4 wheel steer with 2 channel radio?
 

I am trying to get 4 wheel steer on my axial. I have the kit so my so my axels are the same front and back. My problem is the servos. How do I get the rear one to turn the opposite direction? Is there just some wires that I can swap around? Both servos are the same brand.
THANKS

i think they make a servo reverser you could buy one of those and a y-harness and run those, i think?

One of these should do the trick:

you have 2 options.
1) this is the easy way. get a servo reversing y harness.
2) open the servo up and swap the wires on the motor and the outside wires on the potentiometer. that will make the servo work in reverse.

You could also run a Futaba servo on one end and a Hitec on the other. Most cases I found the 2 brands turn opposite each other.

Another option if you have the room, or a way to mount it, is to turn the servo horn 180* so it pulls opposite.

Thanks for the replys. I am gona turn the servo horn upside down to see how I like the 4ws. And if I do then I will have to do something else.

flip the arm so it is faceing up

have you tried turning the servo over and connecting to the other knuckle

did it work i wanna set up a 4ws with my emaxx crawler but i have a 4 1/2 ch trx 2.4 radio so its not hard i can just hook them to different channels

I Promise you are going to Love 4ws...."thumbsup"

I used a reversing harness on the Maxx crawler I used to have.

Rear steer rocks! Monster GT tires are pretty sweet to :)

Get a servo reverser, they are like $8 at your LHS or cheaper online. With the harness you can control how much throw the rear servo has. It's really the only way you will have any endpoints with a 2ch;-)

for now i just filped the servo arm. I do love the 4ws!! She turns good now! But i do not like the way it looks. So i am gona get a reversing "Y" harness. Or try for a TQ3. But that will have to wait till I find alil money!!!!

How about a punk RC controller

it's quite expensive no ? and little complicated to install IMO would like something simple only 4WS no crab or dig ;)

Not to expensive think I picked it for $40 about 9 years ago. Super easy to install just about five min setup time.

be better off putting that money towards a radio that will have it included in the programming
