Bell P-39 Airacobra (oz211)
About this Plan
Bell P-39 Airacobra. Control line stunt by Walton Pyron.
Quote: "Acrobatic Airacobra, designed, drawn and described by Walt Pyron.
During the past few years changes in the AMA stunt pattern have made an exceptionally good flying airplane an absolute must. Although this Airacobra model possesses an amazing resemblance to its real counterpart, it was actually designed with good flying characteristics in mind. The general configuration of the real Bell P-39 offers many very desirable features for a high performance stunt model.
The tricycle landing gears make take offs and landings practically fool proof. By side-mounting the motor, semi-cowled fashion, a cool steady engine run was assured, plus easy accessibility. (Needless to say, a fully cowled engine can bring about a serious over-heating problem on those hot summer days.) I chose the British version of the Airacobra because of its beautiful multi-colored paint scheme.
As for flying, the Airacobra will fly as well as any stunt model out today, It is smooth and stable, and will turn on a dime. Now let's get down to the construction details.
Start by cutting out the 1/8in sheet balsa fuselage sides and doublers; cut both sides full length. Cut out the fuselage formers and secure the 1/8in steel landing gear wire to F-1 with 'J' bolts. After the doublers have been glued to the sides and they have thoroughly dried, glue the rear of the sides together with x 1/8 x 1/4 spacer between them. Glue the formers in place, working from the back of the fuselage to the front. Set this aside to dry, and begin wing construction..."
Quote: "also attached is a slightly different version of Walt Pyron's Acrobatic Airacobra which is already posted. This much cleaner plan is from American Modeler magazine issue 07-59."
Update 29/12/2016: Added a supplement alternate version of the same plan, by Uncle Willie (shows full wing layout), thanks to ffrankie.

ScaleType: This (oz211) 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/Bell_P-39_Airacobra
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.
