About this Plan

Sopwith Dolphin. Free flight rubber scale model. Scale is 1/48.

Quote: "Pint-sized flying model of World War I fighter incorporates the same wing arrangement as our modern Beechcraft. Sopwith Dolphin, by Joseph Wherry.

EARLY in 1918, British squadrons at the front began to receive an entirely new type of fighter, the Sopwitb 5F.1 Dolphin. As a matter of fact, research discloses that Dolphins were first received by No.87 Squadron in December of 1917. With its inverted staggered wings and bulldog nose, span of about 32 feet 6 inches, and four machine guns, it was indeed something out of the ordinary.

The 200-hp Hispano-Suiza engine gave it a top speed of around 122 mph at 10,000 feet; this height was reached in 12 minutes. Maneuverability was excellent and the open space betwen the top planes gave the pilot a fine range of visibility. The two Vickers guns were mounted conventionally on the cowl; the Lewis guns were mounted on the forward spreader between the top planes. These two additional guns fired over the propeller and could be elevated at will by the pilot who had to be a dandy to fly and fire these guns at the same time. No.87 Squadron remounted the Lewis guns outside the propeller disk on the lower wings where they were fired by means of Bowden controls.

This seldom modelled First War fighter was actually built in fairly large numbers: over fifteen hundred Dolphins were completed of which about 400 were consigned to the Western Front. Nos. 19, 23, 79, and 87 Squadrons were entirely equipped with this ship. No.85 Squadron received Dblphins to augment their SE5As. Had the war continued longer, Dolphins and Sopwith's 7F-A Snipe would have eventually equipped most of the British fighter units.

Our model of the Dolphin spans just over 8 inches, is constructed mainly of 1/32 inch sheet balsa of medium grade, and will make several turns around your parlor when fitted with the flying propeller before color doping. Two coats of thin color dope will enhance the beauty of your model, but will make it a bit heavy for powered flight. However, a scale propeller may then be fitted and you will still get some snappy flights outside on calm days when you throw it in glider fashion. A satin smooth finish is never given these little jobs by the author; to do so would be to render it incapable of flight because of weight. Enough of this; you'll like these parlor flying scales that look like solids. Let's get started.

Fuselage: Utilizing the template, cut two sides from 1/32 inch flat stock that has been first lightly sanded. Study the assembly views and mark the places where the 1/16 inch crosspieces and No. 4 bulkhead fit. Join the sides together at the rear and install the cross-pieces. Next install No. 4 bulkhead. Rubber bands are used to hold sides together until dry..."

    ScaleType: This (oz3537) 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/Sopwith_Dolphin
    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.

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.
