Hallo everybody...
here are some progresses:
Rudder

control horns made from 0.5 mm thin plasticard, the PE parts were not drilled and my attempt to make a hole through them resulted in spoiling the piece...
So I made them from scratch.

Here you see the rudder painted and my first attempt to use the lozenge decals, I was not too precise cutting away the excess part with the scalpel, I am worried when I'll have to make the more extensive trimming required by the fuselage livery...
Tail planes:

same home made control horns...

the stripes were painted using Tamiya Flat black and it was a nightmare, there are a few basic colours from Tamiya that are impossible to use with the brush, this is one!
In any case the result is OK to me and will spray an overall coating of Humbrol satin transparent varnish to get an even finish. The white is Mr.Kit Italian Navy Off white which is a really nice tone, it has a satin finish.
Wheel discs:

I will spray the wheels with satin transparent before painting the tyres and putting a lozenge decals disc on the inner side.
Propeller:

I should have used a lighter tone for the basis (I used yellow ochre but perhaps is too warm ...)
Cowling:
After painting it off white, I cut some triangles (4 mm basis - 6 mm height) to mask the white parts

and painted with Tamiya Flat black with the same problems.

Here some touch up as well as the satin transparent coating will be needed
Wing:
Control horns applied

Then I made some colour essays:

To make the streaking more evident, I tried to paint a drybrushed base of Tamiya XF54 Dark Sea Gray (left half of each circle). On each circle I then painted the chosen colour diluted with water (not too much) using a stiffened brush:
44) Tamiya XF64 Red Brown
45) Citadel Goblin Green 61-42
46) Mr.Kit 07 Flag Green
47) Citadel Ice Blue 61-36
48) Citadel Warlock purple 61-28
I didn't like 45 so I tried 46 which I liked most. The other colours appear good to my eyes.
Here is the final result on the upper surface of the wing...

XF64 Red Brown is flat, while Mr.Kit 07 Flag Green is satin, so I will spray all over the satin varnish once the wing is completed and the crosses are in place.
I also started detailing the cockpit:

OK that's all for now, stay tuned!
