I have an old X-RAY the T1r but I quit competition racing long time ago and now I’m converting this Raycer to a drift vehicle to master scale drifting skills.

Thanks Alex you are doing an incredible job, everyone can improve thanks to your explanations.

I found your videos by accident. So glad I did. Very informative. Easy to understand. Thank you for doing these.

Can't wait for the next video - keep them coming!! :D

Really really helpfull, looking forward to NeXT 👏

Verry felpfull info!

love these these are so helpful

ok so a little tip changing camber affects bumpsteer u literally lower the steering rack mounting point with going more negative camber i was searching information about setting up suspension because i have huge bump steer after i changed camber and after watching this whole video i understood what was going on i had 0 camber now i run -1.4 steering rod dropped about 1mm at first i waas worried because car act funny but i got a bit used to it now and it feels like driving rally car with all that bumpsteer

Thanks!

This is awesome, thanks so much Alex! The only question I still have is why would you want bump steer if it changes the steering during cornering or going over a bump?

Because it can improve the steering of the car.

For those who still read the comments. Bump steer in theory helps to fine tune Ackermann independently for inner and outer wheel as load shifts during a turn. To achieve the most lateral force available the wheels must steer to a point where the skid or slip outwards is at the optimum angle. This optimum slip angle depends on the load the tyre is experiencing and in the case of a turn the outer wheel having a higher load would require a greater slip angle than normal Ackermann would allow for (vice versa for the inner wheel). During braking both front suspension compresses causing a toe in effect which can help stabilise steering under braking. And under acceleration it has a toe out effect which can increase steering under acceleration out of the corner.

Hi. I wanted to know if when mounting the servo to a floating servo arm if the position in terms of as high up on the arm as possible or as low as possible. My reference is to the "ears" of the servo itself as there's some play due to the "ears" design when installing the screws, so I wanted to know if that made any true difference with this as the height of the servo horn will be mm in height difference. I asked because I've re-installed my servo a bit higher as I had a crash and now I'm seeing more clearance between the servo itself and the chassis. In your experience would this make any difference to how the steering responds from left to right? Or is this something that really doesn't make any difference?

It will make a difference if you raise or lower the servo for two reasons: 1. CG (if though minimally) 2. The angle of the steering link. Having the steering link straighter gives a more linear feel, and having it more angled will make the steering more progressive. You should avoid having the servo sitting too close to the chassis as this can affect the chassis flex. I usually try to mount it with at least a 1mm gap to the chassis plate.

The tool stand on the edge of table, did it ever fall by accident? Did you secure it with double side tape?

I do knock it over by accident sometimes. Lol. I didn't use tape, but probably should.

Was that behind the steering rack or in front of the steering rack?

Ackermann angle is adjusted by adding or removing shims from in between the steering links, and the steering rack.

@Alexander hagberg I know that this is for on road vehicles but does setting the akerman on off road vehicles follow the same principles

So basically if the outer wheel turns more or closer to the inner wheel it will have more steering..!!

why are you all running spools in the front axle and still consider something like ackermann? your wheels wont turn at different speeds due to the spool anyway? can't get an answer i'm pleased with, asked a lot of youtubers by now... :( the outer wheel will have higher speed than the inner wheel in a corner, but with a spool, that's not possible. Only thing i can think of, would be on these RC cars, the inner wheel have next to no traction or even maybe lifts of the ground a bit. Otherwise, no idea..

The spool makes the tires turn at the same speed - you're right. But the purpose of the Ackermann is not this. The Ackermann affects the relation between the steering angle between the inner and outer wheel, not the turning speed.

@@hagberg my man, ackermann is to compensate for the different turn radius, yes. But using a spool, makes the turning a little bit awkward in theory. One wheel would be dragging or spinning through a corner, depending on which wheel has the most traction. I know why the ackermanns exist, i know what it is. But my question is not about ackermanns, it's about the spool. Why a spool? It makes some sense if the inner wheel is in the air during a sharp corner.. During a race, i can see this happening. But anywhere else, and while drifting, i cannot see a spool being superior to a differential.

@@xibidit I am pretty certain that the inner wheel picks up during cornering, especially on higher grip conditions. A spool also has the benefit of less rotating weight (it's a lot lighter than a diff) which improves acceleration.
