About this Plan

Wenzel. Free flight A3 towline glider model. Wingspan 678 mm.

Quote (google-translated from the German): "Building instructions: The wing construction: Directly on the plan protected with a transparent film (caution: The left wing tube is not shown!) Sand the ribs together in one block. We also make the spar incisions in the block. The ribs (except for the outer ones) are glued to the lower chord of the wing center panel, then the upper spar chord is inserted, then the leading and trailing edges.

We glue the precisely sawn connectors to the ears between the ends of the bars. (The respective rib has to be severed here and glued in two parts.) Finally, we use glue to insert the 3 mm balsa spar webs between the two spars, the grain of these balsa strips running across the pine slats, ie 'standing up'.

We build the wing ears in the same way, but without the balsa spar webs. The ears are then connected to the middle section and aligned precisely so that the V-shape is the same on both sides. Put small triangles from 3 mm balsa in the creases on the ribs. Finally glue on the wing tip and sand down the wing.

The construction of the tailplane: easy to see from the plan, largely identical to the wing, only made with less material thickness.

Building the vertical stabilizer: This is cut out of medium-hard 2mm balsa, the rudder is cut out and over two strips of thin aluminum sheet.

Construction of the fuselage: The fuselage head is sawn out of 10 mm basswood. It is also possible to make it out of balsa wood. The tail boom consists of two 2 x 10 pine strips between which a filling of 10 mm balsa, ground down to 6 mm at the end, is glued. Once the tail boom is glued, it is also planed or filed down the sides so that it narrows to a width of 7 mm.

The ballast compartment is cut into the fuselage head, the tail boom is glued into the cut-out (straight!), everything is sanded and the fuselage head is glued on both sides with 1 mm plywood. Press well, if necessary at least press together with clothespins on the sides. The holes for the retaining dowels of the wing and the tail unit are made and the pins (bamboo) are glued in. Mount the support plates for the wings and tail and butt glue the vertical tail to the fuselage; Pay attention to angularity, align all parts precisely..."

Notes

* 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.

Scaling

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.
