Nice detail on the u/carriage. But I can't work out how the mechanism works to fully retract the main strut. (Last two images). Obviously, the main strut rotates about its end, (the end in the wing). For that to happen, the hydraulic cylinder must pull the end of the cylinder to main strut link, at the piston end, away from the main strut. But the piston has a very short stroke, only enough to rotate the main strut by a few degrees, unless in some way the cylinder is forced to rotate about its other (non-link) end, down and away from the wing and round to a position parallel to the wing, pointing in the opposite direction and in the wheel bay.
Also, there is no supporting strut connected to the main strut and lying backwards to resist the backwards component of landing forces, especially since the main strut is at a great angle to the vertical and looks as though it would collapse easily.
(The plane obviously worked, and this is a model, but as a mechanical engineer, this sort of thing tends to bug me!)
