About this Plan
KK Chief. A2 Nordic class towline glider. Wingspan 64 in, wing area 515 sq in.
Quote: "The CHIEF is an advanced contest design to the A-2 Nordic specification. Good looks combined with outstanding performance were the main object in mind when the model began to take shape on the drawing board. The features which were felt to be essential were as follows:
1. Plug-in wings, for ease of transport.
2. Knock-off-ability, in crashes.
3. Good lines.
4. A safe, reliable and easy to build dethermaliser.
5. An auto rudder, to ensure that whilst the model went up straight on the line, a turning flight would result when it was released.
These features are all to be found on the model, together with the structural strength necessary to stand up to the strains of towing up in all weathers.
In spite of the graceful contours, the construction of this plane has been kept as simple as possible. The basic framework is built up from 1/8in square - formers being added top and bottom. The only tools needed are a packet of steel pins, a pair of long nosed pliers, a fretsaw, sandpaper and plenty of razor blades. Use the single edge type or one of the more popular two edge type broken in half. A KK balsa knife is preferred to razor blades by many modellers and is certainly much safer.
Protect the plans by placing greaseproof paper over them. Cut out the sheet parts only as you need them - to avoid damage or loss. The back of an old hacksaw blade is useful as a straight edge when cutting along straight lines on the printed balsa sheets."
Added printwood formers, thanks to jfkitson.

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

I lost a KK Chief from a place called 'The Coppice', which overlooked Accrington Stanley Football club. Must have been about 1958, and had taken me months to save up for. I was having trouble trimming her, so left the DT off. Got sucked away in a massive thermal, never to be seen again. Looks like I will be downloading the Chief from Outerzone over the next few months and having a go at bungee launching. RC of course.

My Keil Kraft Chief [more pics 004] has had a 'makeover'. Recovered in the scheme that I remember as a child from the Keil Kraft leaflet (which was in monochrome) [model photo & more pics 005].

* 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.
