Thanks for the reply I received my 12 dbi mini black hawk fpv package from horizon for the black pearl black mamba kit! Got the nimrod and clover leave set and is crystal clear out to 1.5 km before rth kicks in from loosing my signal on the 2.4 radio side! Horizon mentioned if I bought the 2.4 ghz LHCP 9 dbi black hawk for the pilot side only they believe I could get 2 km alone without doing bird side. Gonna try it and if I loose gain I'll add to the Bird ! but you mentioned the data link which I just had delivered and if I understand correctly you mentioned once it's programmed on the ground it will fly to receiver limits only?? I am using the PC ground station now so if it looses the link from there does it continue its mission. Also do you think it's to much weight to have the H33D gopro, IOSD, Black Mamba , horizon Nimrod , and the 2.4 data link on the Bird to fly. Of course I know I've already lost 10 minutes of flight time !!
