RE: 4 wheel steering??
my friend did it to his LST and took it right back off it was to hard to steer at any speed it was really only good for doing bad ass donuts but that is just my 2 cents

RB Innovations makes a 4 wheel steering kit for the Savage if you are looking for one. [link=http://rbinnovations.com/catalog/product_info.php/products_id/148?osCsid=bbbf08fbc1ab4b67b67c5cfe0dcd85c4]4 WHEEL STEERING[/link]This the link to go strait to it so that you can see exactly how it works and cost. I'd say that you can do it cheaper your self but I don't know, but it don't look too complicated by looking. I hope this helps you out, just let us know.

I also know somebody who did this to his LST and he complains about it all the time. He said it is impossible to control at higher speeds but is nice when going slower.
I dont know if it would work but would the front diff/control arm/bulhead assembly be able to mount on the rear after redrilling the TVPs. It seems like it would work. Also, you would have to wire the second servo into the same channel.

The reason it is hard to control at high speeds is a true 4WS has the wheels turn in the opposite direction at low speeds and the same direction at high speeds ('crabbing'). Physics mandate that it is done this way, so what is really needed to do it right is some sort of electronic control. I have actually been thinking about developing one, but I'm not sure how practical it would be, because of cost and a possibly complicated set-up.

?, if you put the reverse steering servo on a channel were you can reverse the direction, when you get to a certain speed you could hit the switch manually, changing the direction of the servo to make the wheels turn the same way, just a thought.

I wonder if any high end radios have a conditional mixing, or something to that effect so you could do it automatically.

That's actually a pretty good idea. Good thinking.

Cabbie over at Sav Central has a good idea (above link) that the rear steering will only start to kick in when the front wheels go over half way.

Yeah, I think what Cabbie is doing may very well work. Generally you don't turn extreme angles unless you are going slower, though if you did turn sharply to avoid something at high speed I think it would roll over or doughnut. I'm interested to see how it turns out for him. Seems like there is interest in this though, and I have been considering an electronic controller. Perhaps I could actually make money instead of spending it for once BTW- he's a great fabricator- very jealous.

I was just watching monster jam freestyle, and the four-wheel steering they use (on the 1:1 trucks) is completely independent of the front wheels, and is controlled by a separate switch in the truck. I figure i would use three buttons - one to move the wheels left, one to move them right, and one to centre the wheels. this would take just the right transmitter tho, but i think it's possible.

I saw a video with one jumping with 4 wheel steering and it broke after the 3rd jump. Personally, I would invest your money in soemthing else.
