About this Plan

DH.89a Dragon Rapide. Scale twin biplane. Cox .049 power shown. Aeromodeller Sep 1968.

Quote: "Veteran modeller HJ Towner's control line replica: 7/8in equals 1ft scale for two .8 - .16cc engines diesel or glowplug.

THE DRAGON RAPIDE holds more affection among British pilots and many air travellers than any other similar type. Now, alas, she is of a dying breed, irreplaceable due to present day requirements which demand more power, more weight in consequence, and far less sense of actual flying.

There are many D.H. 89s still with us - in all quarters of the world, earning their keep in varied ways. We thought it ought to be preserved as a model subject - and who better to do so than that doyen of Scale modelling in Great Britain - Harold Towner? So here is his version, for control-line over to Harold: In building a fully detailed model of this nature it is necessary to complete the interior at a very early stage.

Commence by laying down the top and bottom keels and joining together fore and aft The respective formers then can be eased into their slots. It may be necessary to gently separate the top and bottom keels one end to

On the original model, Evostik Resin W was used as an adhesive throughout.

Window frames are now added out of scrap to line up with the inside of formers F3, F4, F5, F6, F7 and F8. Add the floor (1/32 balsa) with grain across the fuselage, resting on the lower keel. Use coloured art paper for the floor, sides and ceiling, covering the window frames to the outside of the formers using a polycell type of adhesive that does not stain.

The seats can now be made up of suitable material and glued firmly into position. Window glazing can now be done using acetate sheet about 1/32 in thick pressing in to the window openings achieve this.

The main longerons should now be added making sure that all is square. In order to bend the main longerons at the front end, gently rubbing the inside surface up and down on a not-too-hot electric soldering iron should achieve this. Make sure that both the right and left longerons are the same curve. This of course should be done and longerons matched before assembly.

Cross member F4a and the main wing beam F5a should be fitted and also the door frame. Fit the hardwood cross member, together with bell-crank and lower wing tongue boxes, bound with thread and cement before fitting into place... "

    ScaleType: This (oz1691) 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/De_Havilland_Dragon_Rapide
    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.

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.
