About this Plan

Khamseen. 40in span international A1 class glider, from Aeromodeller November 1955.

Quote: "Follow the A/1 leaders with this high performance contest design. Khamseen, by Derek Illsley.

THE ENTHUSIASM with which the model clubs have received the A/1 glider class, after mention in our June issue and subsequent publication of the 'Golden Wings' in July, has made it evident that this size of model is becoming very popular. In the main, the class has been adopted for local events, and for the encouragement of novices. The model is of handy size for transport, can be built for only a few shillings expenditure on wood, tissue, cement and dope, and is most rewarding with a good flight average of up to 1 min 45 secs duration.

Our own Golden Wings contest (see pages 590/591) has already introduced more than a thousand young enthusiasts to the delights of flying one of these easy-to-build small gliders, and now we introduce a somewhat contrasting design as its stable companion.

A stick type fuselage, pylon mounted, almost flat wing, large endplates and undercambered tailplane, will immediately label the Khamsecn as a strictly 'performance' design. Yet it is still simple enough for any beginner to tackle, providing patience is exercised when covering the undercambered surfaces - the only item likely to offer any difficulty.

Corporal Illsley has been stationed in Germany with the army and had the good fortune to be able to fly on Essen-Mulheim airfield each weekend. The local lads there have been flying A/1's for some years, so it was only natural that Cpl. Insley should try the class for himself. Choosing the name of a warm wind of the Middle East for his effort, Khamseen was soon created, and the first two models disappeared with uncomfortable rapidity when launches were made without lighting the dethermaliser fuse! There's a moral there somewhere.

The third of the series includes all the detail improvements shown necessary in the first two prototypes, and is as drawn on the reduced scale plans show.

Construction should start with the pylon outline, which is from 1/8 in by 1/2 in, stripped down from hard balsa sheet. Whilst this is drying, cut out the 1/16 in sides and sundry fuselage spacers..."

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

Mary, Some pics of our Khamseen glider by Derek Illsley [main pic, 003-005]. Covering is mylar and fuselage is clear doped. We have been using a Bungee launcher consisting of 25 feet of 3/32" rubber strip and 100' of carpet thread. Kites up nicely and has a slow floating glide. Thanks for your great service!

* 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.
