About this Plan

Ruler. Free flight power model, for OK .49 engine.

Quote: "History: 2nd place, Class C Open Cleveland National Races, 1 September 1941. Published by Scripps-Howard Newspaper, September 1941. Span 66 in, area 580 sq in. Ruler, by John W Grega."

Quote: "While searching for the subject of this issue's Rare Old Timer design, I scanned across page 18 of John Pond's Old Timer- Nostalgia plans catalog #22 and there it was - a New Ruler with twin rudders and a flat center/dihedraled tips wing. I searched no further. There are three features which really characterize many OT designs - an open cockpit/pursuit type fuselage, twin rudders and a flat center panel wing with dihedraled tips. The Ruler is one design which embodies all three features.

The Ruler was designed by John W Grega Circa 1939 -1940 and resembles the New Ruler (oz534) and American Ace (oz4697) designs of Henry Struck. As a matter of fact the original Ruler was scaled from the 54 in Berkeley Kit of the American Ace utilizing the pursuit type fuselage with open cockpit, twin rudders and an NACA 6409 airfoiled wing with flat center panels and dihedraled tip panels with slots.

The original model of the Ruler won second place in class C Open at the Cleveland National Air Races in September, 1941. It had a length of 40 inches, a wing span of 66 inches with an area of 580 square inches and weighed 2.5 pounds. It was powered by an OK 49 and, as Ed Clarke - editor of the National Junior Aviator wrote in his article about the Ruler: if you're looking for an old standby gas job, here's one fresh from the fields of competition..."

Update 04/08/2019: Added article, thanks to Pit. This comprises 3 separate pages from 3 distinct issues of SAM Speaks (March 200, July 2000, March 1993), which all reference the Ruler.

Quote: "Hi Steve, from my source it was published in San Francisco Chronicle 1940, but that may not be true. In any case attached some art. from various Sam Speak newsletter. Pit"

* 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.


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.
