WM makes good stuff ... I love the Super Chipmunk, its a great plane for you to move on to after your 4* if you want aerobatic planes. If not you got your 3D stuff ... there are tons of it. Look at a few others like:

Fliton Extra 330 (its a big 40 sized plane that flies extremely well)
H9 Funtana (lovely especially the 90 sized one)
H9 Aresti (nice low wing pattern plane)
GP Shoestring Racer (I love this plane, if only it were cheaper here)

For me personally I will stay clear of GP planes (I am gonna get flamed for this), the quality is not that great compared with planes from H9 and worse of all in my part of the world it costs almost double of what you guys get in the US. H9 is about the same for us here.

More importantly, what sort of flying do you want? Scale warbirds, pattern, 3D, aerobatic or artistic aerobatics ...
