DH.94 Moth Minor (oz10377)
About this Plan
DH.94 Moth Minor. Sport scale model for 20 size engines and 3 or 4 function RC. From Radio Control Scale Aircraft, February/ March 1996.
Quote: "Quick to build, Pull-Out plan feature model of one of Geoffrey de Havilland's Minor Classics. Suitable for 4 function R?C and 0.20 - 0.30 power. De Havilland D.H.94 Moth Minor, by Mike Reynolds.
As early as 1929 the de Havilland company realised that there was a large potential market at the lower end of the flying scene which could bring the reality of practical flying to an even wider public than the existing 'Moth' aircraft or the proposed type 82 (to become the renowned Tiger Moth) would fulfil. Therefore, a new, inexpensive and simple design was initiated which emerged as the DH81 Swallow Moth, a two seater, open cockpit, all-wood cantilever monoplane with low wings thus dispensing with the high costs associated with complex rigging of biplane types. However the success of the existing Moth programs demanded total commitment of all the available production resources requiring the new project to be temporarily shelved.
Five years later the design was resurrected and moved to a dedicated production facility where in revised form it was to be built as the Type 94 Moth Minor. Power was by 90 BHP Gypsy Major engine and the airframe construction was based on the well proven spruce and ply methods.
This attractive little monoplane has not been too frequently modelled although there have been several classics built notably that of the late Terry Melleney which Terry campaigned for several seasons and with honour at three World Championships.
This little model is no World Championships contender: more a simple, low cost and compact flyer which built lightly with careful choice of materials will perform in a most satisfying manner. There are variations possible on the simple open 'two-holer' white and blue finished concept which most people associate with the Minor in the form of a coupe version or a camouflage scheme. We hasten to point out that the coupe version has not been built but should not exhibit any significant differences to the open version in flying performance.
Wing construction. The wings are of classic D-box construction which happily reproduces the ply and fabric construction of the original. They do not fold, although apart from added weight of suitable hinges and fixtures, there is no reason why they should not, it just seems a little bit over the top to try anything so complex on such a simple little model. The centre section is flat and includes a laminated Liteply undercarriage spar. Chose either hard 3 mm balsa or Liteply for the CS ribs, they have to support the U/C.
Assemble the ribs, spars, false leading edge and U/C spar over the plan angling the outer ribs to the dihedral template and whilst it is still pinned down, cut away the outer ribs to fit the dihedral braces. Glue these into place and then sheet the top surface with soft 1.5 mm sheet. This can be well sanded down after assembly is complete..."

ScaleType: This (oz10377) 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 https://en.wikipedia.org/wiki/De_Havilland_Moth_Minor
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.
