About this Plan

Sunderbus. Free flight model for electric power. A semi-scale Short Sunderland seaplane model. Uses foam construction.

Quote: "John McStea's 28in span model for four Campbell CMS-1 motors with an AUW of 100 grams. Eric Marsden reports:

Those of use who served or worked on aircraft during the unpleasantness of 1945 have particular kits of which we have fond memories - as well as ones we disliked. John McStea has a special regard for the Short Sunderland four-engined flying boat, since he's one of we happy few who have been out on the wing in flight and is still here! (He also likes Consolidated Liberators and Handley Page Halifaxes, though he hasn't been for a walk outside on them.)

The advent of blue foam construction technique, combined with Glen Campbell's tiny electric motors led him to create this 'Sunderbus' in his own inimitable fashion. Having spent many years us a Cheropodist, John is a craftsman who can create desired shapes with little need for drawings - see his Petrel which was created from the most unlikely scrawls on bits of paper and which he probably built quicker than I was able to make a working drawing which we lesser mortals could use easily.

This Sunderland, John cheerfully explains, is a sort of caricature, a cartoon, and one has to imagine that he spent some time with that little book of Wren cartoons, Oddentifications, published by 'The Aeroplane', price 2/-, rather a long time ago.

Hull. Since the model merely resembles the photocopies of enlargd portions of a black recognition silhouette, none of which agree in size, the finished drawings have been taken from the one piece model with John's verbals as an extra source of confusion! Since the Brits are a nation of sculptors, as well as of poets - we once carved up half the globe, didn't we - carving a block of blue foam to Make the fuselage is no problem. Tack glue two slabs of blue foam together for the fuselage..."

    ScaleType: This (oz9470) 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.

I hope that a kind soul can provide the build article on this one. It was published in the Feb 1998 issue of Aviation Modeller International. The plan leaves open questions on such things as battery access for charging and replacement - or is that the dotted rectangle on the side view? Is there a timer? And I cannot find a reference anywhere on the Campell CMS-1 motor. Thanks!

Your wish is our command, Chris ;) I've said it before but I shall say it again: RFJ is a marvel. Many thanks!

That's just fantastic! Thanks to Outerzone and RFJ for finding and publishing the article. So the 'Campell' motors on the plan are a typo!! No wonder I couldn't find them.

* 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.
