About this Plan

Consolidated XBY-1. Scale rubber model, printed as a scaled-down 13 in peanut size model. Scaled up as dimensioned, it is a jumbo scale model at 27in span.

Quote: "CONSOLIDATED XBY-1. An Experimental Navy Bomber. By Mark Fineman. This Vega lookalike is the military version of the Consolidated Fleetster. You can build it from fullsize plans, available through our plan service, or turn the page and build a peanut version.

In answer to everybody's first question: no, this is not a navalized version of the Lockheed Vega! The resemblance between the Lockheed and Consolidated products is striking to be sure. And the Consolidated Fleetster (the progenitor of the XBY-1) was a contemporary of the much more successful Lockheed ship. The Fleetster, like the Vega, was intended to be a single-engine commercial aircraft, but for reasons about which one can only speculate, the Fleetster never equalled its Burbank contemporary.

The Fleetster was actually produced in two versions, a high-wing cabin job (the Vega look-alike) and a parasol wing version with the pilot situated aft of the wing. The Fleetsters, incidentally, used an all-metal monocoque fuselage, unlike the all wood Vegas. Only about two dozen Fleetsters of all types were ever built.

The depression economy provided lithe market for the Fieetster, a fact that was not helped by Reuben Fleet's own indifference to the big transport, even though it was named in his honor! In an effort to breathe new life into the project, Consolidated engineers reconfigured the Fleetster into a military aircraft, resulting in the XBY-1, a handsome, monoplane Navy bomber in an era when the Navy was hopelessly smitten with biplanes. Besides being an all-metal monoplane, the XBY-1 had an internal bomb bay, a flush-fitting dorsal gunner's hatch, and beautifully panted fixed landing gear. The XBY-1 was intended for carrier work, being equipped as it was with a tail wheel and retractable arresting hook.

With a fixed span of 45 feet, the big ship might have been quite a job to handle within the confines of a hangar deck, but the XBY-1 was scratched by the Navy before she ever saw the deck of an aircraft carrier. This innovative bomber was believed to have lived out her remaining years as a hulk in a mechanics' training school.

As a subject for a scale model, the XBY-1 is all but perfect. It has good moments and areas coupled with the usual stability of a high-wing cabin job. There are just enough details to make the project interesting, but not enough to cause frustration. The entire model, except for a slightly enlarged stabilizer, was built It 1/20 scale in honor of my Czech model building friends, who design all of their scale models to that criterion.

CONSTRUCTION: Construction tips: most of the major sheet structures (wing ribs, fuselage formers, etc) are cut from 1/16 sheet. It is recommended that you take the extra time to cut the fuselage formers from 1/16 sheet made up from cross-laminated sheets of 1/32 balsa. This will add a great deal of strength to the finished model with a negligible weight penalty. Tail out are also laminated from strips of 1/32 sheet softened in hot water and household ammonia, cemented around a cardboard form with diluted white glue. In much the same manner, the upper and lower fuselage keels are laminated from soaked 1/16 square stringers

Wing: Construction is quite conventional. Note that the wing tip is raised to meet the main spar, which is a practice that adds some aerodynamic stability, much like tip washout, and simplifies covering. I added a thin strip of carbon fiber tape to the lower surface of the mafri spar for added strength, but this step is entirely optional..."

    ScaleType: This (oz5389) 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/Consolidated_Fleetster
    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.
