Description
Towing Winch MEDIUM from UniLight.at
The Unlight.at towing winches are a new milestone for the F-tow in model flying. With the winches, it is now possible to catch up with the tow rope completely automatically after the release of the glider and to safely fly and land with figures on the descent. The intelligently controlled automatic retractor allows numerous possibilities for beginners and professionals. The functionality, electronics and software of the winches are identical, it only differs the installation situation and the size in the model.
Model WINCH-MEDIUM was built as a robust standard version and can tow gliders up to 25kg.
The winches consist of CNC manufactured aluminum parts and milled fiber composite panels. This allows us to achieve the lowest weight with maximum strength. The drive is a light, brushless motor with a non-blocking belt drive. The motor output stage, the entire control electronics and also the servo for emergency shedding are already integrated. Each wind is accompanied by a high-performance uniLIGTH.at flashlight, with which the operating status can still be seen from the ground.
Each winch is configurable via the uniLIGHTPLUS interface and our software *

Functionality
Plug the 2-pin JST power cable into a 2S LiPo battery. Then connect the 3-pin servo cable to the receiver and switch on your reception system. Make sure that the servo position is approximately in the middle position. There should be several beeps with a small and then two beeps with a longer distance audible. Depending on how the servo position is changed, different functions of the winch are activated. Configure your transmitter to ensure easy and reliable selection of functions; in particular, the emergency shedding must be quick and safe, but not accidentally reachable. Depending on the manufacturer of the transmitter, this can be implemented flexibly and elegantly via encoder settings and mixers.
Winding speed: As soon as the functions can be selected from the transmitter, please make sure that you have the correct, selected winding speed. Also pay attention to the flashing signals of the RED LED in the housing or the external power LED. Note that slow winding will result in a better bump and fewer knots.
Hooking in the rope: To hook in a new rope, turn the spool so that the notch for the rope lock is easily accessible. Then guide the rope through the hull entry first and then through the cable guide of the winch. Depending on the installation position and skill, you can now lock the rope immediately by setting the switch position back to normal or 0%, the locking pin will close slowly to allow some time for positioning. Then check that the rope is securely locked.
Winding up: To wind the rope, bring the servo position into the -75% range until the winding process starts slowly. If you are not in the air, hold the rope back slightly to simulate the aerodynamic braking effect. When the stop (ball or similar) is reached, the electronics of the winch will recognize this by the absence of rotation of the coil and the increased blocking current. Depending on how much was wound, the automatic tries to repeat the process a few times to be safe in the end position.
If the servo position is not returned to normal operation, the automatic will respond to any attempt to unroll the rope.
