About this Plan

Jodel D-150 Mascaret. Peanut scale free flight rubber model.

Quote: "This little model was designed as a simple scale airplane suitable for flying indoors or out, in a field, or from the street corner. It can be a little disappointing for a designer sometimes and this Jodel turned out to fly far too well for the local street corner. Built according to the plans it is capable of flights of between 30 and 40 seconds indoors and outside it has done more than two minutes, and more than one builder has been worried about losing his in a thermal.

Construction of the model is about as simple as they come and still remain in the built-up category. About the only things that are different from straight forward rubber model construction are the wheel pants and the canopy which may be formed over wooden block molds with the aid of a Mattel Vacu-form toy. If you have a Vacu-form you'll know how to use it and all you'll have to do is carve balsa block molds to the shapes desired and then form the plastic to shape around them. If no Vacu-form is available you can make the pants out of balsa laminations. The canopy can be made out of two pieces without the bubbled contour on the windshield without hurting the appearance very much and without hurting the performance at all.

Use medium weight balsa for the sticks and light balsa for the sheet cutout items. The blocks at the nose can be harder and therefore heavier balsa.

I recommend the Northern Pacific products Sleek-Streak as a source of both the propeller and the wheels. They are both light and efficient. The tail wheel need not roll and thus can be simply cut out of sheet and cemented in place.

The model should be covered with your favorite colors of lightweight tissue. Superfine tissue is best. It should be shrunk with a very lightly sprayed on fog of water and when dry brush on a thin coat of clear dope (2 parts thinner to 1 part of dope). The wings and tail should have only a single coat applied whereas the fuselage may have two coats with perhaps a third coat on the balsa parts at the nose. Flying adjustments are noted on the plan...."

    ScaleType: This (oz1471) 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
    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.
