First up is Zvezda's Il-86:

The decals in this kit look terrible! So my first question is easy: what are my options for replacing them?
Next up is a bit of an impulse purchase that I'm already regretting, but c'est la vie, eh? The old Otaki Do-X in a Matchbox box:

Decals here aren't great either, but there aren't many, and I'm not especially bothered about them. The real issue is that most of the props (12 of them!) are broken. Any hopes of finding some replacements? Otherwise, I might have to do it in-flight, and use clear discs to simulate spinning props. I don't normally like that look though.
All answers on the back of a well-crafted forum post, please! They'll all be gratefully accepted.
