Hitec RCD 33785S HS-785HB 3.5 Turn Winch Servo

This is an excellent but expensive winch servo, so it is tempting to use both drums to pull in two sails. As other reviewer notes, this can lead to problems. I am using a servo for EACH sail - One drum pulls a sail in one direction, and the other drum (wound in the opposite direction) pulls the same sail back in the opposite direction. The sail is under control at all times, even if the wind changes suddenly. I thread the cable round several pulleys under the deck to get correct geometry, and of course there is extra weight from needing 2 winches.These winch servos give incredible torque, I use these on a 51 inch long Thames Sailing Barge, displacing about 40 pounds, so for me its a perfect solution. For smaller boats this may be over-kill but there are just not many other winch servos to be found.

This winch works very well for main sheet and jib sheet on the model sailboat.

Great product for 1meter sailboats. 3.5 turns is just perfect for 10-15" of travel for sail movement. I ordered two but one would continue to search for end points. Sent it back and got a refund. I will order two more to have just in case, but will test each for proper operation before I save to my spare parts box. Keep in mind that a winch drive needs special set-up conditions to operate properly. You can find some options on the Internet. I use a three level thin plywood pancake with three standoffs at each corner that surrounds the drum in case the line comes off the drum. If the line screws up just let it out all the way and wind it back in. With the three layer pancake and no pulleys or rubber band you need to keep wind pressure on the sails whenever you let the sails in or out.==---------== Top Ring of Drum[ ]==---------== Center Ring of Drum[ ]==---------== First Ring of Drum[ ]====================== Top Level of Servo MouGet thin plywood as close to the same thickness as the drum rings and about 1/2 inch past each sides of the drum. Cut a circle out of the center of each piece of plywood.(Three pieces)Use dowel or square spline as spacers in between the corners of the plywood spacers.(Twelve pieces)

WAY more powerful than my stock spektrum steering servo, but it's considerably larger and required quite a bit of work to make it fit the stock servo mount.

Es de buena calidad y funciona perfecto

Used on my losi dbxle v1. Tight fit into servo box but with a bit of silicone spray will slide in. Have had for about 18 months and has help up well.

This servo is awesome! I'm running it on 7.4vt, and it's fast and strong enough for all my 1/5 scales vehicles.

We ourselves in the RC community are very displeased with hitec's new blue Servo design. The new color they've chosen is so very unattractive looking for blue and it's not compatible with most platforms. The color doesn't go with scheme so what's your setting up your RC to look like with upgrades email hi-tec tell them we want them in black which is a neutral color. We will not buy the new ones anymore. Until this color issue is fixed
