You will be happy with your purchase.The Dragonus is a very nimble and stable little bird.I've owned both a intruder and elite for about 6 months.
I can't think of any tricks for radio install unless your using hs65 servos.The only other thing is that when using a 160-180g lipo the elite tends to be a little nose heavy.This is not a problem for learning basic maneuvers it can be trimmed but later on you will want to boom mount the tail servo to get a better CG.
