XX4 Ackerman??

[bretts]

I know this is a bit of a noob XX4 question, but.....

Which is the best setting for the ackerman inside or outside?

I've looked at a few cars and setups and both are used. :confused:

Any help will be much appreciated.

Cheers

Brett

we use the outside hole all the time

[Northy]

Use the one that makes it steer properly, not the one that makes it go:

Push, push, push, push, push, hook!

If there is one that is.....

Which ones that? :confused:

sorry guys, at least from what iv'e been told and what i've read, it doesn't look like there is any ackerman adjustment on the xx4(from looking at Jimmy's review car) The only adjustment there is different holes for the steering drag link. In this case, the inside hole would provide more throw before the steering assembly would hit the Diff adjustment plates. If you run the inside hole, you will have to shorten the turnbuckles, and there may not be room for that. I think that The car is fine on the outside hole, and doesn't need any more steering.

cant remember which way round it is, but one option gives the car a more positive feel going into the corner, the other gives more on-power steering.

Lazerboy - you really are genius! will you be my crew cheif for 2008? :eh?:

What they are all saying is that the Losi XX4 steering setup gives a greater difference in ackerman between the two settings compared with the centre link type of adjustment in your picture, the complete opposite of your statement.
Whoever is talking to you and whatever you are reading don't know what they are talking about.

Generally less ackerman (the standard setup) gives more aggressive steering and better steering into the corner, but can lead to sudden oversteer when you let off the power in the corner and the outer tyre loads up.

More ackerman (the inner holes) gives less initial turn in but is more consistent through the corner. Also gives better steering at low speed (but who wants to go slow:D)

for a complete explanation on the effects of ackerman steering in a model car.

[lazerboy]

Rc car action isn't wrong, i just didn't think about the fact that if the link was moved to the inside holes, the steering link pivots would move back ever so slightly, and this would have an exponential effect, and they would move even farther back as the wheels turned more.
