How to make a servo winch 3

- So this is my newest version of a servo winch. I used a mini size servo because of its increased torque compared to a micro servo and smaller size than a standard servo.It also has a full size main gear that allows me to drill through, a micro servo doesn't. This winch will be used on my scale 1/24 rig. I used an internal reel system and used steering rod bushing from sumo crawler as guide for cable. M3 bolt was used to go through back plate of servo into back of main gear giving it another point to distribute stress of pull. Two m3 lock nuts sandwish a 3mm washer to servo as internal backplate for reel. All electronics were taken out of servo to make room for reel and will be used outside somewhere in rig (not sure yet where I want them). Video runs kinda long but if you want to see fully assembled winch look at last 30sec on video. Thanks for watching and please leave any questions on comment area so others can benefit from them. Oh and by the way like or dislike, but if you dislike let me know why so I can work on making better videos, thanks again! PS: if you want to do away with POT or resistors all together a small esc can be used to control winch, ebay has 10a esc for $10 shipped that can handle 2S and work great.

Thanks for your support, its because of viewers like you that I keep trying to better the stuff I do, a lot of people watch the videos but not to many ask for specifics, the whole servo winch series has been doing real good and I figured it was time to give you guys something better.
Thanks, just figured maybe I wasn't the only one out there that could use this info :)
great info and idea
Awesome! Best one I've seen so far and it gave me some great ideas. Thanks!
No problem my friend, glad it helped out :)
Very cool!!! Iv been following your winch building for sum time now and this one is VERY sweet!! I really like the seamless design!!!!!!!
excellent
getting closer, just got slowed down by waiting for these servos to come in mail but it shouldnt be much longer before getting the whole thing up and running, thanks for checking out video
cool cant wait to see yr scale rig
Awesome, I'm going to have to try and make one.
Perfect tutorial!
Super. Like this design very much.
+Harry Cash thanks, just trying to make something that can be hidden if you dont like the "look" of a servo winch as opossed to a scale looking one.
It would work awesome on one of your 6x6, should have enough power to pull any of the two up any hill! :)
Very cool design!
I wanted to ask:
Is it possible for this design to be used with a thin electric cable instead of the pull wire? I want it to pull a led bulb. How would i connect the other side of the cable to the case without getting it tangled up?
Can this be controlled using 3rd channel with 3 position?
Are you able to control the exact positioning now that the servo is able to turn multiple times?
+Minh Nguyen You control the speed at which it turns and the direction but final position will be at the point where you let off the throttle. If you use a esc that has drag brake built in it will help the servo keep its spot if you were to try to turn it though. As far as returning to neutral(start position) it wont happen as it no longer has a pot to give it reference as to where to go back to.
Can the potentiometer be wired externally to the truck to act as a controller if there is not a third channel present?
I think you might run into more difficulty running a set up like, 3ch transmitters are kinda cheap now, maybe save up a bit for one so it can work better? its just the pot is not as accurate.
Thanx
This wouldn't work because the servo needs power and signal to function. Without signal (pulse duty modulated) it will go into neutral / not move. You could make an external driver with a 555 timer but by the time you did that, better off with an extra channel on your radio.
