Vigor VSD-11YMB MG/HV Extra Large 360 Degree/Winch Servo 0.75sec / 40kg / 150g

It is a heavy duty servo so will need a good power source,what are you using to power the servo,is it a battery or a BEC system.

If using a BEC - go for a 7.2v BEC off 3S or 4S batteries.

I've had the same thing with some budget sail winch servos I bought in the UK - which seem to be the same one HK allegedly sells (maybe one day they'll be in stock). I think the answer is they expect transmitters to send a wider pulse range than Futaba or Hitec use. I can get more range by using a cheap chinese servo tester. Have you tried setting the end points to 125% (or whatever the limits are)? I'll have to try that too.

Go to ****vigorprecisionltd**** to get pdf file for this servo. Spec. sheet claims to have same spline as futaba. I will try to upload the file in the file section today.

Well worth reading. Thanks. So, the HobbyKing specs are total nonsense. I find it a bit disturbing to see a servo manufacturer quoting stall torque in "oz/in" though. You don't divide force by distance to get torque, you multiply it. Force times distance. Kg.cm or oz.in, people. Not Kg/cm or oz/in. Makes you wonder what it is they do for a living...

It depends on the length of the pulses sent to it by the receiver or the servo tester. For pulses of 1ms to 2ms, you'll probably get four turns. It looks like they expect the full range to be 0.9ms to 2.1ms or maybe a bit wider. It's possible theres' no limit in the software, other than maybe rejecting short pulses. If you have a microcontroller (e.g. an Arduino), you could try sending stupidly long or short pulses to see what happens. Modifying them to do continuous rotation shouldn't be hard - uncouple the position sensing pot (assuming that's how they work). I've done it with standard servos, but had to cut off the end stops too. Modifying a sail winch should be easier.

Apparently, they expect the full range to be 0.8ms to 2.2ms. I think Multiplex use that standard, Futaba and Hitec don't, as far as I know.

Hi, my purchase is two of them and only 4 turn with end point to 120%, why???? I HAVE A TURNIGY 9x

Bondo something suitable to their spline

Probably not directly. I tested mine on ~6V, with constant cycle on servo tester - it was hot after few minutes. Ofc servo on tracker won't work non-stop, but as pan-tilt system with stabilisation... Anyway, even smaller servo could move DSLR easily, with that one (and 360°* rotation) You could pan-tilt beer barrel easily =)

what does 'ofc' mean and are you saying it would or wouldn't be good as a pan servo on a heavy duty antenna tracker? does it only come with the winch servo 'horn' or other types as well- I would need this with a regular round servo horn- if not- do you know where I could get one? thank you again

 theSelf 45 points

Where can I find different servo horns that will fit this? the winch horn isn't appropriate for my FPV pan/tilt antenna tracker needs- thanks in advance

 ABLomas 37 points

ofc == "of course". Servo comes with round "horn" (like gear pulley) and no other horns. Servo horn mount looks like it should fit other big servo horns, but i do not have another large servo to test it. Few big bluebird servos should arrive soon, i could test if horns could be fitted...

 theSelf 45 points

Thanks-would be good to know if any other horns fit this servo for sure

 ABLomas 37 points

Tested with BlueBird 661DMG HS. While they're big servos, their arm connector is much smaller compared to this servo. No idea who could fit. Probably You could make custom servo (carbon plate drill dremel)...

 theSelf 45 points

OK- thank you for trying and your replies- I have tried contacting Vigor to see what they have to say-so far they siad that the VSD-11YMB & VSD-22YMB really have a similar cycle horn as hitec hs-645mg which would be great if it did- but clearly it is a large winch horn which is no good for my antenna tracker.. will report back if they give any better info

NEW...NEW....NEW...try some CA or Epoxy and make your own,be a MAGYVER!!!!

i think mounting a servo horn to this servo is no option. it will rotate 6 times and is very very very powerfull. (and very heavy too). you can offcourse program the radio so it will get a maximum of just 360 degrees and mount the cam right on. but i think for fpv flight 180 degrees is more then enough. and to do so you only need to buy a servo angle expander for a few dollars and check a simple light servo if the expander don't force it into its mechanical end.

HI,

it's a sail winch. not a normal servo.the six revs are the total amount of rotations

 Nozzy 2 points

This servo will rotate 3x360CCW from center and 3 x CW from center, so yes it will rotate both ways.

 larryross 8 points

You might try cutting the center out of your pulley and bolting in the spline from one of the control horns. Might work if your application isn't a high speed rotation.

has anybody tried to wire up a battery pack to the winch.. I want to run 7.2 volt. to pick up the speed.. but i cant seem to get it to run.. when the winch runs off the reciever pack.. no problem. but wire up a different battery . no motion at all. i like the winch. just need some help with the other battery pack thanks
