Sailplane Tow Release Medium Large Z-281

For sailplanes up to 14kg/30lbs. 80mm/3.55" long. 10mm/0.9" inner diameter. 12mm/0.47" outer diameter. Latch is 3mm/0.11" thick.

 

It is mandatory to clean and sand all areas on the release and in the fuselage that get in contact with epoxy to ensure a strong glue joint.

 

Made in Germany

 

Because this Pro-Edition was made from stainless steel / aluminum, malfunctioning because of moisture and resulting oxidation is almost non-existent. Safe operation even under higher loads and a low release force distinguishes this release.

Why is there no neck on this particular release like on the "Standard" version?

Answer: Glue such as epoxy or UHU Plus Endfest will be applied to the surface of the tube in the front half (about 50mm/1.97in. long) after cleaning and sanding the surface areas on the release and in the fuselage that will be covered with glue. Because of the large surface area, the tensile shear strength, while using a high quality, high tensile strength glues such as UHU Plus Endfest, would equal 42500N = 9370lbs. These numbers apply at room temperature. If the temperature is increased, tensile strength will increase further.

Finally, the tow line exerts its force in a 90 degree angle.

The numbers are based on the technical bulletin provided by UHU.

 

Cleaning and sanding all surface areas on the release and in the fuselage that get in contact with glue is the key for a strong glue joint
