About this Plan

Boeing Bomber. Scale model twin-engined bomber, for rubber power. Uses a belt and pulley arrangement (with rubber bands) to drive the twin props.

Quote: "Building the Boeing Bomber. How You Can Construct a Model of the Fastest and Most Formidable Bomber Ever Produced. By Howard McEntee.

MANY of my readers may have heard of the sensational bombing plane recently produced by the Boeing Airplane Company. Its remarkable speed of 2ou miles per hour and ability to carry heavy loads makes it a formidable weapon in time of war and a forceful argument for the preservation of peace. It is therefore probable that up to date model fans will consider it an essential addition to their fleet of models. Inspired by this realization, I have collected together my thoughts on this particular subject from which the following instructions and plans have sprouted.

This remarkable ship is an outgrowth of the well known Boeing Monomail plane which has given amazing results on the established Western mail lines. The bomber is rather a large ship with a wing spread of almost 72 feet and an overall length of about 52 feet. The ship is powered by two Pratt el Whitney Hornets geared down and set in the wings. On viewing the ship one is greatly impressed by the beautiful streamlining which has been achieved, especially when the ship is in flight with the landing gear folded, When this is folded only the lower part of the wheels are visible and the reduced drag is a great factor in the extremely high speed development. Think of it! A large, heavy bomber with a speed which only the most modern pursuit planes can equal!

In our model we have endeavored to retain all the features of the big ship except the folding feature for the landing gear. This, of course, is of no use for our model, and indeed it is a danger, for you can imagine the appearance of the propellers after a landing with the wheels folded.

However, an idea occurs to the writer which some of you experts can apply with a little ingenuity. Make the wheels fold up just as in the real ship, having a spring arrangement with a catch, which will hold the wheels folded, but when the catch is tripped the spring will snap them to the open position. Then have some sort of arrangement so that when tension of the motor decreases by unwinding, the catch mentioned above will be pulled. Now you can wind the motor, fold and catch the wheels and launch the model by hand. When the motor unwinds, the wheels will drop open and she is all ready to make a perfect landing. You can picture how this would look in flight. It is worth while trying, at least.

The motors are run by a pulley arrangement from the central motor, rubber bands being used to transmit the power. This is not a perfect arrangement by any means, but it is fairly reliable and above all, light in weight.

Now a word of warning. This method of transmission is, in a way, experimental, and the model is rather a difficult piece of work, so only the more experienced builders can be absolutely sure of results, because quite a bit of experimenting may be necessary to get the transmission working. Also owing to the rather short length of rubber possible., there can be no great duration in flight. However, even without flying, the model is a beauty for exhibition purposes as it is very accurately scaled and can be colored just as the real thing. So don't expect too much in the way of flying, but as for appearances, the model speaks for itself.

Fuselage: The fuselage is built up from two sides as is usual. The sides are built on a board to insure both being alike, the first one being cut off when dry and the second built on the same pattern... "

    ScaleType: This (oz14948) 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.

If memory serves, this would be the Boeing B 9 which was nicknamed 'the Flying Pencil' (way before the Dornier 17 was even a sketch on a designers notepad)

* 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.
