I'm building an rv-7a.

Any new engine from lycoming requires a 50% deposit and a 120 day wait.

I wanted FADEC but backed away. I'm buying my new engine and
performance mods through Lycon in Visalia,CA and they push LASAR. I was
looking for a magneto option.

I've heard good things about GAMI. Haven't researched Lightspeed, other
than having a pair on ANR headsets.

Thanks for the info.
