I recently used Accurate Aero for an ADS-B upgrade in an aircraft I recently purchased (Piper Tomahawk). The entire project consisted of a new transponder, new radio, new ADS-B in hardware, in-panel USB power plugs, various and necessary certifications, and a whole lot of house cleaning behind the panel. I have to say I was impressed from start to finish. During the initial phases I was presented with several estimates with a variety of hardware and had all questions answered thoroughly about the pros and cons of each. I eventually made my selection and work started quickly. During the project I was most impressed with the high level of communication I received. When the project was completed at the time promised, there were no surprises with respect to billing. In other words, the original estimate was followed. It's important to note that while getting estimates for this project I must have spent about four weeks contacting avionics shops far and wide. I probably reached out to six or more. Accurate Aero was the only facility that actually followed up thoroughly with me. Overall, I'm very impressed and recommend these folks 100%. read more
