evo 1 and i never lost a bar on GPS are Video transmission. Very happy with the EVO 1. Turned around because of battery percentage. when RTH i had 39% battery and 8 minute flight time left.
just yesterday i did 2.2 miles but with a phone and not the tablet. check out my youtube channel. videos are on there. Stacey Reece autel evo drone footage Anderson SC
