Personally I use the Foxeer HS1177 (RUNCAM SWIFT CCD 600TVL) it has a decent case and a CCD sensor however CMOS seems to be winning the CCD/CMOS sensor battle as it uses less power and has higher rate image/data transfer and in FPV the latency time is important
So your camera choice is looking good.
You can use any AV transmitter you want, I like the FT952 and have used it at both 25mW and 200mW with good results. Just lately though I'm moving over to the FXT X50 which is much easier to mount (bolt down alum case) with vertical antenna socket.
The Aomway antennas are well respected but I'm told the Skyzone are exactly the same but cheaper. For starters though you can't go wrong with a cheap set of circular polarised high efficiency set (only £9.99 the pair)
I don't represent Unmanned Tech but these above mentioned parts are available from their webshop at great pricing.
Your text says you intend using the Easycap with your Android phone but as it has a normal type A USB plug do you meant a tablet? or am I missing something again
I have no experience of the AV recorders, I prefer to fit a HD camera on the quad which records to a uSD card, this gives the advantage of both video and still shots (the Legend One can be controlled from your TX) If the cost or risk of a GoPro Hero is a bit daunting try another cheaper action camera e.g. Foxeer Legend One or Mobius
The cheap Chinese GoPro clones are just not up to the quality.
Good luck with what ever you go with
