A powerful high specification digital sail winch servo with metal gears that can be programmed to operate from 1 to 6 turns (controlled by end point adjustment). This sail winch servo can operate up to an impressive 14.5kg of torque so it is perfect for the larger yachts.
Turns: 1-6 programmable
Voltage Range: 4.8~6.0V
Speed: 0.72~0.60sec 360°
Idle Current: 0.12~0.14A (No load)
Working Current: 0.40~0.50A
Stall Current: 1.80~2.20A
Size: 40.3 x 20.3 x 38.7mm
Drum Diameter: 35.5mm
Connector: JR style with wire length 265mm
Spline Count: 25
Unit Weight (g):
Very good value good replacement for drum sail winches.
Note must use computer aided radio to set end points and
turn radio on before boat and turn boat off before radio.
used on Marblehead rc sailboat with A-Rig on in 12 to 15 knots
of wind winch had no problems sheeting in the rig even though
the boat was over powered conditions were B-rig borderline C-Rig.
mikeHi, I bought 2 of these (1 for a spare) and found that unless you can programme them, they can cause a lot of model damage. For example: The winch works fine if the servo pulse is KEPT between the accepted standard of 1 to 2 mS. With both of mine, if a pulse gets down to around ).8 mS, the servo will CONTINUE to rotate until something breaks. An example where this might happen is with the Turnigy 6XS Tx, whose throttle (winch) output goes to 0.75 mS if the radio is switched on without the throttle stick at "idle"...Crunch! Also, with the end travels set at 100pcnt, all chanels go outside of the magic 1 to 2 mS "standard".
Please, HobbyKing, bring on the programmer/instructions. This is not a cheap servo and can do a lot of damage, if travel cannot be limited.
