For any tow plane. You may tow any sailplane up to 75lbs / 35kg with this release. However, you still need to follow all safety guidelines and rules as established by your country's laws, modeling association, club, etc.

Made from high-strength aluminum. Offers two release functions because of elaborate fabrication. Even double tow with two sailplanes at the same time with converted release of both sailplanes is possible. When towing a banner, a second function may be realized, such as dropping a sky diver.

This release may be attached to a rib or frame via two M4 counter sunk screws (included).

Diameter at bottom measuring the round area: 14mm/0.55"

Diameter at bottom measuring the flattened area that attaches to the frame or rib: 12mm/0.47"

Diameter of ring right below where tow release line feeds: 16mm/0.63"

Total height: ca. 50mm/1.97"

Height from bottom to lower end of ring: 33mm/1.3"

Total weight: ca. 11g/0.39oz.

This package includes: one tow release, two M4 screws, one threaded rod.

This release may be screwed to the fuselage top via a M12 cap nut (included).

Diameter: 12mm / 0.5"

Diameter of ring that will rest on fuselage top: 21mm / 0.8"

Total height: ca. 40mm / 1-5/8"

Total weight: ca. 24g / 0.85oz.

This package includes: one tow release, one M12 cap nut, one threaded rod.

For sailplanes up to 15lbs./7kg. 60mm/2.36" long. 8mm inner diameter. 10mm outer diameter.

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

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.

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
