""Let's Go Fly An Orc!"" Topic

no, but only because I don't focus on that sort of gaming.

For GASLIGHT, I took the WFB Birdmen of Catrazza and glued ACW Zouaves under them. I added strange jewelry to the top to look like steam (of course!) propulsion.
Their main useful feature was that they drew fire away from other friendly units.

Yep. Dwarf gyrocopters for Warmaster. Fun units!

Nope, no technological flyers among my fantasy forces. There's a couple dragons, a winged humanoid, and a few ghosts, who more-or-less fly but presumably count as magic.

GW's Man O War — squadrons of gyrocopters and balloons, as well as eagles and dragons and whatever else can fly.

I took a bunch of my Caesar 1/72 scale Goblins, hurling Molotov Cocktails, and I cut them from their bases. I took Schleich Fruit Bat toy figures, mounted them to 50mm square bases, using large pins, Hot Glued to the base. I bent the pin's pointy end, to skewer the Bats in their bellies (plastic bats cannot feel pain, so no harm, no foul). I notched the necks of the Bats to allow the Goblin's legs to fit around it, gluing them into place. Folder of images here.

Now I have Goblin Bat Cavalry hurling fire bombs. They're not terribly effective in game terms, but the visuals are spectacular. Cheers!

Get back to me when aerial units don't require poles running down to the tabletop or lines hanging from the ceiling.

They aren't poles! It's brass tubing!

Like Parzival and miniMo said, you can never have too many Dwarf gyrocopters

I use barbecue skewers made of bamboo: inexpensive, versatile, easy to cut, they take all glues and paints very well. Cheers!
