hydro steer
 
I have been thinking about this for a while now. how can I make a hydro steer setup.

I was thinking taking a shock and putting preassure fittings on eather side and filling the holes on the valve in the shocks and connecting it to another shock via gas lines. a servo will move one shock mounted to the chassis.

I was also thinking that some company (maybe Tamiya) made rc tractors which I think had hydrolic cylinders on it.

could any of that work and would it be worth it?

where did you get those hydrolics? or did you make them and how?

rockcrawler_101 09-14-2005 11:52 PM

Yeah and he spent over 800 bucks on it! heck i didnt even spend that much on my full hydro on my 1/1

I followed the link to the pics and vid, but it was all red x's and I couldn't d/l the vid...


I'd like to see this!!

JasonInAugusta 09-28-2005 01:06 PM

rerock, I'll have to upload some pics and stuff later tonight.

I deleted a ton of stuff off the server, some of it by accident.

Snakeman, that video is of a hydro alright...a Miss LLumar Hydroplane. :lol:

rockcrawler 101, Yeah, I know what you mean. My 36" Iroks were $879 mounted, balanced, and shipped to my door. A little pile of aluminum or a big ol' set of tires...basically the same price.

BUT...this is a true scale hydraulic steering system. It's a one of a kind. ;)

rerock 09-28-2005 01:38 PM

That'd be sweet! I gotta see this.

jeepster 09-28-2005 02:32 PM

yes I to am very interested to see this set up, I would love to run that on my crawler.

I forgot...there's actually a page on my website..

Just uploaded a few images to my server as well...

The wiring/plumbing diagram I made...I ditched the skysport and used an Airtronics VG6000.

JasonInAugusta 09-28-2005 10:17 PM

Thanks guys.

Chris, I literally get hours of runtime on this truck. With a 3300 pack and a reduction ratio of 150:1 the motor that drives the truck draws very little current. It's slow, but I wanted it to move slow. The hydraulics pull very little current as well, but they're powered by a seperate lithium-polymer pack.

Geez Jason ... i think i was just looking at build pics or something in another thread and thought those tubes were for aesthetics purposes, im in awe they are functional.

rerock 09-29-2005 07:04 AM

Wow man, that's absolutely incredible! I think that thing goes into the top 20 of the coolest things I've ever laid my eyes on.


Now if only I could remember the other 19...:mrgreen:

jeepster 09-29-2005 08:51 AM

snakeman 09-29-2005 11:50 PM
