About this Plan

Knight Twister. Gas U-control by Walt Schroder from 1940's Air Trails.

Quote: "The Twister, designed by Vernon Payne in 1932 has always been of interest to builders because of its small 15-foot span and beautiful lines.

This control-line Knight Twister is a compromise between speed models and the so-aptly named 'Goats'. The prototype's well known lightplane history and the opportunity to combine exciting scale-model possibilities with a reasonable rate of speed, make her an ideal project for scale control-line fans. Simplicity is the keynote of the entire construction The sturdiness and flyability of the plane will permit the use of a Forster 29 or 305, or even any other small, class C motor.

The use of a biplane with its increased wing area permits the average control-line flyer to land this model without incorporating all sorts of complicated gadgets to blip the motor, throttle control, or spark control. Its ability to glide the model after the motor cuts offers all sorts of possibilities for stunting and regular flight maneuvers.

Fuselage. A conventional crutch of 1/4 x 1/2 is used. Glue all upper formers in place while the crutch is drying, then install the control system. Make a platform of 3/32 sheet and glue it on top of the crutch at the center of station #3. The control fulcrum of 3/32 in plywood is mounted on the platform, with an ordinary #9 wood screw acting as the anchor and bearing point of the fulcrum. Be sure to use a small clipper burr between the head of the wood screw and the control plate, plus two copper burrs between the bottom of the control plate and the plate platform.

Glue all stringers and the front nose block in place before planking the model with 1/8 x 1/4 soft balsa planking..."

Supplementary file notes

Article pages, text and pics, thanks to BillW. Also, previous scan version (this is not a fullsize plan).


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

    ScaleType: This (oz457) 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
    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.

* 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.
