Propeller and flaps

Next are the propeller and flaps - the model's in fact almost finished now.

The propeller blades consist of a metal core with paper tightly wrapped around it. To get a better grip of the propeller blade shaft to the inside core I extended the collar at the lower end by a few millimeters. The pin sticks inside the hub and the remaining visible white collar inserts into a collar glued onto the axle inside the hub. It's quite a strong construction. I enlarged part of the instruction drawings to get a 1:1 scale with the model and used that as template for proper alignment of the propeller blades.
The entire assembly runs very smoothly inside the brass tube fitted in the nose section and as you can see the engine run-up was successful .

Flaps down are almost at a 90 degrees angle (one position only). Not difficult to make but cutting out those small ribs was, how can I say, a bit of an unpleasant job. Note the small indicators on both wings - to provide clue to the pilot that the flaps were indeed down. Indicator lights on the instrument panel were not in fashion yet in those days as it seems.

Well, what's left? The antenna, position lights, final touchups, a bit of weathering/dirt to add and a coat of matt varnish.
