fpv receiver, for Android phone ?

Hello
My first build just trying to get my head round how everything fits together, could someone please recommend me an fpv transmitter, and reciever I'd like to view it on Android phone.

I plan to use a racestar f4s controller

Thank you
 
The android phone as a display part is a bit strange but looks like there is a OTG (On The Go) device that should work here: https://www.amazon.com/d/Rc-Vehicle-Parts/EACHINE-Receiver-Channel-Android-Smartphone/B071VZYLYH <--- reviews look pretty hit or miss so not sure I'd get this one but can look in related items or yah search for "OTG USB VTX" those are you acronyms :)

Also can look below for some options for VTX and see what has good reviews (racedayquads.com is another one with typically good quality parts)
 
It may be good but just minor warning eachine is in general sort of knock off or cheaper components that said this might be fine for $10 probably worth a shot.
 
Sorry couldn't really tell you what is best since my experience with different VTXs is pretty limited as well would try some YouTube research if you want to see some comparisons personally have used a few of the ones from AKK bought on Amazon based on price and reviews too though. Have noticed can be a big difference in how good various receivers work though so would put more emphasis on that side.
 
I've currently got about 6 eachine vtx's in use and they are all working fine, however I've heard that their mW rating is exaggerated, i.e. what they say is 800mW is actually about 200 mW so if you want a real 800mW you might want to choose something better.
 
Yah just because something is cheap or a knock off doesn't automatically make it bad, just had some eachine box goggles originally and the video receiver in them was pretty bad. That said just one bad experience and a buddy of mine had different pair of their box goggles and video receiver was a bit better so yah just a bit more of a gamble if a lot of reviewers are saying it's good then it's probably fine just beware of fake reviews used to bump ratings I always check out the 5 star (see if they look legit) and 1 star reviews to try and see what major issues people have and if they are self inflicted or really mfg or seller at fault.
