I AM NOT SELLING A KIT, only a great, new copy of the classic PLAN and construction article for Bob Palmer's famous twin-rudder MARS UC stunt model.

This 49" span UC stunt model was so well designed that it was twice kitted even as an RC model! A Fox .29 or .35 will do just fine in this dependable design.

As a BONUS I include a nice bio of designer Bob Palmer.
