I admire your tall leap from the Magic to the Carden Edge. The magic is a very versatile design and can be set-up for many different styles of flying. Do you have a computer radio? Ring-it out, try elev/flap coupling, airbrakes, ail/rudder mixing and any other kind of mixing you can do. Just to understand what everything does and how it affects the airplanes flying characteristics. Is the Magic all you've ever flown? It falls into what I like to call the "powered kite" group. It can be misleading as to what your actually flying - the engine or the wing. Granted, you can do the same thing with an Edge but when a double tapered airfoil quits flying(snaps) on you, you'll be the 2nd to know....the ground will be the first.
The CF ldg. gear sounds like a good idea, I hear the stock one is not so good? By all means, move the CG around, just be cautious as you move it aft. An aft CG will make your Magic more aerobatic and make your wing more efficient but inherently less stable. Its great to see someone so young, so fired up about flying, especially this time of year, when schools in.
