Let me understand.. you wa= nt to trade a solid state dang near bullet proof ignition system for someth= ing that has less energy and requires regular overhaul and servicing?

Unless you are installing in a high wing, gravity fed will be a non-sta= rter (even as a back up).

You would be better served with a dual bat= tery redundant electrical system. Some folks are even running permanent mag= net generators. If you lose an alternator/charging source, you can shed dan= g near all your load, and have over an hour flying time to get on the groun= d..

Chris's plane has dual battery, independent busses, and dual altern= ators. That setup is less failure prone than a mechanical device that WILL = require overhaul or replacement every 500 hours or so.

To answer you= r question, I dont know of ANYONE running mags on any auto conversion engin= es at all. Just lawnmowers and lycomings/continentals/franklins.
