Airframes, I might just start to build models again as you suggested. This forum is motivating as much as educational.
In fact I have one kit that I bought but somehow never came to build it. Its Revell's Me 262B-1a/U1 in 1:72 scale. Anyway, I postponed this build until I will be able to build it right (and it passed 10 years since then already). You know, painting it with appropriate colors and with airbrush (all my previous models were hand brushed), weathering, etc. This model would be interesting addition for "Defense of the Reich" Groupe build I think, but it's too late now. I would also like to try to build models in 1:32 or 1:48 scale, since all my previous ones were 1:72.
I think I will wait until "Eastern front" Groupe Build comes along and maybe participate in that one. Until then I will use my time to learn more "secrets of the modeling trade" on this forum.
