I have one that has loged over 100 flights and it flies perfectly, very good plane. The manual calls for the CG to be at 93mm behind the wing´s leading edge, however, I found it to be nose heavy with the CG at this location, so I moved the CG aft 6 mm and the plane now flares well for landing and is very gentle in flight. If you need the manual, you can download it from the manufactuirer´s web page at http://www.theworldmodels.com, it is in PDF format. Hope this helps, enjoy it.
