Is this normal?

[KennethXJ]

I am a noob. So bare with me...
I just got this RC and noticed when I turn either one of the outside tire will turn Really hard. Both wheels do it just only when it is on the outside of the turn Look at pics.
I was told it has VP high steer knuckles, HR one (not sure what "HR one" is)

That is your steering ackerman which is WAYY too much. Back off your endpoints for your servo some.

How bout a pic with ur wheels straight? And maybe one with a pic of ur knuckles?

I don't think the epa has much to do with what ur tie rod and knuckles are doing. Backing off ur epa will only stop the outside from steering in so much, which also stops ur inside tire from steering as well..

It looks like you have too much toe in. So you can simple back off the link ends on ur tie rod a touch and it will stop ur outside tire from turning in so much and will allow ur inside to steer more.

Sorry for long response, I was out of town. Here are the pics you asked for.
I have tried two different tie rod lengths

It looks good from straight on.. hmm.. I still say run it with some toe out.. make you and the steering much happier.

Is it due to flex in the plastic C-Hubs? Mine does this as the servo is too strong....and I haven't set end points.

the ackerman is reversed. ive seen 90% of Axial axles do it. I can see on your knuckles you have two mounting points. move the draglink to the holes closer to the axle. it will decrease the difference in steering angle between the two tires.

my wraith does it, but only just noticable.

the problem comes from when the drag link is shorter than the distance between the kingpins. so if it was behind the axle, as it is, would be perfect, coz the inner wheel would steer more and thats the way it should be. so for now, as i said, just try it on the holes closer to the axle, and also run some toe out, as Winner said. both will help with steering properly.

Hope that helps.

Guys, I really appreciate the advice! I will try all the above and I am looking for some metal chubs also.

You might try swapping the chubs, side-to-side, and see if it makes any difference.

not attacking you, but may i ask why you think that might work? swapping Chubs side to side will only change the castor, not the Ackerman.

OP needs new knuckles. they look like the VP hi-steer knuckles, which i think are optimised for BTA (behind the axle) steering, in which case would be IDEAL with it steering the way it is.

infact, KennethXJ might consider mounting the steering system behind the axle, it will work much better that way without having to replace parts.

just reverse the servo horn and knuckles. done.

edit: if it fits.. lol

I hate it when people say your hubs are backward. They are the same. The issue i ran into was it steered harder one way than the other so i adjusted my link off the horn ive reset the horn and ive played with the steering link for tow. And adjusted steering trim on the receiver.

Totally normal for stock steering geometry. Vanquish also has some zero ackerman knuckles which should eliminate the problem.. some have reported clearance issues with stock offset tires though so your results may vary. In any case the steering as is wont hurt anything it will just cause a bit of tire scrub and increase your turning radius.
