I had an Garmin ADS-B transponder installed here by Ryan the Avionics Tech. I am extremely fussy about work done on my older Bonanza because a lot of the scratches and tears in my beautiful leather interior was done by shops working on my plane. I can't tell you how pleased I am with Ryan's work. Not only did everything turn out as I requested (the first time), when I got the airplane back in the timeframe & estimate quoted, the install was perfect. No scratches, no aluminum filings or rivets on the carpet etc. that I usually get when work is done. Everything was perfectly clean, in its place, and he even managed to cover up some torn upolstery on the baggage compartment access panel caused by previous mechanics. The airplane actually came back looking better than when it went in. Ryan's Avionics install is a real class act and that comes from an owner who is an A&P and IA. I DO KNOW THE DIFFERENCE. I highly recommend Ryan and Ruby valley for all you Avionics and A&P needs. Their fuel and shop rates are excellent. read more
