I got no new video for you guys, but some interesting results.
A flying buddy has the ImmersionRC 600mW 5.8GHz Tx on his flying wing and the DUO5800 v2 (Airwave Chip) receiver with a SPW and a 4turn helical antenna.
He tried to reach a specific location but never got further than 3.2km. Soon after passing the 3km mark, his video gets very distorted and he even got some total signal loss.
After his second try i gave him my UNO5800 v2 (Nexwave) and he connected his 4turn helical to it. Than he easily reached 8km without any drop outs!
So guys, get rid of the airwave based receivers and get a SkyRf or Nexwave System 🙂
