can plug in the other.

Excellent - now thats redundancy.
Will you be setting this up in parallel or bank switched like in battery
selectors?

Wade Bush

Yes a battery selector type switch  is possible. The inverter itself
is totally unmodified so any brand will work. In fact this ignition
system would work if you plugged it into a wall outlet :)

The capacitor switching circuits will be modular. One PC board per rotor.
This to accommodate three or four rotor engines.

So, this is the unit we should buy (for sure)for the for the upcoming Lamar
MSD?

If I were you I would not do it yet :)

This is not called experimental aircraft for nothing :)

I am going to find a way to test it on a good dyno for fuel
burn.

If it does not lower the fuel burn there are simpler
ignitions systems out there.
