Amen to flying. It's beautiful here. Yes, iFly GPS will work with the Lynx NGT9000, just select FreeFlight as the wireless device. We are adding Lynx to the Connected device list in our v9.4 update as well as Stratux. We'll be adding more as confirmed. My suggestion for other models, like Sandia, is to connect to it via wifi, then go through the list if Wireless Devices in the "Connected Devices", pause on each one for about 30 seconds. If you see heartbeats counting up, take it for a test flight.
