About this Plan

Boeing XL 15. Scale model for free flight.

Quote: "UNUSUAL in outline, and outstanding as a scale model, the Boeing XL 15 is ideal for 1-2 cc diesels. Its simple structure and crash-proof wing mount enhance the unique appearance of its pod and boom layout.

Wing fixing. An explanation of the wing fixing given first may make the construction more understandable. The idea, borrowed with thanks from Evan's Jaguar Wakefield (oz584), is the use of a pair of wing pegs made from four laminations of 1mm ply, cemented together over the middle portion only. When turned sideways these pegs can be pushed through the fuselage centre section, and when turned upright are locked into position. The protruding ends are a push fit into peg boxes in the wings. These peg ends, not being cemented, are flexible in the backwards and forwards direction, but are rigid up and down, so giving a good knock-off wing mounting. Other advantages are that the pegs are easily replaceable if broken; dihedral angle is easily altered if necessary; and the interior of the fuselage can be kept clear of non-scale protuberances, which in this model would be very noticeable.

Fuselage. Laminated Formers: Because of peculiar shape and open construction of the fuselage, the assembly is based on the use of laminated formers, F1, F2, F3, F4, F5 and F6. Laminated formers are strong, rigid and make for accurate alignment in assembly, and they are definitely worth the extra trouble. Construct as follows. Strip 1/16 in sheet into 3/8 in wide strips, and cut from these the shapes shown on the plan; one set for each lamination. Pin a sheet of waxed paper on the plan, and cement the pieces forming the first layer on to this paper, when they will be held in position sufficiently well. The next layer is now cemented on top, so that the strips overlap the joints of the first layer, and so on; it is this overlap that gives the strength at the angles. When dry, the formers can be stripped from the wax paper, and chamfered where necessary..."

    ScaleType: This (oz7344) 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.
    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.
