Thanks Des, yes, my eyes asked for an integration to their salary …
Here we go,
I started studying the single pieces, detaching them from the sprue and trying to get rid of the Balkenkreuzen and of all the struts and structures moulded in the pieces.

The picture above shows the underside of the top (on the left) and middle (on the right) wings.
The arrows indicate the intervention points.
As you can see, the struts are unacceptable and the holes where the struts should be fixed are replaced of those square boxes.
The extractor marks are very visible. I will try to fill them with successive coats of Mr.Surfacer rather than using putty...

Here you can see underside of the bottom wing. Also here the strut insertion points are shaped as square boxes. I removed one (left in the pic) and understood they are a sort of socket.
The holes are OK and will be used for the new struts that I will build from scratch.

From this picture (bottom wing after the surgical elimination of the two boxes) and from the previous one you can easily notice that the ribs are not designed on the underside of the wings and I would like to have them also here...
I need your advice to find a solution...

Here I closed the fuselage, as you can see the cabane and the undercarriage struts must be cut away and replaced.
In the meantime I took off the wheels that shall be reused.
The squared piece of red plastic you see near the detached wheel is a slice of the pin insertion point that is on the internal side of the wheel... I removed both of them.

This is the middle wing, you can also see the underside of the tail planes which misses the ribs as well.

The upper surfaces of the three wings: on the top wing I tried to remove the crosses and in the end I just removed the ribs (s**t!!!)

Undersides are shown here after removal of the wrong parts.
Wheee it seems I underestimate the effort on this job!!!!
But that's the fun I get out of it!
BTW I have gone forward today, before showing new pics, I would like to ask advice on some points:
- Did the Fokker triplane have an Insgtrument panel? From my search it seems it hadn't, does anyone confirm? I read there was a single instrument attached to a transversal strut...
- Which colour should be painted the inside? I painted wood the plywood triangle on both the sides of the pilot
- Which colour to paint the tubular structure?
- Which colour to paint the struts? WHere they wood onr painted same color of the aircraft? I read someimes they were in olive drab sometimes in turquoise...
Thanks for helping!
