My 160 is sitting on the bench due to the fact that I converted all of my planes over to gas. It's cleaner, cheaper and, IMO, more reliable. With the price of the new engines coming out they aren't much different then the big glo engines. If you really want to over-power this thing for all out 3D go with the 50cc but the 160 will 3D it as you saw in the videos. BTW that was about the 4th flight on my plane and engine in the video with Kyle flying it so it wasn't really even broken in yet. That's why he kept it high. Didn't want the engine to hiccup with the rudder 6" off of the ground.
