Surefly Electronic Ignition

These fellows have a certified simple magneto replacement that provides simple electronic ignition to your engines.  https://www.surefly.aero/

I am definitely keeping an eye on this - replacing the impulse coupled magneto would get you the easy starts.  And given that you can configure it to advance of the manifold pressure gauge you also get the better fuel economy at higher altitude.

I doubt I'll replace or rebuild a magneto again, I'll just move to this, I think.  Need to keep an eye on the news and see if they stay around for a while and if there are any issues.
