About this Plan

Ringmaster S-1. Control line profile stunt model from Sterling.

Quote: "Attached is a plan file for a Ringmaster S-1 which was kitted by Sterling Model Co in 1950. This is the profile one designed by Matt Kania. The original kit did not have an actual plan but only an assembly instruction sheet. The plan was made by tracing the parts from a kit and forming them into a CAD file and subsequently converted into PDF file. The file will print a full sized plan if printed at 100%. This is in 'public domain' so anyone can copy and use the file."

This is a modern redrawn plan in PDFvector format.

Many thanks to Tim who sent in the colour photos of his nicely finished Sterling Ringmaster [pic 003].

This is an S-1 modified by long time builder Cliff Betz, with an I-beam spar and half ribs [more pics 004].

I changed the landing gear on this S-1 to wing mount and now I can make a decent landing [more pics 005-007].

I remember mine. I did so many "figure 9's" with it the center of the wing was solid 5-minute epoxy.
Ran a Johnson Combat Special with a 7-9 prop as a rat racer.

I built and flew this kit way back in July of 1968, just after being discharged from the U.S. Navy.
I had a ball flying that plane three or four times a day, two or three days a week. The plane met its demise when some younger kids were watching me fly it but became more interested in a buried cabled, sticking it up from the ground about four feet.
I saw the cable about one second too late and ripped off everything on the starboard side of the aircraft! Wham, no more plane. It was a lot of fun to fly. I didn't try to rebuild her because shortly after that we moved from Portsmouth, VA to Lebanon, IN where I became interested in R/C airplanes.

I have recently taken up control line flying again (my main interest being Free Flight) and was told about the October Ringmaster event. I downloaded the plan from Outerzone and made the model [main pic, 015-017]. I am using a 1oz Sullivan tank with an OS 25 Fx. so I can chalk up a number of short flights for this event. The model performs well (fairly quick) and I intend to attach a larger tank for general aerobatic sport flying. Thank you for supplying these plans.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
