Choosing Esc and Battery

Hello All. I am making an arduino based rc airplane with 1 km range(I.e nrf24l01) I'll be using a 2200kv bldc motor.Which Esc would be the best and cheapest? I mean 30a or a lower one and which battery should I buy that would give me a good fly time( about an hour or half) as well as save my money.

A motor with Kv 2200 could be any size, its just a measure of back EMF v. angular velocity.
You give no clue to the type, size or mass or the airplane so there's little to go on.

Do you want the best ESC or the cheapest ESC? You cannot have both!

The nRF24L01 is not a great RF comms method, its 2.4GHz and high bandwidth and thus has
much smaller range than longer wavelengths / lower baudrates. Go for something in the VHF
band if possible, or even standard RC control kit - its cheap, it works and the range is known.

Thanks for the reply.I think that nrf has 1km range.and my airplane would be a small rc airplane with single motor and I am going to make it about 40-45cm long . Material will be foam and Motor is ((http://www.amazon.in/gp/aw/d/B01H0R7FIK/ref=mp_s_a_1_1?ie=UTF8&qid=1478446034&sr=8-1&pi=SY200_QL40&keywords=2200kv+brushless+motor&dpPl=1&dpID=41suPijDVNL&ref=plSrch))

Why would you think that? Its 2.4GHz with a small PCB antenna, 0dBm transmit power, -94dBm RX
sensitivity at 250kbaud.... 2.4GHz has to compete with lots of microwave ovens and WiFi in the area, so in
practice the range is barely 10m, or perhaps 50m with PA+LNA

Well that link recommends a specific ESC for that motor....

I didn't get that Where does it specify esc for the motor .Well can you tell how much amps Esc should I buy.And also how much voltage and mAh battery :o

didn't get any reply i asked what voltage and may battery should i use for approx 1hr flight time
