My personal 1:33 scale want list includes dozens of aircraft, mostly jets, that were never released, were released but lack sufficient detail, were released but not in the livery I want, or were released but went out of print. After 20 years of waiting, and seeing all the successful designers here, I finally decided to take matters into my own hands. Learning Blender requires hundreds of hours of effort (and extreme frustration) but once one learns to fish, one has fish for life.
I may start with an F-107 Ultra Sabre. My heart longs for an Arado E.555 but something that large and complex demands a lot more experience and a much larger display case since it would have a three foot wingspan. (I had to look it up since my memory continues to fail.)
