    So in laymans terms Ackerman is the concept of the inner wheel turning at a more sever angle and pulling the outer tire through the corner?

    The inner tire may in conditions pull the outside tire through a turn but ackerman is more of giving the inside tire a tighter arc to follow as its following a smaller circle.

    Ackerman will serve you best if both tires follow the proper size circle they are on and you are hammering the brakes and sending a lot of weight to the front end in a corner. If the tires are not following the correct paths the front end will try to fight itself making for poor handling.

    RcTek - Radio Controlled Model Car Handling Main Section Page

    That will show you more and better about how the inner tire needs to be turned more.

    ALL the aspects of ackerman will take some time to read and understand. Some on road guys use negative and other ackerman concepts (shown at the link above) as they feel it helps the steering on pavement in certain racing conditions.

    The link above is on road and RC but does translate to long travel buggies off road in most aspects.

    Its the best site I have seen to show and demonstrate ackerman.

    Now that NOBAMA has PROVEN he is the absolute WORST president in the history of history Jimmy Carter can thank him for stealing the dunce crown.

    Ok, i think im beginning to get it. I checked out that web site, and read them all, the droop part was anti climactic. Correct me if im wrong, But you effect Ackerman by the angle at which the tierod attaches to the spindle.

    Sounds like you got the basic idea on ackerman yup.

    Droop is very important in offroading. I will need to go see the droop part on that site again.

    So basically what you want is a set up that as the inner tire turns, the angle and "speed" at which it turns raises, and the outer wheel lessens or stays constant as it travels through it's turning arc. Sounds like Geometry class all over again.

    Actually it IS geometry all over again. Some people even like negative ackerman! (Its in those links above so you can see what it is and how it works)

    Heres the FUN part. Ackerman is the easy one! If your building from scratch. Using other parts (IE> quad parts you gotta plan around the already built parts carefulley if you want something that does not handle like a turd! Every little difference makes a BIG differance and some might affect your setup in BAD ways.

    DON"T FORGET!!

    Between camber and caster and scrub radius and rake and side scrub (different from scrub radius (quite different yet sorta similiar!)) AND bumpsteer!

    Toss in rising rate camber and if you REALLY wanna get fancy add in anti squat or antidive.
