Just spotted this thread ... Who is the manufacturer, Wayne? Nice work!
Years ago PDQ offered at least a P-51 and Yak-9 (Matt Kania designs) in 1/2-A size. They also offered them in .35 size, slightly smaller than, and prior to, the Sterling productions.
If there is one old kit that has sentimental value to me, it's the smaller P-51. I mixed together all the dope I had - couldn't afford to buy more - painted it with the dull gray mix, flew it with a Cub .074. I was completely thrilled to do several consecutive loops without crashing it.
Oh, the memories! Oh, what little it took to thrill us!
