I finally bit the bullet and purchased a P3S and have been more than amazed besides after a few flights the vidio became choppy.Bought the Arg Teck antenna and my eagle turned into a TURKEY. Really wish I would have would have known about this forum before buying this Mod! First kit had a bad connector so I sent it back 2nd kit seemed to be fine after inspecting connectors under high powered mag. When tests began I started straight up too 200' and received a weak signal but returned strong so I went up too 400' and still fine. Started to fly further and reception was still constantly coming and going (never had these problems w/ stock RC). At about 2500' I lost every thing and my nightmare began! I proceeded to different parts of my yard to get something but nothing. By then I didn't even have a line of sight on it(now starting to panic big time). It was not clear in my mind if RTH was actually engaged or not and if doing it manually would work having a black screen (still able to see a silhouette of the map though) so I started making my way to the truck to maybe chase it down (LOL) when my screen came back. 6 mins left of battery! I control forward and distance increases I control backwards and the distance increases(%^@!#$*). By the way I still don't have video but I can see the distance values. With 4 mins left I hear a buzzing and bye God the thing is behind me and full video comes back the only thing is she's goin down! I find her 20 mins later in (believe or not) almost perfect shape besides 1 scratched prop. The next day I without hesitation go back too stock but video is so choppy I can't even fly. What the Hell have I done? Its 3 wires for pete sake and they all snap in tightly! Any help would be so appreciated. I never should have messed w/ a good thing but just wanted to have better video quality. Forgot to mention that well before the mod the choppiness in the video was starting to get worse and worse but I thought maybe it had something to do w/ the memory in my phone getting low (not the case).
