Hello everyone!

Im planning to build a long range fpv quadcopter with a GPS system and I need your advice! I want the drone to be capable of flying for approx 15 minutes with approx range of 4km (Maximum speeds of 60mph would be nice). I want the drone to be able to perform, Return to Home, Hold Position, Hold Attitude and of course Acro Mode.
Im still debating as to what FC should I use, Im currently torn between Naza V2, Pixahawk, or F7 Board + M8N with INAV. Any advice regarding the FC's would be greatly appreciated as Im extremely puzzled... I want the drone to be precise and perform its functions, and at the same time I dont want to overkill the build.
This is the sample setup I have created.
FC: Naza V2? Pixahawk? F7 + M8N?
Frame: Lumenier QAV-R2
Motors: iFlight XING 2207 1700KV
ESC: Aikon AK32 35A 4in1 ESC
Battery: Turnigy Nano-Tech 4000mAh 4S 30C Lipo Pack

FPV:
FURIOUSFPV TRUE D 2.4GHZ DIVERSITY MODULE
Furious FPV Stealth Long Range 2.4GHz VTX

RC::FrSky R9 868MHz 16CH Long Range Receiver & R9M Module System (EU LBT)

Radio: I already own Taranis X9 Lite.
