You list looks OK. I recommend that you get a spare motor, ESC and many extra props. Your AUW with the FPV gear will be getting over 1kg, so be careful with your prop choice. I recommend APC1047s because they never break in flight as the EPPs will do on heavier multicopters. Consider a higher c-rated lipo like the Nano brand in the 4400-5K mah range down the road too if you are planning to use this mainly for AVP.
BTW The FF FCB is $37 incl ship here: http://www.sunsky-online.com/view/24...f.y1kX212gb83w
Good luck with your build and fly safe!
