Beaufighter I (oz11936)
About this Plan
Beaufighter I. Rubber scale model twin WWII night fighter.
Quote: "HEREWITH are the plans for building Britain's latest night fighter. Several original constructional features have been embodied in the design, resulting in a very robust model which will stand quite a lot of 'man-handling'. No super-duration can be expected of the Beaufighter - in fact, the longest flight to date has been one of 26-1/4 seconds. The model is very tricky to trim and fly, but if the instructions are followed to the letter, reasonable results can be expected; it will also give hours of building enjoyment, and will enable the builder to conduct various experiments in the 'twin engine scale model' world.
Fuselage Construction: This is the most difficult operation and very great care must be taken to ensure accuracy. Cut out formers, keels, etc. Insert keels (top and bottom) into the notches on the formers, and glue in position. Next mark the former positions on the 3/32 square longerons and glue into notches on formers (top longerons are fitted first). Steam the top and bottom longerons to take up the curves forward of No.3 former. Glue all 1/16 square stringers (birch if possible) in the former notches.
Note: Fuselage must be trued up from time to time in these operations. The fuselage is now covered with 1/32 soft sheet balsa 'planked' (ie using 1 in x 1/32 in strips of wood).
Note: Planking is commenced after the windscreen and cockpit covers have been glued in position. The part of fuselage extending from former No.3 to former No. 5 must be covered last, and when this is done the bottom longeron must be cut at these two formers (see notes on plan) so that it falls away.
The centre-section spars are now fitted on to formers 3A and 4A and the ribs are glued into place. This operation may be a little trying, so take care with the building. Cover the underside of the centre plane with 1/32 wood before the nacelles are glued in place. (Drawings show all details of nacelle construction.) Cut away the underside of centre section cover-ing to take the nacelles and then fit the top rear portion of the nacelle keel. The top rear nacelle covering is now glued in position (drawings give all details.)
The wings, tailplane and rudder need no explanation here as the construction is quite straightforward. Plans give all information needed.
The undercarriage is built up as shown on the drawings.
The observation hatch is moulded from celluloid, a 'tricky business,' but it can be done (see photographs). The two formers (inside and outside) are made from wood. Insert celluloid between formers (after putting into boiling water) and push the outer former up into the inner one. Several 'boiling water' insertions may be required before the hatch emerges to your satisfaction - that was my experience, anyway!
Tissue covering: this is applied over the entire framework (including fuselage) and two thin coats of clear dope and one of banana oil are applied. Take care to avoid wrinkles when covering.
Flying: Little can be said about flying, but use three loops of 3/16 x 1/30 in brown rubber, well lubricated, and start with 100 turns on each motor (when gliding tests have been successfully concluded). As stated at the beginning of this article, the Beaufighter opens up new and very interesting fields and I shall be pleased to hear (through the Editor) of any interesting times, etc. This applies also to any difficulties encountered in the building. Before I leave you I should mention that the original model is painted 'night flying black,' but it may also be camouflaged for 'daylight' operations."

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 (oz11936) 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_Beaufighter
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.

User commentsCuriously there's no drawing to show the layout of the centre-section of the wing. At first I thought there was a page missing. But this is all of it.

Probably it's not shown because not necessary, considering it is built by notching all the parts together in a unique position and not on the plan, like the outer wing panels. The central wing sketch is enough.

* 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.
