About this Plan

Avro 534C Racing Baby. Peanut scale biplane model. May 1975 Aeromodeller.

Quote: "THIS RACER, built by Avro in 1921, was ill fated: it never did actually race, but crashed into the water following a power failure. Several other versions of the Baby were built, but this particular one was selected for a 'Peanut' as it had the shortest wing span of any. Its proportions are just about ideal for a rubber-powered model, with one exception - its nose is rather short, so it is really important to keep the tail light.

The model has all the standard components of an early '20s biplane. It utilises standard building techniques throughout, with the possible exception of surface outlines, if you are so inclined. Scale rib spacing is employed, but the leading edge riblets of the full-scale aircraft were omitted. Wheels manufactured by Fulton Hungerford were used, and these are truly beautiful. However, the model shown required quite a bit of nose ballast, so hardwood or plastic wheels are recommended.

The surface outlines can all be made in the fashion shown on the wing plan. Cut them out of sheet balsa to the shape shown, which will require four to five pieces for the rudder, and as many as eight or ten for the horizontal tail. The technique is familiar to anyone who has ever built a model. Or the surface outlines can all be laminated out of thin strips of model railroad basswood. This results in outlines which look much nearer true scale. Actually, the model illustrated even has the wing outline made of basswood laminations. If basswood is not available, thin balsa strips can be used for laminations, but basswood is easier to work with as it can be bent around curves formed by pins without wetting. Balsa will require soaking in water and bending around a card or balsa former to prevent cracking. This might even be almost impossible at the trailing edge of the wing tips. If you are limited to balsa, making the wing outlines as drawn is recommended..."

ScaleType:
  • Avro_Baby | help
    see Wikipedia | search Outerzone


    ScaleType: This (oz2520) 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/Avro_Baby
    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.
