okay but really it wont change the looks or the flight performance alot. the cap 231 ex and 232 barrow the extra 300 wing and guess what other planes do? the staudacher 300d and the... you got it the edge. but the wings are almost the same in the 2 kits except on the edge it has a lil less dihedral. which will cause the plane to stall out at a lil faster. the edge also has a slightly higher wing loading because there is less wing
