About this Plan

Tipsy Junior. Scale power model. Allbon Bambi shown.

Quote: "An 18-1/2 inch span free flight scale model for Bambi owners. Tipsy Junior by Walt Mooney.

The Tipsy Junior is a single place low wing design which has had considerable success as a full scale airplane. It is a simple design with much eye appeal, with its small size and harmonious surface profiles.

This free flight Bambi-powered model of the Tipsy has all the eye appeal and is still fairly simple to build and fly. It does take a little more care in trimming out for flight than say a good high wing sport model, but due to its small size and light weight, it is virtually crash proof.

Fuselage. The fuselage is made up of two sheet balsa sides, with sheet balsa formers and a plywood motor mount. It is best to cut all of these out before starting any assembly. Note that the fuselage sides must be made to the exteneded length shown to account for their curvature in the plan view. Then assemble the fuselage starting with a 3/32 square tail post at the rear. Install the formers working forward..."

Update 08/05/12: Have resized this plan, it seems the correct span is 18.5in, not 21in. Thanks also to MikeNelson for the article page scan.

ScaleType:
  • Avions_Fairey_Junior | help
    see Wikipedia | search Outerzone


    ScaleType: This (oz1686) 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/Avions_Fairey_Junior
    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.
