My only complaint about this kit is that the balsa wasn't cut all the way through the sheet. This was easily remedied by block sanding the back side of the balsa sheets with very fine grit sandpaper. Parts easily popped free once that was done.
Built mine with adjustable rudder and elevator surfaces. Liked this plane so much a second kit was purchased for a future rc 3 channel project.
Ample amounts of grey tissue are included which is a good thing as my tissue skills are poor.
