I am in the UK and have a very good FPV booster set up if anyone is interested. It is a Hawing Booster with 1 directional panel antenna and 1 12dbi omni antenna, it is seated on a platform on a good 4ft tripod and is powered by a 3 s lipo which sits neatly next to it. I have had the stock fc40 out to 832mtrs with it. I was going to replace the directional antenna with a 2.4ghz FPVLR antenna which would have got it much further but i bought a P3 in the end so never got round to doing it. If anyone is intrested in the set up just PM me for more details. cheers
