Yak18: Vance Mosher of Vanguard Plans offer a T-28 plans and/or kit. It's 1/5 scale and really, really nice. You can check out a build on RCScalebuilder forum under Designers, Vanguard Plans, My T-28 Build. Anyhow, check out Vance's website for more information. Also I think RCM Plans still offers Dave Platt's T-28 article and plan and perhaps you can have a kit cutter laser-cut the parts (or cut 'em out yourself). Hope this helps.

Soft landings.
