We take you back now ... to 1944
Dave Shrum of Roseburg, Ore., recently finished this spark-ignition-powered Tethered Trainer, which was built from 1944 Air Trials plans of the design by Earl Clayton. It's one of two TT's known to be flying in the Northwest. Floyd Carter of Eugene, Ore., built one some years ago that was featured on a Northwest Regionals T-shirt.
Below are some additional pictures of Dave Shrum's TT project. All photos by Dave Shrum except where noted.
