ADS-B, Mooney, Upset Training
Your article on ADS-B transponders suggests you can save $500 by wiring in your existing Stratus portable ADS-B receiver to the new Stratus ESG transponder, instead of buying the new 2i receiver. This is true only if you don’t wire it in, but continue to use it standalone. I just had NexAir Avionics in Massachusetts install the Stratus ESGi transponder system in my Ercoupe and I chose the package with the 2i because the savings without it is only $350. That is because the interface cable set costs $150, but its included with the ESGi bundle.
