Update 25/4/2022: Added article, thanks to Pit.

Quote (google-translated from the Fench): "The Douglas Boston Havoc flying model. By Emmanuel Fillon.

See first part of the article and full-size plans in preceding MRA issue (376). In the previous issue, we reviewed the general points and you were able to study the triptych plan and inset the assembly views. The insert of this issue gives you the full scale detailed outline of all the frames and ribs of this model.

Construction: Fuselage: The fuselage as well as the central part of the wing, the jumping spindles, the fin, and the landing gear form a whole. Mounting can be done on a central core made up of two braced 5 x 10 rods, or in two right and left parts that are joined together. Note the presence of wedge heels under the engine nacelles, which allows them to be perfectly aligned on a flat site. Depending on the destination, the couples can be full or lightened following the route indicated in broken lines.

The monocoque covering must not exceed 1 mm in thickness in the rubber version and will be 3 mm in the IC engine version. The width of the rods must be appropriate according to the difficulty of recovery; it is obvious that the flat parts can be executed with slats 15 to 20 mm wide, on the other hand for the roundings of small radius, use strips of 3 x 3 or 2 x 3 and if necessary plan them in trapeze.

The engine nacelles are treated as a monocoque like the fuselage except for the annular engine cover and the rear tip which will be cut as the case may be in a block of balsa or expanded polystyrene. I would like to point out that for the heat engine Les Belles Maquettes sells a spun aluminum cover exactly adapted to the size of this model..."

    ScaleType: This (oz516) 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.

* 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.
