Love it! Keep the project coming. I have some air support for my games, too. I found I liked the die cast better than the plastic kids. My days of putting together a model with dozens and dozens of tiny parts are loooong since over! 
I try to keep an eye out at flea markets and such to get a good price.

Mike, I completely agree, but have struggled for diecast items in this scale, and at the right price

The air support has come about in different ways.
The hunter model was found in a model shop, costing only £10.
The helicopter models were £10 each, but I did buy one for only £3 a few years ago. (Wish I’d bought more at this price).
The push/pull Cessna was around £10 from eBay. Plan is to remove what’s left of the undercarriage, mount a couple of cannons on top of the wings, then a repaint.
