The breaking out of the wood parts was a bit ticklish, and the assembly is not for very small hands (rubber mounting of the elevator). The molding has a few margins. - My son (5), however, is happy and proud of his flop: - Through the balsa everything seems much more noble than a plastic flier (= admiring glances in the park) - The rubber engine and propeller work well (and convince the little guy) - Our flop flying in a spiral (as empennage not well aligned) which gives a saving the run after.
And all in an adorable 70s package for the price of a plastic part. Caution: Do not lose rudder! (Which falls every time when landing from ..)
