About this Plan

Vickers Wellesley. Control line scale 1930s British single-engine bomber by Mike Hollison, Fox .15 shown.

Designed around a pair of cut-down foam-core Eldon Giant Styro-Glider wings.

Quote: "When deciding what model airplane to build, you can exercise several options. You can select the design first, then buy the materials needed, or pick a design which can be made from materials at hand. You can also look for a model guaranteed to raise the question at the flying field: What is it?

The Vickers Wellesley bomber was a result of the second approach; namely, what plane could I build around the wings of an Eldon Giant Styro-Glider. While the 'What is it?' approach was not intended, this particular model seems to raise that question whenever it appears in public!

The full-scale Vickers Wellesley was, in part, the brainchild of Dr Barnes Wallis. It utilized the geodetic method of airframe construction perfected by him. This technology was later used in the design of the famous Wellington bomber. With a wingspan of 74' 4", and powered by a 925 hp Bristol Pegasus engine, it proved ideal for the RAF Long-Range Development Unit. In 1933, the RAF entered three Wellesleys in a distance attempt for a 7162 mile journey from Great Britain to Australia. Two of them reached Darwin, Australia on November 7, having completed the distance in just over 48 hours.

Obsolete as a bomber by the beginning of the war, the Wellesley nevertheless saw active service in that very role against the Italian forces in East Africa and the Sudan, and was even credited with several "kills" against enemy aircraft.

Construction: Begin with the easiest part first - the wing. Should a Styro-Glider kit not be handy, scratch-build the wing from a piece of foam, using the standard hot-wire cutting method. Separate the two wing panels and incorporate 2" of dihedral under each tip when re-joining. The Styro-Glider wings must be shortened from their standard 44 in span to 38 in, and slots for plywood and balsa bracing spars cut in each panel. Each half should also be slotted for the spruce strengthening spars top and bottom, and at the ends for the balsa tips. The ailerons should also be cut out and ready for covering..."

Update 21/08/2021: Have rescaled this plan up to fullsize at 41 in span now, thanks to ghostler.

    ScaleType: This (oz1294) 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.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Vickers_Wellesley
    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.

Notes

* 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.

Scaling

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.
