In last few days I was working on bottom wing side...
First I glued few balsa plates in the middle...





Then I must made few jobs before adding other balsa plates.
In the front, on some ribs I must add balsa stripes, because some ribs was lower than leading edge.



For ailerons I will use 5 classic hinges with pin inside. For them I must glued balsa blocks...







This blocks connect upper and lower balsa planks...

On the wing tip, before start working on tips, I installed carbon tubes for wires for lights in wing tips.



Zero haven't landing light, so that is one job less on this model...

Every area between ribs, under upper planks, on flaps part was reinforced with one more 3 mm balsa plate.





I connect balsa spars again with 3 mm balsa. On that vertical balsa will come fir plate in which will be screwed flaps hinges.
For flaps I will use 1,5 mm thin G-10 plate. It is ideally flat and enough strong. Because Zero flap don't need gap between flaps and wing, installation will be easier than on P-47...

Yesterday I sand wing, and all edges. Wing is very rigid...
