About this Plan
Hegi Kadi. Radio control glider model. Wingspan 1880 mm.
Note box art [pic 003] shows this kit can be built with either a straight dihedral wing or polyhedral wing layout.
Note plan also shows optional power pod for 0.8 cc engine.
Quote (google translated from the German): "Specification for 331 KADI. Glider model for free and RC flight. 'KADI' is a high-launching glider model that can be used as a free-flying or remote-controlled model and that is particularly enjoyable as a motor glider in conjunction with the 'Zechmann-Tank' (Order No. 224/1).
The wings of this model can be built straight or with 'ears'. However, it is necessary to decide on one of the two options before starting construction. The kit includes the material for both versions. The construction plan also contains a separate drawing for the version with ears. The plan was numbered in such a way that you can build without longer interruptions and waiting times if the sequence of numbers is taken into account.
In addition to the building plan, parts list and instructions with perspective drawing, the following tools are required: balsa knife, razor blades, jigsaw, sanding block, fine and coarse sandpaper (Order No. 275/10 and 11), pins, small hammer, brush and finally a straight building board.
Before beginning any work, the relevant section of the assembly instructions must be read thoroughly.
All punched wooden parts are to be cut out with a balsa knife or a razor blade and lightly sanded down with fine sandpaper. Hard or contact adhesive or white glue (eg 'Ponal') is used to glue the wooden parts if longer drying times are not important. Metal connections are made with the help of 'Stabilit-express' or 'UHU-plus'. Hard and contact adhesive are included in the box.
Construction of the fuselage:
Parts 1 to 41 are required. Each of the two fuselage side parts 1 consists of two halves, which are glued together with hard glue according to the plan. The reinforcements 2 are to be glued to the inside of the two side parts at the front with contact adhesive, so that a left and a right side part are created. Then use a pointed object to pierce the markings for the holes for the steel wires 38, which will be inserted later.
Cut the triangular strips 3 to length according to the plan and glue them to the side parts with contact adhesive. The slight curvature of the lower triangular bar results from the shape of the side panel. Glue reinforcement strips 4 and 5 to their positions marked in the construction plan. The lower and upper triangular strip is to be ground conically from frame 13 to the rear (please note the plan). At the end of the fuselage, the strips must be flush with the side panels..."

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

User commentsHello, the KADI was my first sucessful rc-model. Maidenflight 5th of June 1972, crashed by a broken wing on Jun 17th 1974...

Hello, here are two pictures of my Kadi taken 1973, the first [main pic] shows the Kadi with Cox QZ engine. Second [pic 005] is with Taifun Sprint.

The first picture is showing my little brother (background with glasses), me at the age of nearly fourteen in early spring 1973...The COX QZ had barely enough power to raise the Kadi in the plains, in the valley, where our airfield has been at that time it did not work...In Summer, after my birthday we changed to the "Taifun Sprint" 1,76 ccm, it raised our "Kadi" like a Boeing 727...It flew in this shape till the wing broke during flight in 17th of June 1974...

* 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.
