wow, you like this, it is not so colorful marking, but I will build all Nieuports and so the 21 must part of this, ski and russian markings make it a little different, and I tried to make a big difference of chrome metal parts and flat alu fabric.
Propellers are a significant part of a biplane with two different posibilitys, only one wood color ore light/dark striped. For the stripes you to mask and paint the two tones, for a homogen wood you need light base, than metal primer, oil color and a hard brush and metal primer, real easy to handle.
