the motor has a max current of 25A. so you'll probably need an ESC at around the 30amp mark. the 20amp will not suffice.
your battery is going to be very heavy for the power setup. you'll have to cut down on the Mah ratings, somewhere around 1500mah should be the limit. but if you can make the plane VERY light, then that should not be a problem.
the radio is fantastic for the price! i have one of these, and its absolutely beautiful! (as long as you can carry a laptop everywhere just in case you forgot to reverse the servos!
