I AM NOT SELLING A KIT, only a new, full-size copy of my original PLAN + construction article to build a 41" 1951 RINGMASTER UC stunt model for yourself. 

This 1951 RINGMASTER Harry Williamson construction article and PLAN for an outstanding straight-chord, no-flap Old Time Stunt design was one of Pop’s favorites since obtaining this full-size PLAN 69 years ago at age 15.

This is NOT the same model as the old Sterling Ringmaster kit. That model had a swept-forward wing trailing edge. This RINGMASTER by Williamson has a full length straight wing chord. So, this Williamson design is not the same one at all. I show a picture of Pop’s old STERLING CUSTOM RINGMASTER hanging in the middle of a bunch of models in the workshop; and a picture of the STERLING CUSTOM RINGMASTER model from the label on an old kit.

With this straight chord on the 1951 RINGMASTER, you'll only need to make one master wing rib pattern and you can then cut out all of the needed ribs from that. All of the fuselage bulkhead patterns are clearly shown on the PLAN. Since this 1951 Old Time Stunt design does not have flaps, it is quick to build.  

I AM NOT SELLING MY OLD MODEL ON THE WALL, just a new copy of the 1951 OTS RINGMASTER PLAN.
