OK so I've had my Phantom 3 Standard for about a month now and it's my first venture into the world of remote control aircraft. I'm loving it, but I'm in the UK and so restricted to the CE mode which kind of limits the distance the Phantom can fly, and so I'm wanting to modify the setup so that I can fly beyond the 400-500m range that I'm getting now. I see there's a fair few ready-made mods on the market such as the ARGtek, Itelite DBS and the FPVLR long range kit that looks like something out of a 1950's sci-fi movie. I've been reading reviews of these devices, and looking at the FPVLR kit made me think it really shouldn't be too difficult to build your own mod that could maybe equal or surpass those ready-made mods that are on the market. The thing is though that I don't have the faintest idea about the principles involved and everywhere I've looked to try and delve into the topic people are talking in jargon and it's melting my head trying to figure out what they're on about. I'd really like to be able to build something along the lines of the FPVLR kit but right now I'm about a million miles from that goal. Does anybody know if there's a good beginners introduction anywhere online to the principles of radio transmission and reception for model aircraft? Thanks.
