I have read a lot about using WiFi from behind glass so I tried it. Works fine on one of the flights I took the XSP out to 2000 feet. When I can get out to the spot I usually fly in i am going to see if it will go a mile. When it is this cold put the battery's by the heater vent or you will spend a of time hovering trying to warm up the battery. Heater on high,radio on, cup of coffee in the holder comfortable seat just like being up town.
