"Good avionics shops are hard to find. Excellent ones are even more rare. In my estimation, Leading Edge Avionics, based out of the John Wayne Airport in Orange County, is the best facility in Southern California. We use them for all of our avionics needs, including routine and un-routine maintenance, ADS-B solutions, equipment installations, etc. Their team of technicians is excellent, with customer service to match. I recommend them to anyone is who is need of quality avionics, no matter how small or large the scope of work."


"Leading Edge Avionics went above and beyond with their customer service and punctual delivery of my airplane. Although it was a small job, further complications arose that were dealt with in a knowledgeable and timely fashion. They informed me every step of the way and made sure I knew all of my options. Thanks for the help!"

"Fantastic work. These are great people. They are first class and I wouldn't take my plane anyplace else. Thank You guys for a job that looks much better than I could have ever imagined. Well worth every single penny! I highly encourage anyone to use these people over all of the competition, which in my opinion, there is no competition or comparison."
