My current project is this limited run Roseplane resin kit. This is not the best quality kit I’ve come to expect from them. However, it does provide an excellent base for detailing.
The V-25 was one of several variants of the Fokker V-17. The V-25 utilized a Fokker Dr.1 fuselage and tail section. The same Oberursel radial engine as well. None of these variants were put into production so very little reference material is available.
I plan to build mine as a what-if model in production warpaint markings.
Here is one of the three actual photos I found of the aircraft.

The Kit drawing:

The kit components (no box provided)
The Dr.1 photo etch interior is from VLE models and I think is included with the Roseplane model.

I decided to add a few more detailed parts borrowed from the extras in an Edward Fokker D.VII kit. The undercarriage struts are from an ESCHI Fokker D.VII
.

I had to radically thin out the fuselage interior if I intended to use the photo etch parts. I was still skeptical if the PE would work
I accidentally ground a hole through the fuselage wall. This was patched with thin Evergreen sheet and putty.

After all that I primed the interior and applied some off color four color lozenge decal. This was to represent the reverse side of the exterior lozenge. I also scratch built the interior wooden fuselage formers.

I was unable to make the PE framework fit so only used the flooring details.
.

Here’s the construction ready for primer. I recently bought a CMK razor saw and made quick work of cutting out the ailerons. Why haven’t I tried this earlier?
.

I also ground out channels in the wings and added half round to the ailerons for better fit
I imagine that if this aircraft were to have made it into production, then the wing surface would have been painted the same as the wooden Fokker D-VIII. Current theory suggests that the wing was streaked green and brown on the upper surface and light blue and mauve on the underside.
I started with a base of wood tone.

.

Then I streaked on Model Master dark green. Taking care to leave some wooden tone visible. I then applied Flory dark clay wash in the same angular pattern.
.

The underside was streaked with Model Master French light blue and Poly Scale WWI purple. Then a lighter wash of Flory dark clay applied.
After it all dried, I brushed water over the surface to remove excess Flory wash.
.

I’m liking the end result.
Thanks for looking in!
