About this Plan

Thomas Morse S4C Scout. Free flight scale model WWI biplane trainer. Wingspan 35in.

Quote: "A 35 inch span, 1/9th scale replica of the early American biplane using .8 to 1 cc engines. Thomas-Morse S4C Scout, by JG Watkins.

THE FIRST AIRCRAFT designed specifically for fighter training, the Thomas Morse Scout has a particularly 'British' look to it - not surprisingly, as that company's chief designer, B Douglas Thomas (although no relation) was an Englishman who had previously been employed by both Vickers and Sopwith.

Fortunately, this model does not possess all the flying characteristics of the original - many of its peculiarities being caused by the rotary engine - and is a very stable performer. In fact, the fine flying performance prevented us from finding the designer for quite some time when we witnessed its flights at the 1970 Old Warden rally - he was flying it non-stop and was only to be seen constantly trotting down wind retrieving his creation! So successful a performer is it that we are informed that with the exception of a competing flight at the Middle Wallop rally (isn't that always the way?) the model has give over three hours 'air time' without any 'failures'. The quickly detachable wings allow easy transporta-tion, while also affording crash protection if required!

Further scale details may be gleaned from the Aerornodeller Plans Service's pack no AJ.2887, price 20p. This comprises an article reprint and drawings to 1/72nd and 1/48th scales.

The fuselage is begun by cutting out all the formers, then bending the undercarriage and cabane struts to size. Sew and epoxy these to F1 and F2. Build two basic fuselage sides from 1/4 in x 1/8 in medium hard balsa, and 1/8 in balsa wing mount as shown. Glue formers F1, 2 and 3 in place, checking that they are square.

When dry, join the fuselage sides at the rear, followed by the 1/4 in x 1/8 in cross pieces, making sure that the fuselage is not warped. Cement the bearers in place using a PVA or epoxy adhesive, then glue the remaining formers in position - leaving F6 to last. Rear fuselage stringers and top deck sheeting may now be added.

Build the cowling ring from cross laminated 1/8 in hard sheet, and cover with 1/8 in medium hard sheet to F1. Add all under-carriage and cabane fairings then sand to a stream-lined section..."

    ScaleType: This (oz4088) 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.
