I was a beginner 3 months ago and know completely nothing about a quads. Now I'm still are but know a lot more and fly few times with my own fpv build racer quad. After watching every yt video about this hobby I went for shopping. I don't want to spend milion dolars on this because I was not sure that I will have fun with that and also time for fly so that will be the cheapest build that I could make BUT! that are nor a crappy parts like I ordered first time.
First of all. You want it cheap It will not be! If you haven't about $300 don't even start. Believe me I tried to make it cheap and you can buy cheap parts but there are so many things that you need and don't ever realize you will for now. I'm not talking about the basic tools like glue gun, solder iron etc. there are a lot more, but for starters:
If you have some time and don't want to spend a lot of money buy in China. There are the cheapest components in the world. There are 3 main sites:
Aliexpress -
http://www.aliexpress.com/ (Chinese eBay)
BangGood -
http://www.banggood.com/ (Chinese online shop)
GearBest -
http://gearbest.com/ (Chinese online shop)
Search, compare and read the buyers reviews. Choose the best option for this components:
Frame - ZMR250, QAV210, QAV-R (doesn't really matter) whatever suits you the best or whatever is the cheapest.
Flight Controller - Naze32, SP Racing F303 (CC3D is old and don't give you that much possibilities like for example Naze32)
ESC - Racerstar RS30A V2 30A (New, good quality, cheap and if you don't brake them can be used with better motors, better lipos (4s) and better propellers in the future)
Motors - Racerstar Racing Edition 2205 BR2205 2300KV (Very good opinions and very cheap motors with a lot of power. Much better than Emax MT2204)
PDB - You can buy the simplest one they are cheap but probably you will buy another in the future with voltage regulators for more advanced builds
like this one FPV Camera - You can go with the cheapest one
800TVL for $10 or buy something that is easier to mount and change angle and will feet most of the frames
Like this one HD Camera - Mobius or Xiaomi Yi or any other action cam will work. Mobius has a good shape it is easy to mount this but maybe harder to angle. Thare are a lot angle ready plastic mounts for GoPro or similar that you can use on Xiaomi Yi
Googles - Are better than monitor on a tripod right? I suggest Quannum v2 Pro. Cheap, good quality, you can use any video reciver with them and power it with any lipo (3S)
Radio - FlySky FS-i6 good 6 channel radio for beginners with lots of possibilities for example 10 channels firmware mod in the future (buy only with Ia6B reciver)
Lipos - Cheaper but better for begginers 3S with at least 40C. Probably 1300-1500mah (bigger lipo will be to heavy)
Charger - Imax B6 or any other 4 button charger with balancer.
Video transmitter - TS5828 small, cheap 32 channels 600
Video reciver - RC832 cheap and works fine.
