I know this is a tad OT, but on the weekend my Brother had his annual fly-in/BBQ, this was held at his farm airstrip located in central Victoria, Australia.
On Saturday I was lucky enough to get a ride in a genuine WWII veteran War-bird, no not one of your fancy pants Spitfires or Mustangs but a true hero of the skies, a Piper L4-J Grasshopper.
Being the passenger I lucked out and got the front seat, in an all to short but none the less enjoyable experience.
As you can see in the shot’s below she is finished in ETO colours, although her actual service life was in the Philippines.
I have always thought that ARMY Co-Op aircraft such as the L4 Grasshopper, L5 Sentinel and Fi 156 Storch would make excellent stable mates for 1:18 armour.
Guillows do make a 1/18th scale free-flight/electric model of a Piper Super-Cub which should be able to be converted back to represent an L4, I will have to investigate, see I knew I could put an OnT spin back on this thread.
The only plane I could think of is the Zero.
