Dormoy Bathtub (oz4732)
About this Plan
Dormoy Bathtub. Free flight scale model for Cox Pee Wee engine.
Quote: "In 1923 Ettienne Dormoy, then working for the Army Air Force at what is now Wright Field, designed and built this little ultra-light for the 1924 Lightplane air races. It's novel engineering has intrigued the aviation world ever since.
A good deal of research has gone into this model. We believe the plans are as near scale as is possible. Unhappily, Mr Dormoy had no carefully saved three views for posterity. He did have some photos and did compare my attempts at an earlier three view.
Within practical limits, the model has the same type of structure as the original. Fuselage and fin are aluminium sheet as was the prototype. Wing, horizontal tail and rudder are built up balsa structures. with tissue covering. Main frame and landing gear is a soldered steel wire assembly. Fin and tail are held on with wire wrapping as on the original. I would recommend .004 thick aluminium lithography sheet if you can get it..."

ScaleType: This (oz4732) 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/Dormoy_Bathtub
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.
