Quote: "hello Mary and Steve, first, thank you for your amazing webarchive of planes and collecting them.

I have the original plans and instructions from the [original, 1970s] Robbe Marabu 6 for you. Feel free and put it on your site for publication and for other modelers who want to rebuild it. This plane is a dream of a thermal catcher.

I have reconstructed the glider and Robbe is producing and selling it again [in modernised form] as a kit now. Look here

Quote (google-translated): "Assembly instructions and parts list for the robbe "Marabu 6" assembly kit, Order No. 3154.

The Marabu 6 is the product of a series of high-performance models. The model is designed as simply as possible to ensure quick and uncomplicated assembly, even for less experienced modelers.

The Marabu 6 has a pendulum rudder. If flown with a dual-channel system, this must be locked. Determine the angle difference between the pendulum rudder and the wing precisely according to the plan!

Although it is generally customary to start building a model with the fuselage, we suggest starting with the wing and horizontal stabilizer for this model. The advantage is that the wings and stabilizers can remain clamped to the construction board while the fuselage is being constructed. This is definitely beneficial because any stresses that may have occurred during construction are equalized during this time. The finished tail unit halves are also required for aligning the pendulum control arm and the connecting ribs.

To begin, all rough parts are checked for completeness according to the parts list and pre-sorted according to the model parts. Fuselage side panels, wing spars, etc, must be cut and jointed according to the plan. These preparations will facilitate the quick roughing of the model, as described below:

Wings: The wings consist of parts 1 to 45. We begin by building the left wing half. The plan is tacked to the building board and protected with tracing paper or polyethylene film. The wing is assembled on the building plate with the top of the profile facing down (see building board sketch). To support the rib ends, the auxiliary strip I (46) is tacked to the dashed line. From rib 2 to rib 4, auxiliary strip I must be raised with a 1.5 mm balsa strip (for later planking). The upper main spar is tacked to the building board exactly as shown in the drawing, with a 1.5 mm thick balsa strip (49) underneath.

The ribs can now be glued in place perpendicular to the spar. The root rib (2) is inserted using the angle template (48). After inserting and gluing the lower main spar (31) and the leading edge (32), the lower trailing edge planking (33) is beveled at the trailing edge and glued on. Before the lower leading edge planking (34) can be applied, it is carefully sanded to match the rib contour. (Up to this stage, see Figure 1).

After drying, we turn the wing half over and place the auxiliary strip II (47) under the end edge (see cross section C-C) to maintain the cast when planking the upper side. The upper end strip planking (33) must be glued to the rear, beveled end with contact adhesive..."
