Provides full featured integration with I Fly GPS. AHRS, weather, traffic. Nothing more needed. The 3i is the internal version which means it is designed for a semi-permanent installation in the aircraft. It does not contain a battery and it connects to the external antennas used for the Appareo transponder. Theoretically, it will have greater range than the regular portable Stratus 3 when relying solely on its internal antennas.

Works very well with an iPad running Foreflight. I can see traffic around me, metars, etc.

Q: I have a Stratus ESG already installed in my 1969 Cherokee 140. Does this kit have everything that I will need to have ADSB in, and to hardwire it to my transponder?

Yes, this comes with all components needed to connect to ESG transponder.

Q: Will this 3i slide right into the connection where a 2i currently sits? I just installed the ESGi with the 2i and the 2i has three red lights indicating that its fried. So, Im ready to go with the 3i if there are no special installation requirements over the 2i. If the 3i slides right in, is it possible to get JUST a 3i without the install kit? Thanks!
