About this Plan

Mooney Mk 21. Radio control scale model. For .60 power.

Quote: "Designed as a functional stunt model, our semi-;scale R/C continues the trend towards realism. It has that 'Looks-Like' appeal. Span is 70 in. Mooney Mark 21, by Gerald Nelson.

MY Mooney is a semi-scale stunt model which resembles a 1963 Mooney Mark 21. It is intended to be a stunt job first, a scale job second.

No major breakthrough in the state of the art has been made with this design. It is intended to be an interesting looking, functional stunt model using basic con-struction techniques and materials. Regarding the semi-scale aspect of this ship, several excellent articles have been writ-ten lately noting the trend towards real-ism in stunt models. This trend is gaining momentum and I am pleased to see this happen. One of the purposes of Mooney design is to encourage and promote this trend.

The original, classic stunt job theme - Kwik Fli (oz6526), Taurus (oz612), etc - will be with us for sone time. This type of model flies excellently, is easy to build, and has an excellent contest record. However, there are flyers who are looking for something different. They want a design that they can identify with a full-scale aircraft.

R/C models are tending to become miniature aircraft, and not toys. To help the image of R/C model airplane flying as a sport, realistic-looking designs are needed instead of our standard 'toy air-planes.' Take a design like the Mooney to a flying session and watch the specta-tors group around the ship. They may or may not recognize it as a Mooney light aircraft, but they will recognize the fact that it looks like a miniature light air-craft. When you fly the ship all eyes are watching its progress in the air. After the first flight, the flyers of the unrealistic ships can be seen comparing their stereo-typed jobs to the Mooney. They usually go home saying something to the effect - Maybe I should build something like that Mooney.

You are not at a competitive disadvantage with this design. It will do all the new 1968 AMA maneuvers, plus a few other maneuvers that might come into effect in 1969. The list of 1968 maneuvers will probably grow. The Mooney has the requirements for the future maneuvers.

The only disadvantage of the Mooney's design is a little extra work in building the fuselage. There are a few extra deals, like the hatch, rounded fuselage top, wheel-well doors, and a scale-like paint job. When you think about it, the extra
work isn't very much. The almost scale fuselage width will allow any kind of radio to be installed with room left over. There is also ample room for a retractable landing gear system, if you want one.

The wing span is somewhat large by current standards (70 in). It is highly tapered, which brings the wing area down to normal areas. The airfoil is a relatively thin, symmetrical section. This section is advantageous for the flying performance we now require. The ship flies at a good speed, and can slide through the maneu-vers instead of being pulled through them by brute force. The section also provides an excellent glide path by forcing the model to fly slightly nose high..."

    ScaleType: This (oz7729) 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/Mooney_M20
    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.
