About this Plan

Zoegling. Free flight glider model. Primary glider.

Quote: "A towline glider modelled after a German Luftwaffe primary flight trainer.

Probably the simplest and safest of all the training planes ever built, the primary glider trained thousands of aviators for the German Luftwaffe, introduced many of todays famous aircraft tycoons and flyers to their first flight experience, and should truly be classified as a famous aircraft.

This glider will make a good project for the beginner and yet can challenge the experienced model builder because there is no limit to the amount of detail that can be worked into the pilot, controls or finish. The plane is a real floater. The areodynamics of this ship allow for slow sink without flying half way across the countryside. It can be towed very easily because the low wing loading makes for good control on tow at slow speed.

We use the high-start launch with about 75 ft of 1/8 rubber with 150 ft of string. Just pull the ship back, release, and watch the slowest longest tow you've ever seen. The little primary will dip it's nose and release before beginning the slow float back to earth. As the ship glides near you can hear the gentle swish of the wind past the taut bracing. For a spectacular crowd pleaser try two primary's on the same line separated by about two feet. The tow is entirely normal and we have never had them crash. Like to give it a try? Then let's get to work.

As can be seen the construction is about the epitome of simplicity. To make the fuselage cut the top and bottom main pieces to size first. Pin them to the plane and cut all the cross braces slightly oversize so they can be sanded to the exact angle of fit. The pieces are assembled temporarily with pins. When the fuselage is finished the pins are pulled out and each vertical piece is sanded to a streamline shape. Simply smooth the horizontal pieces. After fine sanding we are ready for the staining process.

A small can of mahogany stain is left standing upside down for a few days until the pigment' has collected on the cover. The can is then opened, be sure you turn it right side up first of course, and one small dab is placed in a small bottle of thinner. Mix well and test it on a piece of balsa wood. The result should just color the wood.."

Quote: "All - These scans are from my issue of 'How to get started in Model Building and Flying' ...the Zoegling and Lil Louie were published in this book as well as in Flying Models. I don't have or know the issues they would be in other than this book by Flying Models. enjoy, jeff "

Originally published with general layout shown at 25% and ribs shown at 100%, this has now been scaled to a fullsize plan, thanks to Pilgrim.

Note the article and plan pages as published in 1957 used the spelling 'Zogling' as opposed to 'Zoegling', or indeed 'Zögling' which is (we think) the correct German spelling.
