RE: magix extra or twist 3d?
I owned Magic Extra, and I flew my friend's Twist twice. Both are similar in price range, size, and flying. My friend's Twist was nose heavy for 3D (he got 6 oz of lead under engine) and not propped for 3D, yet it did very well. I think Twist is capable of being better than Magic Extra, if set up right. It has larger rudder, thicker wing, and easier to achieve a 3D-aft CG. I rember having to jam my battery pack into the tail w/ a customized hatch for my Magic Extra.
