we can sum it up easy, allthough it will not be the most relaible coming out from me.

the ARF includes some nice stuff, wheel covers(removable), the awesome winglets you mentioned earlier,
a set of extensions(all in correct lengths to suite the airplane), steering tail wheel and over all high quality hardware.
The construction is very well designed and bring light frame with enough stregth to hold everything.
well done and packaged ARF..

Regards the flight, it can do any 3D in the book, and a great trainer for IMAC pilots,
it sure does all that like a "big boy" which like mentioned above, in a daily basis flyer..

More than that it useless if I'll say, so lets wait for some other guys who actually own the airplane
to post their thoughts BASED on seeing building, and flying it.

In regard to the main post of Cameron724, there are offcurse some other nice airplanes
that can do well, depend what you are after.
TMPro also have the Katana V2-46 which is very popular and turned to be great profile for everyone.
