About this Plan

Heath Parasol. Radio control scale model.

Quote: "Most famous sport plane of its day, this open cockpit ship makes good scale RC or, with .075's, an unusual free flight subject. Sturdy as well. Heath Parasol, by Ed Yulke.

The Heath Parasol RC model shown here represents the realization of a long dream for the writer - the first 'real' flying scale model in 27 years of modeling. Rubber flying scale meant either thin, analine dye dope for a finish, most details left off, or too heavy a model to fly properly. Half-A flying scale still left too much to be desired: the writer has a heavy hand with a paint brush!

The Heath shown here, with four coats of fuelproof colored dope and all details, including faired music wire struts, weighs just 40 oz. With an .099 engine this is just 400 oz per cu in power loading and the 17 oz wing loading means she has enough 'solidity' in the air to make a practical ship for a bit of breeze: she won't blow away.

The Heath has a smooth turn because of the long wing, good recovery stability stemming from low CG, yet good maneuverability through a generously sized rudder - in this case, the scale rudder! The Heath will turn in a mean precision pattern on its rudder-only control and is able to do a few of the aerobatics.

We refuse to state that the construction is simple. No RC model is simple to build, even from a die-cut kit. Constructuion is conventional. with a few more parts to make, like struts, windshield and numerals for authenticity...."

    ScaleType: This (oz4955) 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/Heath_Parasol
    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.
