HELLO guys. This info might help anyone wondering about distance for the INSPIRE 1 V2.O. stock antenna. I still had full signal video and RC when i turned around. Very interesting with the amount of battery power to reach the 16969ft (3.2miles) 26%. Then with the light headwind coming back AND I mean hardly any wind took up 48% of the battery. We need to keep that in mind, even a slight wind makes a big difference. Landed with 26% battery left. For a round trip of 33603ft (6.36 MILES) I AM IMPRESSED BATTERY : TB48 100% charge WIND: very light, not enough to hold a flag up.
