Greetings everyone! My name is Pablo and I live in Argentina. I finally got my fist Phantom last month! I previously owned a toy quadcopter which altough it had a nice camera, on my fist trip to the mountain, a strong wind pushed him out of the reach of the RC and went straigh down a river! With the phantom, is like enetring a new leage! Videos are amazing! Enough presentation, lets get to the low range problems. I bought the P3S on jan 2015 and after unboxing I updated software to v18.104.22.168 I noticeed at the very begining that the range was not OK. I´ve started to see erratic signal reception when I hit it 40 to 70 mts (either vertical or horizontal). Even using a printed windsuf antenna, the numbers where really bad. With the drone static in the air, on one moment I had full signal, and on other I got low RC signal warning, untill finally RTH was activated. (keep in mind thant since I´m in Argentina, my RC is set to CE most probably. At first I though it might be the wifi routers, the many trees arround, etc. But I tried some days later my drone on the farm and on the beach, with the same result. So, after reading & researching, relinking the RC, reading some more, calibrating RC, reading some more, calibrating the ICM and reading some more, I finally decided to open the RC. I´ts difficult to explain the releaf sensation when i slightly pressed the 5.8 pigtail connectod, and felt that unique sensation of the connector snapping in. After that and some hot glue later, Chorizo was tested (chorizo is like a "saugage" vey traditional during bbq´s, and its my P3S name). Got to 150 mts horizontal and 101 vertical with good signal, and altough i did had few signal lost, the RTH never got to kick in as the signal was recovered (keep in mind, a lot of tree, wifi, Mhz data links, etc. near-by). Conclusion, another P3S with the antenna connector unpluged, for the count! Regards! P.
