Need help finding Hydraulics

[jh1985]

I want to make a 1/10 or 1/6th wrecker Like the one i drive from work.


Any ways I want to have a boom Raise up and down and extend. Thats 3 rams there and a wheel lift that goes up, down, in, out, left, and right. Thats 3 more
So i need 6 total. I could do it with 4 but it wouldnt be exactly right. But im willing to comprimise.
I want hydraulics if possible maybe a kit.
It could be something that looks like hydraulics but functions the same. and ideas or website where i can buy kits and parts.

Thanks. It might be cheeper to canabeliz a rc construction

And body know any thing about screw drives?

[Johnnysplits]

Yeah, looking through that site would give anyone sticker shock.

Well I did research all day. I found a way to do it with air retract cylinders with a hydraulic conversion from hobby king. But i thats still 250 to 300.
I had a great idea playing with my rc4wd winch. I can use extra winch motors and attach a long bolt to it and make my own screw type lifts.
It wont cost much. Then i will make fake ones for looks or wrap the winch ones i make.

I think this project would be much easier and cheaper if you engineered it using servos. You could control them with a multi channel radio. You wouldn't have to use 1/10 scale servos either.

Air retracts won't hold much as far as positioning goes its either in or out with a lock feature, and their not very controllable as far as speed either. This subject has been touched on multiple times on a few forums. If your not going for actual operation use as much as looks these could work.

Check out Scale 4x4 R/C - Home or www.rcttuckandconstruction.com for tons of info on hydro and screw drives.

It's not cheap by any means but there's a few company's that have conversion kits that use hydraulic rams w coolant instead of hydraulic fluid and their cheaper but again not as reliable. --- mangon rc does a few kits for construction but could be easily converted for your build.

There's also firgelli actuators which are electric rams that can run direct off a rx like a servo these have been used multiple times with great results and I have used them on a few builds as well. I'm actually gathering parts for a build now and will have 8 of these rams being used throughout it.
