Purchased a ready made Stage 1 and I am a little disappointed. I bought into the 2 to 3 times the range of the stock P2 Vision + range from what i've seen my stock extender gets about the same range 640x480 15 fps. I am not trying to bash FPVLR at all I totally believe in the product. I just hit the wall at 3200 ft just like my stock extender. Maybe I need to upgrade my antennas on the quad?
