Towing Winch SMALL

The uniLIGHT tow winches of the 3rd Generation represent another milestone for F-towing in model flying. With these winches, the towing can be operated extremely comfortably and safely in everyday use. The tow rope can be automatically reeled in after the glider releases, ensuring a safe flight and worry-free landing. The intelligent reel-up mechanism offers numerous possibilities for both beginners and professionals. The functionality, electronics, and software are identical across all models; only the installation size, weight, winding capacity, stiffness, and thus the application areas differ.

The SMALL standard version for ambitious towing, optimized for minimal size and weight, ideal for electric operation and gliders up to approximately 10-12kg, with ropes ranging from 0.8mm to 1mm in diameter. 

The winches are made from CNC-manufactured aluminum parts and milled fiber composite plates, achieving the lightest weight with the highest strength. A lightweight, brushless motor with a jam-free belt drive is used for the propulsion. With a slip clutch, the winch can also function as an electric spring. The motor end stage, all control electronics, and servo for the emergency release are already integrated. Each winch comes with a powerful uniLIGHT.at strobe light, allowing the operational status to be visible from the ground. Every winch can be configured via the uniLIGHT PLUS interface and our uniLIGHT.DESK software for Windows and Android.  

In its default state, the winch operates universally in manual mode, allowing for towing, winding, and emergency release. Additional intelligent functions can be activated via the DESK software. First, the rope length must be calibrated, meaning the length is stored. Numerous functions become fully available once this is done, with the key systems being:

• Intelligent release: The rope is only released once it is almost fully unwound, preventing accidental unspooling on the ground.
• Dynamic towing with electric spring function: This can be set for a specific rope length, so the glider will only be towed up to that length and then gently stopped.
• Manual, intelligent reeling: Can be activated during towing if the rope sags. As long as there is movement in the rope, the function remains active; it automatically deactivates when the rope is still or fully extended.
• Remaining rope function: Determines how much rope is actually reeled in. This value is fully adjustable and can be tailored to the towing model.  
• Remaining rope reel-up: Automatically reels in the remaining rope when the model is stationary on the ground. 
• Configurable winding speeds in all operating modes.
• Manual optimization of all parameters or automatic setting after the learning process.
• Galvanically isolated system with master-slave shutdown does not require its own switch for power supply.
• Operable with only one servo channel, 2S LiPo/LiIon as power supply.  
• Under-voltage protection safeguards the battery while still allowing the emergency release of the rope in a classic towing operation.
