Even though im still learning the pattern and havent flown my twister would building and flying a legacy be to much plane for me?
It won't be too much plane. But it'll be more involved to build, harder to adjust, more fragile in a crash, and harder to rebuild after.
The Twister wing construction will tend to burst the covering and pop ribs in a crash, rather than pulverizing. The fuselage will be less likely to break than a full fuse model, and easier to stick back together in decent alignment when it does. All the controls hang out in the breeze where it's easy see that everything is right and easy to correct when it's not, and easy to tweak if you think tweaking needs to be done.
Frankly, unless you have a really good friend who flies Advanced or Expert and is willing to trim your plane for you, then you should seriously consider keeping the Twister in reserve until you've learned the pattern, and flying a good flapless ship, like a Skyray or a Flight Streak.
