I updated my 59 Piper Comanche PA-24! I updated my 59 Piper Comanche PA-24 250 & will be ADS-B Compliant with a SkyBeacon. I opted to update the Nav/ Position lights with the matching Sky sensor while getting ADS-B In with GPS & WAAS. I also ordered a AV-30C Bundle with Circuit breakers & an OAT sensor to upgrade my instruments. I probably saved several hundred dollars with the LOWEST Prices, Coupons, Free Shipping & NO Tax!! Martin was super helpful thru the Chat Window & answered all my questions.

Got my AC-30Cs quickly and well packed… Got my AC-30Cs quickly and well packed avoiding damage. I had an issue with Fed Ex, and if I’d thought about it I would have requested UPS even at additional expense, but that’s not your issue. I’m really looking forward to getting these installed during my annual next month!

Quick & Accurate Service When I initially order these items it indicated it would take 7-10 days to ship. I was surprised when I received my shipment in about 5 days. Well packaged electronic items and quick service. Thank you, GSS

Great customer service Great customer service, antenna delivered quickly and at a great price.

All parts eventually arrived Parts showed up and were as described but the most expensive part of the shipment was several days late and required me prompting the business 3 times. Would’ve been 5 stars if I didn’t have to wonder what was going on with my order. In the end they ate the cost of next day shipping so kudos for that, just shouldn’t have been necessary.
