Elias Airsport (oz11439)
About this Plan
Elias Airsport. Peanut scale model.
Quote: "This saucy parasol has enough wing area to compete with the Fikes and Laceys. Elias Airsport, by George W Meyer.
IN MY SEARCH for an aircraft suitable for a peanut scale with gobs of wing area that would compete with the Fikes and Laceys, I came across this aircraft in the 1929 Aero Yearbook. It is the Elias Airsport with a 28 ft wing span, 7 ft chord, and aspect ratio of four-to-one. It is ideal.
After Lindbergh's epic flight in 1927, the industry was booming and the manufacturers were trying to design aircraft that would be attractive to the airminded youth of the period. The Elias Company, of Buffalo, New York, had started out in 1917 as a government contractor of military aircraft and, after the war, built a variety of commercial and military aircraft.
With the demand for an economical, easy to maintain aircraft, Elias produced the first convertible 2-place, side-by-side aircraft, the high-wing Airsport EC-1. A cabin section could be buttoned on in a matter of minutes to produce a closed aircraft known as the Aircoupe - an option that could be purchased at a small additional cost.
The EC-1 used construction which included a chrome-moly steel-tube fuselage, with most parts interchangeable from right to left - exceptions being the landing gear vees and the upper wing panels. The landing gear shocks were steel coil springs inside the shock struts, which did not require maintenance usually required for air or oil shock struts.
The EC-1 was exceptionally easy to fly. If left uncontrolled in an abnormal attitude, it would right itself almost instantly and resume a normal flying attitude. You could put the machine in stall with full power, remove your hands from the controls, close the throttle - and the EC-1 would gently settle flat and go into a glide. The EC-1 could be forced into a steep dive with full power, hands removed from the controls, and would come out into a normal flying attitude.
Fuselage: Make two fuselage sides from 1/20 contest-grade balsa, one on top of the other, then separate them back to the tail post with a razor blade. Add the cross braces and be sure to keep the fuselage straight and square as you go along. Bend the landing gear out of .025 music wire and sandwich it between two pieces of 1/16 balsa, then install in the fuselage. Make up the landing gear struts from 1/64 plywood. Make the shock strut from 1/16 round balsa with a piece of paper wrapped around the strut to simulate the shock. Glue the landing gear to the fuselage, but do not glue it to the wire landing gear. This takes up the landing shocks and will not break the landing gear or fuselage.
Make the rear rubber hook and tail skid from .020 music wire; bend and glue it to the tail post and the rear of the top longerons. Form a small loop at the end of the tail skid, so you can install the pin in your winding stooge when using a rubber winder. Leave open the area on the bottom of the fuselage so you can install the rubber motor. This rear hook is the design of Dr John Martin, of the Miami Indoor Model Club.
Add the bulkheads to the top of the fuselage and cover the front section with 1/64 soft balsa sheet. Now cover the top of the fuselage from the cockpit back with light-weight Japanese tissue (I use light blue) and give it one coat of thinned nitrate dope. Add the 1/64 balsa sheet fairing be-hind the cockpit; glue to the bulkhead behind the cockpit and to the paper on top of the fuselage.
Make up a dummy 6-cylinder (2-row, 3-cylinder) Anzani engine. Make the laminated balsa crankcase from 1/8 soft balsa. Make the cylinders out of the corrugated section of 1/4 flexible plastic elbow straws. Make the intake and exhausts of paper tubing by wrapping paper around a 1/16 rod. Glue and slide off the rod. Put 1/16 balsa disks on top of the cylinders. Make the rockers from scrap balsa and the single pushrod from tiny flower stems available at art and hobby stores. Glue with Hot Stuff all parts of the engine that attach to the cylinders. This is the only glue I have found that will stick to the plastic soda-straw cylinders..."

ScaleType: This (oz11439) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Elias EC-1 Aircoupe
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

User commentsHow can someone design, build and FLY such a pretty machine and not be a good person?

* 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.
