Towing Winch MEDIUM

THANK YOU FOR YOUR UNDERSTANDING! Our 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 * Dimensions: 62x92x84mm Additional weight to the conventional system: 160g Towing capacity: recommended for gliders with up to 25kg Emergency discharge: integrated Hull implementation: included Total weight: 235g Winding motor: busless, non-blocking belt drive Winding space: e.g

40m / 0.8mm rope Winding space: e.g

35m / 1.0mm rope Winding space: e.g

30m / 1.5mm rope Winding space: e.g

25m / 2.0mm rope Power consumption: 20-25mAh per tow plow Power supply: 2S / 8V Lipo Receiver: 1x Servo UNI, galvanically isolated, HV suitable Construction: GRP, aluminum Signal light: uniLIGHT PRO16F-080x2-RT enclosed 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

    Instellation of the cable guide     The winch itself can be noted on the fuselage bottom or a carrying bulkhead, the cable guide, however, must be mounted cleanly above the winch in the back of the fuselage (there were already successful implementations with "tail drag" as in the original models)

Make sure that even here very high forces can arise during towing and look for a correspondingly massive spot

Also, make sure that a rope dropped in an emergency can whip at high voltage - there should be no systemically important components in the possible impact area

Figure 1: be sure to mount the bushing exactly above the winch along the vertical axis of the model

If the pulling forces are not introduced straight into the mounting points, damage to the axles, bearings and housings can easily occur

Figure 2: Along the vertical axis, the hull infeed can be set flexibly

Just make sure that the rope always runs over the brass axles and does not rub permanently on a fiberboard

The straighter the introduction, the more reliable the winding process will be

  Installation position in the model     The tow winch can be mounted horizontally on the hull bottom or vertically on a supporting bulkhead

This is basically indifferent to the function

It only has to be ensured that the winding direction is selected correctly for the corresponding installation position

If the preset orientation is not correct, then this can be changed via the uniLIGHTPLUS interface, or two lines of the motor can be crossed out
