The remote controlled, operating winch comes complete as pictured. The winch mechanics are small and compact to fit inside a winch mount enclosure
like the Baumann B307116 Winch Mount that is commonly located externally, just above the cabin door or inside the cabin with a swing arm
that pivots when the cabin door is open. This online instruction manual is a translation from the original and may vary slightly.

The following instructions are here to help modelers install and setup their remote winch. Each component is straight forward to install but a little
extra help makes this task even simpler. |

Scale Winch
B307112
1. Geared winch unit with cable guide.
2. Red winch weight.
3. Servo controlled switch unit.
Maximum payload weight is 90 grams.
|

Control Switch Installation:
Mount the switch unit into the model and secure it close to the receiver or in an area that can be accessed to make adjustments
to the servo.
1. 6V (5cell) Battery power for winch.
2. Switch motor lead, mates to winch.
3. Servo connector to receiver.
Remove the servo horn, connect the servo lead to an auxillary switched channel, preferably a 2 or 3 position switch and center the channel
before installing the horn in the neutral position.

Winch Installation:
The winch has two mounting points that are designed to match with Baumann's winch housing but are perfectly suitable for a custom
winch mount. As in the photo, looking at the top of the winch unit, the flat mounting surface remains vertical when installed in the model.

Before Operating:
Only use the winch while hovering otherwise the cable could become tangled in the rotorhead!
1 + 2. The winch will automatically stop at both ends points, but ensure nothing interfers with the cable guide's movement.
3. To allow the hoist cable to raise and lower freely, there should be no obstructions below the winch.

Notes:
As with any mechanical switch assembly, it is vital that the servo toggle the switch smoothly without binding the servo at its end points.
Most modern transmitters have subtrims on their auxillary channels to handle this exact problem, however if you radio does not have this functionality,
there are two alternatives. First the servo throw can be manually adjusted by drilling a new hole at the correct distance from the center of the servo
so that the servo can move to its end point and not bind against the switch. Some trial and error is necessary to get it just right. The second method is
to replace the pushrod assembly with a version that has a built in servo saver, as more commonly seen used for gas powered car/boat carburetors. Our only
caution in using such systems is to ensure there is no vibration induced interference from the servo saver.
No matter which method you choose, thorough testing is the best approach. Using a common volt meter, attached to your receiver, check for voltage
variations (drops) when the winch servo is at both endpoints. Sometimes you can rely on listening to the servo for buzzing, but this has not been proven
reliable as what seems perfect on the workbench commonly becomes an unseen problem when in the air.
