Training glider "Zerstörer".
The "Zerstörer" glider described in the following illustration and shown in the accompanying drawing is a braced monoplane with a short canopy and a removable tail. The aircraft is particularly suitable for training and was donated to the Hamburg Aviation Club (Flugtechnischer Verein Hamburg e.V.) by its owner, a member, specifically for this purpose in November 1926. The aircraft was designed and built by engineer Hans Wagener, Hamburg, and has proven its strength and good flight characteristics through more than 50 flights.
The aircraft has a wingspan of 12 m, a length of 5.90 in, and an area of ​​18 m². The wing loading is approximately 10 kg. The approach angle is <5 rad, while the angle of attack in flight is approximately 5.6 degrees. The wing is in two parts and is braced towards the canopy by four equally long spars. To ensure easy repair in the event of a wing break, two 125 mm high plank spars are provided. and 15 mm wide, which are further reinforced with 1 mm plywood at the attachment points of the rods. Up to the front wing, the wing is covered with 1.5 mm plywood without the need for a special nosepiece.

In the middle, both wing halves are attached to the boat superstructure with just two bolts. The middle boat superstructure is particularly strong and similar to that of the Pegasus. The boat itself is very light, as it does not have to absorb any special forces. A door is attached on the left side for easier boarding and disembarking.

The lattice tail can be removed directly behind the boat and is braced by six steel wires to the rear wing spar at the attachment point of the struts. Two cables also run from here to the bow of the boat. The elevator is split and has a triangular damping surface in front of it, which is supported by two rods after the lower lattice tail spar. The rudder is balanced. The last section of the tail is covered with fabric and thus also serves as a steering surface. All control surfaces have proven to be perfectly adequate. The control system is standard stick steering. According to measurements from previous flights, the destroyer's glide angle is 1:15.
Assembly and disassembly is very quick, as the aircraft is braced and the lattice tail can be removed. This also means that it takes up very little space when disassembled.
