About this Plan

Bellanca Light Tractor. Peanut scale rubber model.

Direct submission to Outerzone.

Update 8/10/2022: Added article, thanks to Pilgrim.

Quote: "Peanut Bellanca, by Don Butman. Another modeler has been caught by the Peanut Tidal Wave! The search is always on for different and unusual subjects. The Bellanca Light Tractor certainly fills the bill.

Safety, efficiency and economy par excellence! - these words, plus 'Simplicity and Grace,' appeared as advertising descriptions of the Bellanca CE 2-Place Biplane in Aviation Magazine, dated May 15 and June 1, 1919. The model shown on the plans is of the single-place version powered by a 35-hp Anzani ('Dependable Wartime-Tested') engine. It utilized wing warping and had a balanced rudder.

Other interesting facts include a 11.5:1 glide ratio, which meant that if you could get to 4600 ft altitude (stated time - 14 minutes, with 25 minutes to 15,000 ft), you could glide anywhere 'within a diameter of 24 miles'. Further, only 6 hp was required for horizontal fright, er flight! The top speed was 86 mph with a landing speed of 32 mph.

The model is typical 'Sticks ani Tissue' construction, with the fuselage side shown cross-hatched. The spar-less wings are highly undercambered (think my pencil slipped?) which makes covering the panel bottoms a bit tedious. The tissue must be stuck (glued, doped, or ?) to each rib bottom, and I found that a drop or two of water rubbed into the tissue along with the dope seemed to do the trick.

The use of 1/32 and 1/64 plywood (struts, fairings, etc.) in place of balsa eases the pain of cutting small parts. Actually, the 1/64 plywood may be easily and neatly cut with a pair of fairly sharp scissors.

The two profile pilots shown on the plan were installed in my model and really do add a touch of realism! There is just nothing nicer (well, almost nothing!) than a peanut scale model toolin' through the air complete with Les Pilotes! ('Les Pilotes' are the artistical creations of the author's son, Darryl - WCN)

The model flew with no adjustments, which rather astounded me, since both wings warped a bit! But fly it did, until the 'airplane-eating-tree' in my front yard caught it!

Oh yes, one last tid-bit of information from the past - Mr Joseph Bellanca's early efforts were financed by the Maryland Pressed Steel Company. He was the Chief Engineer of the Aircraft Department, and Mr Harry E Tudor was the New York Sales Manager.

The information concerning this Bellanca aircraft was supplied by Mr DD Hatfield, Aviation Historian, of the Aviation History Library at Northrop Institute of Technology."

    ScaleType: This (oz3895) 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/Bellanca_CE
    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.
