Thanks again for the input.

I can see advantages to electronic ignition for a twin,... synchronizing the engines would be a snap by comparison and I've heard there is an available "fail safe" for such systems that kills the remaining engine should one drop out.

I'm unsure about the weight issue. What I mean is,...

A p-38 has a lot of weight behind 1/4 mac. I was thinking a magneto ignition would place more of the "usable" weight forward of that point. The extra batteries required to support electronic gear may not be substantial, I don't know. I do know they would have to be forward of 1/4 mac, which is where all other batteries will need to be. I like long flight times, 30, sometimes 40 minutes rather than multiple short trips.

My preference would be to do things old school and being inventive rather than increasing the budget (which is limited) to overcome issues.
Having the timing resolved leaves two (hopefully) issues of concern

Having an auto kill switch for the second motor should one fail,.. ( I have some Ideas )
And what seems the most difficult to me,... how to synchronize engines.

If these are beyond my ability, or if the cash outlay starts to look like 60-70 % of cdi and engine management, easier is definitely better.

So,...What do you know about kill switch systems and synchronization?
