Description

The PT 20 trainer was first published in RCM magazine, then offered as a kit by Great Planes.  This kit matches the Great Planes plan on outerzone rather than the RCM plan.

Although the plan shows the engine mounted on beams, I assume that most builders will prefer to mount the engine on a nylon mount attached to the firewall, so that’s how the parts are made.  When you build your plane, the leading edge and trailing edge are both 1/2″ thick, and the aileron is 1″ wide.  For three channel operation, simply glue your aileron stock to the trailing edge stick.
