I drew these plans in the late summer of 1957 and had them published in Aeromodeller in the spring of 1958. I remember being very pleased to see it in print and being paid the sum of 7 pounds, 7 shillings for it. I still have the magazine and the complimentary plan that Aeromodeller sent me. The model was as accurate as I could make it from the information I got from Slingsby. It flew - in a straight line down the gentle slope of one of my father's fields and did survive a number of flights. In later years I did think of enlarging the drawing for r/c but there was always some other project that came along and demanded attention. I was pleased to see that my work of all these years ago was still available and that your web site still promotes old fashion modelling traditions in the present times of ARTF models.

I built a model of this from M.A.P. plans in 1964 and remember well the first flight. After adding four (imperial) pennies as noseweight for balance, a beautiful straight and very gentle descent of something like 100 feet was achieved even though launched only from shoulder height. I think this aircraft has very elegant lines.

For me, this plan is a wonderful blast from the past. In 1956, when I was a cadet NCO in the Herbert Strutt School CCF, I got my A & B gliding certificates in one of these aircraft, registered XE799. The following year I built a 1/8 scale model of XE799, but I never actually flew it. My design had some structural issues and the model came out far too heavy as well. With that combination of problems it was safest to keep it as a display model. What eventually became of it I do not remember. In recent years there has been a lot of interest in XE799, which I understand is now owned by the museum at Lasham Gliding Centre, where it is being restored. It is said to have been flown at one time by none other than Johnnie Johnson while he was station commander at RAF Cottesmore. I only learned of that connection in the last few days. I am quite amazed to think that I once flew an aircraft associated with a famous WW2 ace. Somewhere among my vast collection of old photos I may still have one I took of XE799 using my Dad's Ensign box camera in 1956. If I manage to find it I will scan it and let you have a copy.

I think the museum Tony is referring to is the Gliding Heritage Centre at Lasham Airfield.

* 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.
