WHat do we think of 3 different planes, adn their possibilities with 5 different engines? LOL.

I can tell you that if you want something that is durable, the FuntanaX is not what you want. It's a great plane, mine flies beautifully, very precise and will 3d well with the cg back, btu it is a 3d plabne, and is built very light, and light equals damage in crashes and even less than perfect landings. The Showtime isn't out yet, but it should be very similar, they are also built light for performance. I don't have direct experience with the Mojo, but I've never met a profile that wasn't pretty tough, so that'd probably be the way to go, plus, they are supposed to fly great.

On engines, any of the ones you list would work. For 3d, I prefer 4 strokes, they swing larger props at lower RPMs with better throttle response, which is what you want for 3d. Teh biggest thing to watch out for on a 3d plane is weight. Get the lightest components you can, and you will have better performance, and less damage when you dork it. Whatever you decide to go with, look around and see what others are recommending for engines and equipment, and always remember that lighter is better, small battery, mini servo for throttle, no excess wires etc etc etc.
