arduino pro mini with NRF24L01+PA+LNA to control pan tilt system on drone

Hi all,
I am trying to use 2 Arduino pro mini's with 2 NRF24L01+PA+LNA's to control a pan/tilt system on a drone, I'm not 100% sure on how to program my Arduino's to do this however and was wondering if anyone had any tips, I need the Arduino to take two button inputs per axis since the joy sticks on my controller are already being used.
Thanks in advance
Gabe

p.s. I'm not sure if it helps but here is the NRF24 I'm using (http://www.ebay.co.uk/itm/221667071147?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT)
