Hey everyone, Just popping in to tell my story on my DJI Phantom 2 w/zenmuse/ gopro Had lots of fun so far, learned alot. Now regarding the Vision system and TX and RX (transmit and receive) First,: I have a Gaui GV-100 vision system. And I would like to report that it works fine, so far. Here is the lowdown; -The stock little stick antennas totally suck, no range -I upgraded to DJI mushroom antenna set , the 55 dollar set. -Now it works 4 times better 1/8 of a mile range. -I also have a cheap flat panel antenna for the RX, that makes the range about a 1/4 mile -My Guai TX is 5.8GHz - 500mw power. So I wanted to get more range, so I decided to upgrade to the Immersion RC 600mw TX. -Well, it has no better range, in fact it seems like it is shorter range. -A total waste of time. - I am not impressed with the 5.8GHz/600mw Immersion RC TX, at all, well it is smaller and lighter, but that is the only plus. So, can anyone help me find a better TX in the 5.8 range the won't be too huge, I don't want the massive Boscam 2200mw system. It looks to heavy and probably uses a lot of juice. anyone know of something in the range of 1000mw? Thanks friends.
