I'm also wondering what is the reason for the wire from the undercarriage housing to the centre of the wheel.

Any suggestions.
As a matter of fact, a Polikarpov I-16 have been equipped with neither an hydraulic nor electric mechanism for the main landing gear opening and retracting. It was a machinery operated manually with these steel wires. There was a crank for retracting and opening on starboard in the cockpit. A pilot needed to make 44 full rotations of the crank to retract the landing gear.
A nice progress on the model Vic. Looking very good.
