Help with first time build

[Chester (newbie)]

Hello there,
I am in the process of choosing all the parts I need to build my first FPV Quadcopter!
I have decided that I am going to buy the REPTILE500-V3 frame.
For the control board, the Hobbyking KK2.1.5 Multi-rotor LCD Flight Control Board With 6050MPU And Atmel 644PA
I am stuck on which RC transmitter, motors, flight controller and battery and charger to buy.
If you do see any obvious mistakes I have made so far, please do tell me as I am new to this world!
My quadcopter needs to last a reasonable amount of time in the air (20 mins) and be able to travel a long distance.
kind regards

Hi mate and welcome , as on the motors dont go over 1000kv , a low kv motor with a big prop will give you better flight times about an 800 to 950kv and a min of a 10x4.7 prop
Battery 4000 to 5200mah 3/4 cell depends on motors
Transmitter there are not many long range transmitter futaba or spektrum are full range the turnigy xr9 pro has a long range module that goes in the back but never used one
Long range FPV needs a top set up 5.8g but antenna is really important on how to get range ,If your in the Europe you can only use 2.4w of power from the FPV tx ,if your in the USA I have a mate that is a member of the forum but he makes long range FPV quads he will build if you want or just send you a kit and you can build
Here is his site take a look and here is one of his videos
