Hey people!
i am Sunny kalyani from a small town...I love RC and it is true that one's it bites you, you can't leave it...
Long story short i have a S500 quad frame with a naza m lite and gps... flies nice but, you know its boring... because its big and a little underpowered, planning to put a 4s on it but its a future thought.
Right now i want to go into the FPV world... so i want to make a small fpv quad and i have decided for 3 options as follows:

1) JUMPER 260 RACING QUAD
http://rcmumbai.com/products/jumper-260-racing-quadcopter/
jumper 260 quad is a nice ARF quad deal from rcmumbai... i want it as it has practically everything i just need to toss in my turnigy 9x receiver and also it has the camera with gimbal and also a reciever for the camera...but you know i am not that of a multiwii guy which comes integrated with it...

2) WALKERA RUNNER 250
http://rcmumbai.com/products/walkera-runner-250-fpv-racer-rtf-without-remote/
Walkera runner is again a pretty cool deal...its again has everything but the big problem is that i dont know if i can use it with the stock receiver of turnigy 9x as it comes preloaded with a devo 7 receiver...and again it has a walkera FCB not sure about its perfomance...also the price point is a little bit more(just a little bit)... but i love it lot and if any of you guys can tell me if i can use it with my 9x i would actually buy it.

3)MAKE MY OWN QUAD
so the last option is to make a quad with my own choice of parts...i would love to use a qav250 with naze 32 but you know in this option i would have to spend a lot of money as i want to put FPV in it as that is the main reason i am building a 250size quad

please help me in choosing...thanks for reading

One more question...can i use a 4s battery on my setup ie. s500 with dji naza with afro 30 am simonk esc with multistar 920 kv motor

Thanks for reading and solving my doughts
Happy and Safe flying

bro last option is good i have my emax nighthawk pro or go for diy experiance
safe flying.

I believe that if you want really high performance, the only ARF option is an ImmersionRC Vortex and even then I think a DIY quad with the right choice of parts will still perform better. Depending on your budget and what level of performance you are looking for - top of the line or just fun flying, we can try suggesting parts.

I don't like the Jumper much. MultiWii is outdated and I don't understand why a racing quad needs any kind of gimbal. If you don't care as much about flight performance this might be a decent option but I am not sure if spare parts are available in case you break anything (which is bound to happen with racers).

I can suggest the following parts if you want to build your own quad that will perform well at a moderate price point:

FC: XRacer F303
ESCs: DYS XM20A/ FVT Little Bee (available at RCHyper)
Motors: RCX H2205 - 2350 or 2633kv (budget option. powerful but not as durable though spare parts are available), EMAX RS2205(the king right now), Cobra 2204 (available at RCHyper)
Frame: Trusty old ZMR250 or the ZMR250 V2

FPV Gear: HS1177, Aomway 200mW V2 and the Quanum DIY goggles with a RC832 or FR632 VRx
