About this Plan

Druine Turbulent. Free flight scale model by Doug McHard, 21 inch span for .15cc Allbon Bambi power.

Quote: "The Royal Turbulent. Doug McHard was commissioned to build a solid scale model of HRH The Duke of Edinburgh's Druine Turbulent King's Cup Air Race entry. We are pleased to feature not only plans of this original model, but also Doug's FULL SIZE working drawings, and photo illustrated instructions, for building a Bambi powered free-flight replica of the same machine.

THIS year, HRH The Duke of Edinburgh entered an aircraft in the King's Cup air race for the first time. The type chosen was the little Druine Turbulent, a French design built in Britain by Rollasons' of Croydon. The Duke of Edinburgh's Equerry, Squardron Leader S de Milt Severne, AFC, piloted the machine and placed very well in the qualifying rounds, only to be defeated by high winds, which favoured the more highly powered aircraft, during the actual race.

Before the news of the Royal entry was made public I was commissioned to produce a 1/36th scale replica of the Turbulent which was presented to His Royal Highness, and from which the racing colour scheme was selected. 1/48th scale plans and photographs of this model appear on page 320.

Eagle eyed readers will spot one or two differences between the model's original decoration and the colour scheme eventually employed. The most obvious of these is the raring number disc which was subsequently enlarged.

After producing this little solid job, I thought how effective a F/F flying model would look and shortly afterwards built one around a DC Bambi. Full size plans are presented overleaf, and, together with the accompanying constructional photographs, should enable any modeller of modest experience to produce his own King's Cup entry in miniature.

Construction. Build the fuselage first and start by cutting nut all the formers, A in. square crosspieces. both fuselage sides and engine bearers, firom the material indicated on the plan. Before assembly is started bend the undercarriage from 18 SWG piano wire and sandwich it, with plenty of cement, between formers 4 and 6 using former sections 5 as locating and packing pieces. Allow to dry.

Cut the hardwood engine bearers accurately to the length indicated on the side view and note which is top and which is bottom. Drill the 1/16 in holes for the 8-BA engine mounting halts and elongate them forward wills a round 'Abrafile' to enable thrustline adjustments to be carried out later..."

    ScaleType: This (oz910) 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/Druine_Turbulent
    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.
