I have a blue mountain avionics efis...

I’m sorry! Couldn’t resist.

I think the blue mountain avionics efis g3 is for experimental aircraft only

 

[Jesse Saint]

WAS for experimental aircraft only, not IS. They have been out of business for a long time.

Best tool to adjust a Blue Mountain EFIS is a hammer.

I can lend you a Microair transponder if you want to beat on it with that and not risk damaging a perfectly good hammer.

Nauga,
