The uniLIGHT towline winches of the new Generation 3 represent another milestone for F-towing in model aviation. These winches make it possible to enjoy towing operations with extreme comfort and safety in everyday use. After the glider is released, the towline can be retrieved fully automatically, ensuring a safe flight and a worry-free landing. The intelligently controlled automatic reeling system offers numerous possibilities for both beginners and professionals. The functionality, electronics, and software are completely identical across all models; the only differences are in installation size, weight, winding capacity, rigidity, and thus their respective areas of application.

The LARGE standard version for ambitious towing, with an enlarged winding space suitable for thicker and longer ropes, rated for use up to 25 kg, large rope guide, and ropes with a diameter of 1.5 to 2.5 mm

The winches consist of CNC-machined aluminum parts and milled fiber composite plates. This allows us to achieve the lowest possible weight with maximum strength. A lightweight, brushless motor with a non-locking belt drive serves as the power source. A slip clutch therefore also allows operation as an electric spring. The motor output stage, the entire control electronics, and the servo for emergency release are already integrated. Each winch comes with a powerful uniLIGHT.at strobe light, allowing the operating status to be recognized even from the ground. Each winch is configurable via the uniLIGHT PLUS interface and our uniLIGHT.DESK in Windows and Android.

In its standard configuration, the winch is simply operated manually, allowing for towing, winding, and emergency release. Additional intelligent functions can then be activated in the DESK. To do this, the cable must first be programmed, which means the cable length is saved. Numerous functions are only fully available after this; here are the core systems:

• The intelligent release only allows the rope to be released once it is nearly fully extended. This prevents accidental deployment on the ground.
• Dynamic towing with an electric spring function can be set for a specific rope length. The glider is thus pulled only up to this rope length and then gently stopped.
• Manual, intelligent reeling can be activated at any time during the tow if the rope sags. As long as there is movement in the rope, the function remains active; when the rope is at rest or fully extended, it is automatically deactivated.
• The remaining line function determines how much line is actually retrieved; the value is freely adjustable and can be adapted to the towed model.
• The remaining rope rewind function can automatically retract the remaining rope when the model comes to a complete stop on the ground.
• Freely configurable winding speeds for all operating modes
• All parameters can be manually optimized or automatically set after the learning process.
• Galvanically isolated system with master-slave shutdown requires no separate switch for the power supply
• Operable via a single servo channel, 2S LiPo/LiIon as power supply.
• Undervoltage protection safeguards the battery but still allows for emergency release of the line as a classic tow.
