I ordered a DJI Phantom 3 Standard Range Booster ITE-DBS01.4 from MaxxUAV.com and just wanted to say if you need anything for your drone they are very quick to respond! I sent a question on Facebook and they answered with 2 or 3 minutes! I bought a second controller from PWdrone and was going to put the mod on it but today when I tested it I got the farthest out I ever have (4700 feet) and could have went farther but my heart was beating so hard then I about puked lol. In the pic it says signal lost but that was because I put the controller down to take a screen shot, as soon as I lifted it back up I had signal. I plan on doing some videos of the range before and after.
