Bernhard Schrock Thx mates for you extraordinary feedback.
Gordon: I found a hint on an website that the H-1 provided a special seat (adjustable in heigh) because the very streamlined canopy. The pilot could raise the seat upwards for better sight during start and landing. But I could not find out how exactly the (divided in left and right half) canopy was stowed in the fuselage. Because of that I left it outside the fuselage.
