Thanks for your response. I've since figured out the problem. There are some long threads about this model. Apparently the instructions reference to the correct CG is off by as much as 15 mm. Almost all the contributors to the threads about this Model had to move the CG point a lot. For the manufacturer of the plane to be off by tbhis much is unacceptable. It is guaranteed that many crashed this plane on first flight because of tail-heavy instability! And you're right. It is damn hard to land !! You have to come in very hot!! Thanks again.
