Buhl Bull Pup (oz7453)
About this Plan
Buhl Bull Pup. Radio control semi-scale model for .40 power.
Quote: "Some years ago I had acquired a collection of Berkeley kits (now out of business) and was intrigued with a kit called the "Buhl Bull Pup." It was 1-1/2in to the foot and I thought it would be very interesting to see how this aircraft design would work out in a larger R/C size. With pen in hand I started with a few mathematical equations and before I had realized how far I had gone, I was constructing it in 2-1/2in scale. I am somewhat lacking in the history on this airplane, but I did find out that it was one of the classic planes of the golden age, built around the 1930s. It had a very unique sheet metal fuselage and tail surfaces. Most of these planes were finished in natural aluminum wherever metal skin was used and the fabric wings were sprayed aluminum to match. I chose the color scheme because I remember seeing one of these planes published in Sport Flying some years ago. It was of identical color, using a dark blue fuselage, and cub yellow for the wings, stabilizer, and elevator. It would also be a very attractive plane in chrome MonoKote.
As you can see by the photos, it's not a hard or complicated plane to make. I started by building the wings complete, including the root rib, and then cutting out the section to install the window assembly. If you first build the entire wing, you can be assured of a true wing before cutting into the root rib for this construction area.
You may have noticed that I have added some improvements in the wing since some of the photos were taken, as I found it was necessary after the first tests to insure a more rigid wing panel. Some builders might wish to eliminate the wing window, but I suggest it be used as it was one of the outstanding features of this airplane..."

ScaleType: This (oz7453) 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/Buhl_Bull_Pup
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.
