Tiny 3s capable esc for servo winch control

[Itali83]

I'm trying to find the specific eBay special esc that some guys use for winch controllers. Can't seem to find it on my watch list anymore and need one for the servo winch I just built. Don't tell me how to wire a resistor into the existing servo board, been there, done that. I want the esc. Thanks!

I'm not sure what specific ESC you're referring to, but a castle micro ESC will handle 3s & 4s and with the adjustable settings will let you fine tune your line out and line in speed and have instant reverse rather than double tap to reverse
Also how do you wire a resistor to a servo board to handle 3s? I've only heard of that being done to replace a potentiometer to keep the servo from drifting.

I found the mini one I used but it's only good for 2s...so no good, I couldn't find any that were good for 3s except drone esc's and I don't think those go in reverse. You could run a separate small 2s battery ....but if you do all then then you could just get a reg sized esc....anyway...here it is...for $10 you could try 3s...

Sorry for the ramble...it's 230 am and I'm still at work, it's awesome when people call out an hour before they are supposed to be at work.

I knew one of my ascender buddies was doing this. Just couldn't remember which one! It was obviously late for me too because I really only need 2s on this truck. I never run 3s on this one so thatll work just fine. I'll have to give it a try. Thanks!

Keep in mind that has a reverse delay so you will have to double tap to winch line in. Also there is no motor brake. The brake they refer to is the reverse. If you want a smaller and cheaper ESC look for the xys-bl20a it's smaller and 20 amps which should be plenty. It's popular with micro crawlers. Look for one that says. "No brake" for no reverse delay.

All the mentioned escs don't have a motor break to hold the winch line in place while you're paused and it will pull out when you let off the throttle. That's another reason to recommend the castle micro

I use a Wasp robot ESC for the winch in one of my trucks. It can handle 28V of input so 3S is no problem and the overall size is about the same as a Castle BEC. Definitely the best winch controller I have used.

It is me Ben, and I us a wasp also. They are a great esc for the losi micro too."thumbsup"

I assume instant reverse, what about motor brake when neutral?
Spooling out when I don't want is one thing that bugged me with a non programmable ESC as a winch.
I did a quick look at the wasp website but didn't see anything about neutral brake.
I have a few heyok and many castle micros, but I'm always interested in other options.

I use a GT3c and I have plenty of tuning for that channel so no problem.

Ive had hacked Gt3bs since the beginning. I'm not aware of any settings that give the ESC a neutral brake function. How did you manage that?

I didn't say I had a neutral brake function, I said I haven't had any problems with it. I guess what you may perceive as a problem doesn't seem to be a problem for me! What else can I say? :roll:

That cheap esc I posted doesn't have a drag brake, just forward and reverse which seems fine, there is quite a lot of resistance in a servo gearbox. If you pull fairly hard you can pull out line but it hasn't been a problem for me. Especially since the truck itself has a drag brake.

I just run my servo winch off a bec no esc no funky winch controler just a servo running off of the 3rd channel it works great it has 2 line in speeds and one out speed the internal resistance of the servo is more than enuff to hold the rig in the air and thats with a 10lb rig i dont understand why some one would need a seperate controler for a servo winch ive never herd of anyone using a esc for a steering servo so why a winch servo im using the cheap taxtic 300 no fancy radios just basic junk $3 servo cheap radio and working winch thats it and it works great

 

[spoo76]

you dont need an esc or winch controller because youre using the factory servo controller.
Using an ESC for a servo winch isn't the same as using it for a steering servo. Yes it wouldn't make sense for a steering servo. For a servo winch you'd use an ESC for the same reason you'd use a winch controller. They can handle more voltage, more current, and some people get servo drift. sometimes it started as an old junk servo with a burned out board and they use this as a better replacement. Not all servos are created equal. Yours may be fine on stock electronics for your use. Others may not.
In my case I'm not even using my servo winch. I still haven't burned out my scale winch motors, but I've never run them on the stock controllers

If you just center the pot & add a spool, then it's limited to the max voltage the servo normally can take. That's usually 6v or 8.4v. In most cases it's difficult to adjust actual speed, particularly if it's a cheaper servo that kicks the motor on at full speed. Some controllers have a protection feature to prevent overheating - if it thinks it's taking too long to reach the desired position, it stops the motor til you return controls back to neutral.

When you remove the controller, you're left with just a small brushed motor. Using a small ESC lets you use any voltage, the limit being the ESC input voltage. Holding 10lb in the air is different from pulling a flipped 10lb rig up a steep incline.

Same here.

I don't really know if the Wasp has a drag brake but it has been rock solid and the winch has never crept a mm during use.
