I use the **** out of them on my mojo 40 with a five cell. tail smashes (tail taps gone a little wrong, where you hit the tail too hard), very violent snaps on take off, basically I fly the plane like I hate it and the servos take it all. Ya they can take abuse. just watch the full throttle runs, because it will handle them for short 7 sec runs, they (or any servos) will give out and the surfaces will flutter causing you prized airplane to crash. (never happened to me but I have seen it happen). so if you use the up and down movement on the left stick and never go full foward unless in an upline, you will be fine and you will love the airplane.
