Ordered the FPVLR antenna upgrade from drone nerds. Since they are about 120 miles away it only took a day. Installed it today and went out for a fly. Previous over my neighborhood I could get about 2100-2500 before I had to rth. First flight I hit 3200 and brought it home, second one hit 4k and decided to call it a day. I'm ordering boosters right now lol. Here are some pics installed.
