About this Plan

The 29er. Free flight rubber (non-scale) model.

Quote: "The 29er was designed especially for good flying and realistic appearance. It is easily adjusted for long, high flights indoors and out. You don't have to be an expert builder to get flights of 25 or 30 seconds, and if you're a contest genius you should aim at flights several times that long.

Although it is not a scale model, the 29er looks so realistic that even experienced modelers often ask whether it's a Heath, or a Fairchild, or some other sport parasol of the 1920s. If you have never built a flying model before, than the 29er is a little too difficult to start on. But if you've completed a balsa kit or two and would like to try a fine 'sticks-and-paper' flyer, then let's get started.

FUSELAGE: Build two fuselage sides directly over the plans - one on top of the other. The wedge-shaped pieces under the tail and the N-struts under the wing are built as a part of the sides. Don't leave them off. Round the corners of the firm 1/16 x 1/8 strut piece, before cementing in place. When the fuselage sides are picked up from the plans end eeparated, lightly cement the 1/16 square temporary braces diagonally across the outer side of both strut assemblies. They will strengthen the struts to prevent damage to them while you are completing the fuselage.

Join the two fuselage sides with formers F-3 and F-5 first. When these joints have dried, cement the remaining cross members and formers in place between F-3 and F-7, top and bottom. Let this assembly dry thoroughly before completing the front and rear ends of the fuselage. The sides will have to be cracked slightly at former F-3 to allow the fuselage to narrow down near the nose..."

Quote: "Hi Steve - Here is Paul McIlrath's 29'er from Sig Air Modeler magazine issue July-August 1967. The two page build article and a half size 'before cleaning' page is included. This was the last issue of this excellent, short lived (only a year) magazine. A great illustration of the 29'er was featured on the cover, as shown."

Update 13/05/2019: Added SIG kit instructions, thanks to wanderings-ds at https://wanderings-ds.jimdo.com/sig-ff-kits/. Note these are from the SIG kit ref FF-21, and show a slight variation from the magazine plan, with additional stringers to make a more rounded fuselage top decking. Printwood patterns appear on page 1.

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.
