I had the Electroair installed in my Tiger 14 mos ago by Roscoe. The computer that uses the manifold sensor to advance the spark is a definite plus at higher altitudes. I also aggressively lean my engine and the spark advance algorithm loves it.
I’m a little different than most plane owners in that my budget far exceeds my aircraft costs. So I don’t give much thought to spark plug cost. I actually have a complete back up set for the old and new mags. So I clean and gap them between oil changes. When I do my oil change the gapped and clean set goes in and I’m back in the air in no time. Cleaning and gapping is saved for a rainy day.
The new switch plate Roscoe made for modifying the starting panel goes in real easy, and makes the start panel look cool. Guarded toggles and no key to keep track of. If your worried about theft, asked Roscoe how easy it is to bypass your key switch.
All in all I have been happy with my choice.
