Quote: "Everyone likes biplanes - here's a Peanut version of a WWI favorite. BY JOHN BERRYMAN
The prototype 1-1/2 Strutter flew in December 1915, and the first production versions entered service in early 1916. Well liked by their crews and reliable by the standards of the day, the Sopwith soldiered on in various capacities (two-seat fighter, observation aircraft, light bomber, etc) until the end of the war. It was probably one of the first aircraft to feature 'dive brakes,' indicated by the dashed square panels at the roots of the lower wing. Later versions of the fighter were powered by a 130-hp Clerget rotary engine, and the ship could top 100 mph - fairly sprightly performance for a two-seater.
Sopwith's 1-1/2 Strutter (so called because of the cabane struts that reach out to mid-span on the upper wing) presents several features of interest to the Peanuteer. Unlike most WWI rotary-engined ships, the Sopwith actually has a bit of a nose moment. In addition, the tail surfaces are boxy enough to withstand some judicious enlarging via the office copier without appearing to be excessively non-scale (the surfaces shown on the plans are about 120 percent of scale).
Better still, the fuselage is also boxy enough to permit fairly light building techniques to be used - always a consideration when inherently clunky biplane subjects are considered. And finally, a substantial number of 1-1/2 Strutters (including my version) seem to have been built as unarmed aircraft. Avoiding the necessity of building itsy-bitsy Vickers and Lewis guns and associated Scarff rings and the like, reduces complexity and saves weight.
CONSTRUCTION: Wing: Not much really new here. Note that the dashed structural lines refer to differences between the upper and lower wing, and that the mounts for the jury struts are required only on the upper wing. Otherwise, the wings are identical. If you like an additional bit of insurance, you can certainly increase the dihedral from 3/8 to 1/2 in per panel..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

ScaleType: This (oz4142) 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_1½_Strutter
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.
