The RC Stringless Wonder feature article by Joe Haas in MA appeared as a construction project and plan set. If you access the AMA plans service you'll find a brief description. Purchase of the plan set includes a photo copy of the article pages. The project is a flat-foam tribute to the original design that included an all foam scale and 150% enlarged version. Both used RC systems from the ParkZone Ember and P-51 respectively.

Have fun!
