dumb question but most likely know the answer...

[arcanecrawler89]

So iamb finally looking at getting a winch on my dingo but I have possibly a dumb question. Is a 1/8 scale winch to much? Iamb lam pushing 1.9 tires beadlocks just got mil shafts fresh from the tower. Iam running a vxl setup with 3s lipos (yeh rig pops wheelies!) Yeah before the smart asses start start I know it probly wasn't the best idea but my 12 turn didn't do it for me. But yeah any input would help. Thanx guys

The body of the 1/8 scale is just plain to big. If you want more power than the 1/10 look at servo winches. Really the 1/10 is a good starter winch, I've ran mine over two years now.

Lots of us run 13.5 turn 3,300kv sensored motors, about the same power and speed as your VXL, just way smoother down low and we have dragbrake. You can run sensored motors off your ESC, but still won't have drag and instant reverse.

I just have to ask how's the driveline holding up with the 3s VXL?Is it stock?I've been contemplating some more power...

[indiana mudcat]

The rear shafts are about the only part of the driveline that will last long term, even on 2s. 3s just makes parts break faster. It takes a while to wear out the gears, lockers usually last until you get front shafts strong enough to hold (300's or VVD's). Honestly a 35t on 3s is gonna break the same parts, just not as fast, once your upgraded your good.

Another good consideration is that if you get a snatch block you effectively double your capacity or the other way of looking at it is that you half the work load on your winch. I like the 3racing winch. I've heard spotty things about the RC4WD winches. I know the 3racing one enough to recommend it.

If you get one, look into re-soldering it up to provide power to itself. It's much nicer than figuring out an external power source (another battery). You can basically splice into the wires coming from the control board for the receiver plug (white, red, black). You splice into red and black and jump them over to the red and black for the power input. Search on here, I'm sure someone has a nice write up.

About the snatch block, alot of people don't use them right. I am certified in High angle Rope rescue, and I know a thing or two about mechanical advantage. For a 2:1 pull advantage you need to run the winch line from the truck, to the tree (through a pulley), back to a pulley on the truck and back to the tree. This would give you a 2:1 with a change of direction. Alot of guys just snatch the tree and attach to the truck, and you've done nothing but change the direction off pull.

...But now we're getting a little sidetracked ;)

Do a search for "servo winch". You can hide the servo in behind the 3racing winch or just route the winch line through a fairlead. It's a little more expensive but a servo winch will be a lot more reliable and pull a bigger load.

High angle rope rescue doesn't change physics :P

Truck>block>truck is indeed 2:1 If you start 50 feet from the tree, you'll have to pull 100 feet of cable to cover the distance.

[pottymouth]

Oh! ...unless you're winching somebody ELSE's truck. My truck>block>your truck would be 1:1. A 50' pull would pull you 50'.

[Arctic Fire]

I'll find some examples to help explain :(

Truck -> snatch block -> truck is a 1:1 mechanical advantage... it's just a change of direction. Unless you count that the winch itself is a pulley, but that's getting tricky. It's a common misconception and even the winch companies get it wrong when explaining it. There are several advantages, the load is reduced because of the winds of the winch, but not halved.

like scenario 1 in this diagram.



Great examples of a 1:1.. note they mention that the load is reduced because of winds on the drum, not the pulley in the 1:1

And here is my example of what a true 2:1 would look like as you winch yourself.

Well I just put in mip shafts kept blowing my shafts outa the cvds the vxl is nice pop wheelies no problem on the stock 1.9s but I think I may have ground a gear in my front shaft ill let ya kno when I open it up :P

[arcanecrawler89]

Thanx guys yeh I know about the whole snatch block physics iam military and our m88 we use winches to pull power packs and wat not but my question was completely overlooked lol just tryin to find out if a 1/8 winch would get burned out or shorted out from bein hooked up to the 3s Lipo:P

[Arctic Fire]

Yeah.. we got pretty sidetracked. I would start with a RC4WD bulldog and if you need more, switch to a servo winch ;)

[toka100]

i wouldnt recommend the 3s lipo on the winch. it would handle it but not for long. the servo winch is your best bet. depending on the servo u use there wouldnt be any issues with voltage or weight. mine with out a snatch block can lift 25lbs.

[arcanecrawler89]

Yeh I thought about the servo winches just like the scale look of a winch a lot so I may try setting up a servo winch and run it thru a fuax winch or try running a seperate battery for the winch itself

[cguit]

3racing makes a winch that im pretty sure is identical to the rc4wd one except its not 70.00. i got one for 30.00 CaD
