Towing coupling with hi-start hook for 20 mm servo Wemo # SK-F

The towing coupling is particularly suitable for models with FES motors, as the tow rope cannot be used through the nose of the fuselage due to the motor.

The coupling can be installed anywhere on the fuselage.

Additionally, a hi-start hook can be inserted into the towing coupling. This allows the model to be launched over a slope edge when flying in alpine terrain.

• Made from high-strength aluminum AW 7075
• Brass body with very strong spring and 3.0 mm steel pin
• Miniature Bowden cable with steel core and 1.3 mm steel wire / galvanized
• Servo mount made of black GRP (with abutment for the Bowden cable) for 20 mm standard servo
• 4.0 mm wooden board for gluing into the fuselage and mounting the servo holder
• 2 wooden adhesive pieces for laying the Bowden cable
• Clevis M2 (steel wire is soldered directly into the clevis)
• Screws and lock nuts in M3 for servo installation
• Very low profile, allowing, for example, batteries to be installed above the coupling

By using the Bowden cable, the servo for operating the pin can be attached at any conceivable position in the fuselage. This creates entirely new possibilities.

The hi-start hook has an angled 5.0 mm stainless steel pin, which is pinned and glued to the insert. Due to the oval shape, the insert can be very easily inserted into the towing coupling from below. This works immediately, we promise. The locking then takes place via the pin.

Similarly, due to the oval shape, it is very easy to position the rope loop when attaching the tow rope. The loop is virtually force-guided and cannot rotate. This also works immediately, we promise. The locking then takes place via the pin.

ATTENTION: It is important to note that the locking pin is spring-loaded. This means that after releasing the tow rope, the button/switch on the remote control must be returned to its initial position, otherwise the servo will constantly have to work against the spring force!

Length of Bowden cable / steel wire = 500 mm / 550 mm (other lengths can be produced if required)

The kit includes all the necessary parts for assembly (see first picture with all parts).
