Push Rod (oz2695)
About this Plan
Push Rod. Free flight power model with twin-boom pusher layout. Bantam power shown. From Model Airplane News Oct 1950.
Quote: "Push Rod was primarily designed as a sport and all-around flying model, with no intent on contest fame, unless the Clark Y airfoil the model now carries is replaced with an airfoil of more suitable contest qualities. The basic design has been used by the author for a number of years, but construction of Push Rod was abruptly curtailed at the request of the government. Upon returning to civilian life, what had been built of the model was found in a heap of balsa and dust. Starting from scratch was more than necessary.
Push Rod sports ample wing area (400 sq in of it), with a span of 55in. She may be powered with engines of .19 to .29 cu in displacement; the model shown in the photos sports an OK Bantam. The pusher design is easy on props, while the wide spacing of booms allows ample elbow room for starting the engine. The tricycle gear saves wear and tear on the booms as well as on props and adds a measure of class to the model. The ship has an unusually flat glide and is really an eye-catcher on the flying field.
But enough about Push Rod history - let's buckle down to building her. Each modeler has his own system of starting construction, but the author strongly suggests following the procedure outlined here. Study the plans carefully, paying particular atten-tion to the landing gear installation and the method employed in fastening booms to wing center section. The entire ship is built of medium-hard quality balsa.
Completely familiarize yourself with the drawing, and after having enlarged the necessary portions to full size, start construction of the booms. The sides are 1/8in sheet balsa, with 1/4in sq spacers tapered to 3/32in at the tail end. Cement well to form a box-type section. The booms should be left longer than needed, and trimmed prior to assembly..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
