Bristol Bullet Scout (oz884)
About this Plan
Bristol Bullet Scout Type D (Bristol Scout). 1/12 scale 1914 scout biplane, for rubber power.
Quote: "Designed by Capt Frank Barrnwell in 1914, the Bristol Scout was the first single seater scout to go into production during the 1914-18 war. It went into service with the RFC towards the end of 1914.
Simplicity of construction has been the keynote in the design of this machine, and it therefore an ideal subject for the newcomer to the ranks of scale flying biplane enthusiasts. The only parts which are likely to cause any difficulty are the engine cowling and dummy rotary engine, which like the wheels, are built up from paper-mache pressings. In any case, the builder can very soon substitute components made from balsa if he is unfamiliar with this method of construction.
The weight of the model complete with an eight-strand motor 27 in long is 11-1/2 oz. CG should occur at a point 0.8 in aft of the lower plane front spar, and in order to attain this it was found necessary to attach 1-3/4 oz of ballast to the underside of the engine mounting structure.
With two hundred turns on the airscrew the model was pushed off from a stretch of runway and became airborne after a 20 ft run. Rising to a height of about 18 in, it flew the length of a large hanger before touching down. For normal hand-launched flight I found it was advisable to increase the tailplane incidence by 1/8 in at the leading edge.
In an attempt to reduce the amount of ballast required, I decided to fit a Moore Diaphragm with the following results..."

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 (oz884) 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/Bristol_Scout
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.
Do you have a photo you'd like to submit for this page? Then email firstname.lastname@example.org
User commentsFar be it from me to have a go at Eddie Riding, but is the title "Bullet" correct here? I think maybe this here is a scale model "Bristol Scout type D", and the "Bullet" was a later racer designed after the war.

Can't help with the name puzzle but the plan on OZ was originally published in the December 1945 issue of Aeromodeller along with the attached article [supplementary file]. The conversion details from rubber to power were in the January 1949 issue.

* 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.
