Bellanca Monoplane (oz1074)
About this Plan
Bellanca Monoplane. Scale model for Cub .099 power.
Quote: "The prototype of our model dates back to 1927 when it was built and groomed for an attempt at the first non-stop trans-Atlantic hop. But fate dictated otherwise - the Bellanca plane failed to make this flight - it was beaten to the record by Charles Lindbergh.
Though it missed out on this attempt, the 'Columbia' scored on two others. Clarence Chamberlin piloted the plane across the Atlantic to Germany, carrying Charles A Levine as a passenger. This single flight established the first non-stop passenger flight across the Atlantic and the first non-stop flight from New York to Germany.
To the best of our knowledge, the Columbia was called a flying gas tank. The craft had an empty weight of 1850 lb, and took off with a stupifying total of 4,100 lb (451 gals, of gas), more than two and one half times the empty ship itself. This alone explains the need of an enormous airfoil plan, and the well known Bellanca lifting struts. To haul this mountain of fuel, a 200 hp Whirlwind J5 Wright engine was employed, spinning a Hartzel Walnut prop some 99 inches in diameter.
Our miniature is a 3/4in scale model of the original, powered by a Cub .099 or similar Class A engine. We adhered to scale as close as possible, beefing the structure at all weak points. Construction is started after scaling the plans to full size, or by having them photostatted to proper size.
Fuselage. The entire fuselage is framed from 1/8 medium grade sheet balsa. Shape the sides as shown, using 4 in wide stock. The balance of the 1/8 sheet is used for formers.
Since the fuselage is of box design, construction is narrowed to a few simple steps. Cement the formers between the fuselage sides, starting with former C and working fore and aft. Secure the 3/8 square hardwood engine-bearers in the precut openings as shown, and cement well. Cement the plywood firewall against former A. The bellcrank is mounted to a sheet of 1/8 plywood and, in turn, woodscrewed to the motor bearers. Cut the required lead-out clearance holes in the fuselage side..."
Note this is a low resolution plan.

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 (oz1074) 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 https://en.wikipedia.org/wiki/Wright-Bellanca_WB-2
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.

* 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.
