Cessna C-34 (oz284)
About this Plan
Cessna C-34. From 1939 Model Airplane News.
Quote: "How You Can Build One of The Finest Scale Models Ever Flown - Sturdy and Realistic in Appearance. It Has Flown For More Than Two Minutes and Won a National Contest. Cessna C-34, by Dick Korda.
Now that the flying scale model is part of all major contests, the main question is: which one to build? The answer to this question during the Scripps-Howard National Contest in Akron last year proved to be the Cessna C-34. It took first place in the eliminations in Cleveland, with a flight of one minute, and also took first place in the finals in Akron with a flight of two minutes, five seconds. The winning flight was made in a strong breeze covering over half a mile before it disappeared behind a small woods. The points given for first place in this event were just enough to help tie as high point man and gain partial possession of the Al Williams Trophy.
Fuselage: The fuselage is built up of 3/32 square hard balsa, the two sides being laid out and joined together the same as a regular fuselage model. The cowling is built next and is covered with 1/16 medium balsa. Two tappet covers are glued on over each cylinder. The size of the cowling may be obtained from the top and side view drawings. Make the seven cylinder motor as complete as pos-sible to help gain points in contests. After the motor and cowling are finished glue them to the fuselage and add the stringers as shown. Drill a hole through the landing gear block on the bottom of the fuselage and slide the bamboo strut through, gluing it to the block and also to the cross brace in the body. Then using a plastic wood made of cement and sawdust, form a fillet where the landing gear joins the body. Airwheels are held on the axle with a drop of cement.
The wire tail wheel strut is cemented to a balsa plate which is fitted inside the last upright on the body. The body is covered with small strips of paper from the cowl to the landing gear only. From there back it may be covered with one piece of paper to each side. After spraying with water no wrinkles will appear. Next put on the side windows, using dope instead of cement to avoid wrinkling the celluloid. The windshield is not fitted on until the wing has been glued to the fuselage. All longer-ons and uprights showing through the win-dows should be covered with 3/32 strips of black paper.
Wing: Lay out the entire wing, minus the spars, and allow to dry completely. After putting in the center section spars, crack the leading edge and put blocks under the tips for dihedral. Glue in the top spars and allow to dry, then turn over and glue in the bottom spars. Sand off bumps on ribs between spars from the last spar to the leading edge as this will eliminate unsightly bumps on the wing after covering. Cover wing and spray with water. When dry give it two coats of thin clear dope. Then put on the license numbers and cement the wing in place on body. The correct place is given on the plans. Landing flaps and ailerons are indicated by 1/16 strips of black paper... "
Update 31/10/2019: Added article, thanks to RFJ.
Update 01/11/2019: Have re-scaled this plan up to correct fullsize at 36 in span, thanks to SimonBlake for pointing this out. Makes a lot more sense this way. So it's now double the size of the previous version we had (..ahem, for the last 8 years).

Previous scan version.
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 (oz284) 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/Cessna_Airmaster
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.
