high aspect ratio wing, horizontal stab and vertical fin.
carbon reinforced main wing leading edge and wing tips.
all four servos factory-installed in the wing.
very sleek fuse.
stable yet responsive, easy to cruise, easy to thermal.

tips:

The factory recommended C.G. is 64mm from LE and it would be better to set your C.G. slightly aft. Now I fly with C.G. at 68mm.
Try aileron reverse differential. It will make flat and tight turn easier.

overall rating:

AAAAA: five of five, excellent.
