About this Plan

Chief. Radio control mod to the clasic FF glider model.

The Keil Kraft Chief (oz9) first appeared in 1950. This here this is a later article in FM 1960, detailing how the design can be adapted for single channel RC. Includes full drawings showing both the FF and RC model.

Quote: "The 'Chief' was designed some years back as a Nordic type towline to meet the A/2 specifications then in existence. The basic design did amazingly well in competition, and took many firsts in England and on the continent.

It is an ideal design for radio controlled soaring as the fuselage is roomy enough for most of the lightweight RC equipment available today. Batteries and radio replace the ballast, so the increase in weight is not a great deal. Proportions are well suited to RC, and the design is stable and easy to handle on the towline. It is an ideal project for the newcomer to RC flying, as a soarer is much more forgiving than a hot powered job.

As an A/2 without the RC, it will give you a great deal of experience in flying this exacting event. The design features an auto-rudder, which allows the model to tow straight on the line, and then wheel into turning flight as soon as released. Plug-in type wing panels are used which knock free on impact. A one-piece wing may be used, if desired. Dethermalizer is pop-up stab type..."

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

Steve, My Dad and I built one of these when I was nine. Anything was an improvement over our previous Soarer Major and I have happy memories of my father running across Minchinhampton Common with our towline holder made from a garden cane and a 16 mm film spool. Unfortunately the plug-in wings were a major flaw and they frequently folded with disastrous results. What a pity we didn't build something sensible like an Inchworm or a Caprice. Yours,

Same thing happened to a friend of mine when we were about twelve years old. He built a KK Chief and made a beautiful job of it. It was given so many coats of clear dope that it shone but it was also well over weight. We took it to a field to fly it but when it reached the top of the 50 metre towline, the wings folded. He never built a model aeroplane again. He likes to race dinghies these days.

* 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.
