I am currently applying color pigments to the chassis to make the dirt marks look a little more realistic.
I am using model pigments from the manufacturer "AMMO" for this.
I'm not done yet, but here's a picture to give you an idea of how it will look:


You can see the axle piece nicely in the center of the wheel.
This was scratch-built afterwards - it was very unattractive straight out of the kit.
It was relatively easy to do:
I took an Evergreen round rod with the right diameter, drilled a hole through it, then drilled a 0.2 mm hole in the side and pushed a hot-drawn plastic sprue through it as a cotter pin and cut it to length.
The cotter pin is held in place simply because the hot-drawn sprue is slightly thicker at one end than at the other.
The paint now holds it in place anyway.
The washer between the wheel and the axle pin consists of a 0,13mm thin Evergreen plate that has been punched out and drilled in the center.
The reproduced axle ends were painted with 50/50 semi-gloss black and matte black.

The claw brake also had to endure a bit of makeup.
Apparently, it was used to brake our Roland D.II hard on the landing field shortly before.
The ?dirt? is actual dirt, straight from the garden?stuck to the claw with heavily watered-down white glue.
The torn-out blades of grass are also part of the garden soil.
