Here is a shot of that "civilianized" O-1 Bird Dog that I was working on in a previous post:
I used a fine Sharpie pen to make the thunderbolt on the tail and the lettering on the wing. There was no way I was going to attempt the lettering along the fuselage. I decided not to put a magnet on the bottom of this one for now. It will look nice sitting on the tarmac of the airport I plan to build.
