I've painted this Gladiator in the Dark Earth/Dark Green livery it would have borne for home service at the beginning of World War II. I don't know if Gladiators were painted the half-and-half black and white on their undersides* that other fighters wore; but since, as a tabletop gaming model, it will almost never be seen from underneath I haven't worried about it at all.
[ * They were, apparently ]
It's been printed in FDM on my Ender 3, and the surface detail on the fuselage ribbing is pretty rugged. I think I could probably get better results by rearranging its orientation on the print bed and printing it in a single piece, though that would mean a bit of pre-supporting of the STL in Blender for the sake of reliability. I may or may not ever get around to doing that. That should also help with the crappy printing of the undercarriage.
Later...
I learned that the Gladiator followed the standard Fighter Command practice for their lower planes, which was to have the port wing painted white and the starboard black. So I went ahead and painted it as such.
I believe it was supposed to facilitate IFF from the ground, which it doubtless did, but it also made the aircraft stand out like sore thumbs to opposing fighters and enemy AA gunners, and the practice did not last for very long once combat began in earnest.
The model is hanging off one of my magnetic perspex flight stands.
Later still (several days later)
Another Gladiator, this time painted up for use in the desert or Mediterranean.
This was printed as a kit, and it printed absolutely terribly, mainly due (I think) to the resin I was using. It developed a multitude of cracks, and the dimensional instability of the resin means that none of the components fitted well together. Add to that its brittle fragility, and you don't end up with a good model in any way.
I was in two minds about whether or not to even bother finishing its paint job, but I have. It will do as a gaming marker, but that's about it. I did another much better one-piece FDM print that will most likely end up replacing this one.
I've been playing around with Photoshop's Generative Fill tool, which makes getting rid of things like flight stands an absolute breeze. And just to keep him company, I've added a happy little Falco to the picture. The backdrop is an aerial desert scene I found somewhere on the internet and printed on my fairly crappy inkjet.
