4 wheel steering.

[>BD]

I want to use 4 wheel steering for my next build but I want the servos to work together and not be independent. Is there any wire adapter that I could use?

You use a servo splitter cable

2 servos do the same thing from 1 port on a receiver

Thanks.

You would loose many of the advantages of 4 wheel steering though.

I want something where all 4 wheels can turn at once because clod Buster axles don't have a good steering radius and I just want to improve the radius. Is it good for just that?

I don't know. I have never been around a 4 wheel steer vehicle. Most of the 4 wheel steer vehicles I have watched used crab steer to get to a particular place like to deploy a crane.

The internet says it does decrease turning radius

I just want it to make tighter turns and that is it.

Four wheel steering will definitely give you much tighter turning radius. Driving with it is very tricky, and you need to be able to adjust it. Too much rear steer will wind up with you having a lot of serpentine tracking. You can achieve that either mechanically on the linkage and what hole it uses on the servo arm, or ideally with a splitter that has a potentiometer on the lead that goes to the rear steer servo.

I can say that once you do get that ratio of front to rear steer right, the advantage you get in steering, especially on a tight, scale MT race course is significant.

Well it's gonna be a rock crawler that just goes over large piles of rocks slowly.

You don't always want them to work together, it will screw you. When you are at certain angles and you turn you rear wheels things happen you don't want to happen. I have mine set up on their own three position switch.

I just made it so it has a bigger radius because the ClodBuster axles have a terrible steering radius. I doubt it'll do much harm.

Trust me, it will. What happens is when you are set on something or at a steep angle. When you turn you back wheels and weight is sitting on them your weight shifts instantly. It can knock you over. I would rather stick with two wheel steer if I couldn't control my rear steer.

Rear steer at the wrong time will make you very unstable.

Yet the transmitter I was gonna get for this has a 3 position switch so I think I'm just going to use that.

Try it different ways, no reason not to. Right now mine is set up on a it own 3 position switch, I have the Spektrum DX5 rugged. It has different ways I can set mine up.
