The Disney XL is a slightly enlarged
version of the normal Disney. The 'XL' is 4% larger!
This will add some weight to the complete model, but it also adds a lot of wing and fuselage area, the XL has got 16% more area. Using the same equipment as on the 100% Disney will give you a model that flies even slower and more gracious.
Only 4% bigger, but it makes a huge difference, the XL is a big plane
Very small changes have been made compared to the original Disney, wingtip and cockpit are little bit less fragile. Fuse area is slightly larger and a bit more area is behind the CG to improve knife-edge even further.
