About this Plan

Heath Midwing (Heath Parasol). The plan shows details for both designs. Scale free flight / CL 1/2A gas model. From Air Trails, December 1950.

Quote: "Shades of the Thirties! Look what's here: Ed Heath's famous Parasol and the not-so-well-known Midwing job.

Take your choice - both the Parasol and Midwing are good performers. In the search for outstanding scale models, one is apt to overlook many old-time designs which are excellent for both U-control and free flight use.

In its day (the early Thirties) the Heath Parasol was the most famous single-seat lightplane made. Available in finished or kit form, the Parasol saw extensive use, as variations fitted with skis, wheels, or floats enabled it to be flown just about anywhere. A later version, the Midwing, became very popular due to its compact size and greater speed. Still using the same basic framework, the Parasol was modified again, this time emerging as a biplane glider, the first glider to perform the loop. Such was the genius and diversity of Ed Heath, a true pioneer of the lightplane.

The Parasol makes a fine free flight model, and the Mid-wing seems to be the answer to a stunt man's dreams. The U-controlled Midwing can be powered with any engine within .045 to .099 cubic inches displacement, and with a little 'beefing-up', a .19 or .23 can be accommodated.

In the latter case, however, it should be noted that the nose is quite small in size and a .19 or .23 may be too tight a squeeze - a scale model looks so much better when the engine is partly or fully cowled in. Due to the fairly long nose moment, it will be necessary to shift thw ing forward from the scale position when using a .19 or .23. As a parasol free-flighter, any engine of .020 to .070 cubic inches will do nicely.

Before construction is started, it should be rememebred that flying characteristics will be affected by the grade of balsa used..."

    ScaleType: This (oz1737) 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/Church_Midwing_JC-1
    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.
