    On the same range I hit 2km last weekend, I decided to push out even further on the stock remote control and receiver. FPV provided by IRC 5.8Ghz 600mw vTx with a Fatshark Spironet antenna and Fatshark Attitude V2 goggles with the TrueRC Crosshair antenna. Great video out to 2500m then intermittent static to full static out to 3.4km. Failsafe/Return to home kicked on and off at 3.3-3.4km. Here is a youtube video of the run.

    Wishing for more range and smooth panning control, I upgraded to a Futaba 14SGH & R7008SB receiver yesterday with the first three runs pathetically short of the stock tx/rx range averaging 900m before hitting FS. I will test different rx antenna placement to see if I can improve the range. Not convinced the required 90° positioning is ideal as suggested by Futaba.

    While the 14SG range pales in comparison, the functionality and control of the quad while filming is incredible. Smooth pans and tilts on the gimbal.

    Thats not very good from the Futaba in fact i doubt you will get much more out of it even by re arranging the antenas .I always thought they were superior to the standard Dji transmitter but i guess not .

    Posted in a couple other forums...

    2200m with 14SG & stock Phantom 2 Rx.

    I reinstalled the P2 stock rx and reconnected to the Naza controller today while leaving the Futaba R7008SB rx that came with the 14SG inside the shell but disconnected.

    Out on the same range with the stock rx and the Futaba14SG, I easily reached 2200m and felt I could go further. However, with the temp at 14°F, the battery was dropping voltage fast. Winds were calm and my altitude was about 120m above relative position of the home point (5300') with 95% humidity. This range is wide open country with very few trees and away from RF activity. This is the same range and similar conditions in which I reached 3400m with all stock P2 gear (FPV gear excluded) yet only 940m with Futaba gear on both ends (14SGTx/R7008SB Rx).

    I am encouraged by the results knowing that the 14SG is providing powerful enough signal to allow 2200m distance. On a warmer day with calm winds, I may try to push out to 3000m with 14SG bound to the stock rx.

    Once the 400mm Futaba antenna shows up, I'll install on the R7008SB rx and post results.

    PS. It took me a while to figure out how to bind the 14SG with the stock rx. I found on another forum that the only way I could bind the stock rx to go into the 14SG Linkage/System and changing mode to Fasst-Multi mode. With the 14SG on in transmit mode, push the bind button on the bottom of the P2 until the solid red light emitted from the button starts to flash. Once its bound, the light emitted from the bind button turns green on the P2.

    An update....

    I upgraded the R7008SB futaba receiver to the 400mm boat antennas and hit 2800m today with the 14SG. While not the 3400m I have reached with the stock rx/tx, it is much better than the range with the antennas that came with the R7008SB limited to <1000m.
