I figure I'd better get in with a WIP topic in case someone else has the same idea as me and claims I copied them :-)
This is very preliminary, but here's what I've got so far.
Mini Crop Duster.
Features (hopefully I can get them all in!):
"Remote" controls
* Retractable undercarriage
* Engine and propeller
Local controls
* Flight surfaces
* Steerable tail skid/wheel
It's going to have to be yellow, because most of my other colours are locked up in other models at the moment, and since crop dusters seem to be predominantly yellow tail-draggers (albeit with fixed undercarriage), it seems a natural choice.
If all goes to plan, I'll finally be able to find a use for the panel fairings from 8455!
