Re: Wraith 1.9.2
 

Is it better for the truck to be lower, say with the lower links level

It kinda depends on the terrain you run on, but yeah, it is.

Re: Wraith 1.9.2
 

Good deal. What is the best shock angle for crawling on rocks, obstacles and such?

Re: Wraith 1.9.2
 

I can't tell you that. There is no universal "best" setting. There's "pretty good" and "in the ballpark" until you take the time to tune it yourself

Re: Wraith 1.9.2
 

To additionally clarify, shock angle isn't a setting that's right, wrong, best or worst, as Duuuuuuuude says it's a tuning tool,

My half baked learning says the more angled from the travel path of the axle through the suspension cycle the softer the effective spring rate.

If spring A is too soft & spring B too heavy with the shock stood perpendicular to travel, laying the shock over with spring B can tune out some of it's rate. May then go to being too soft but that's sometimes how it goes.


The other thing that can be achieved is where the shock is angled to travel at the start at full extension giving a softer rate but at a point through the travel the change in angles brings the shock closer to perp to the travel, bringing the full rate of the spring back on to try limit bottoming out the shock. (think of IFS on buggys & shock position versus arm swing)


This however is not a limitless adjustment, at some point the shock will be so laid down as to do virtually nothing other than rotate around it's mount.

Softer, and progressively so as the suspension compresses.

I'm trying to picture this in my head and it's not happening.

Re: Wraith 1.9.2
 

It was primarily from picturing in my head I got to that so I could be mistaken.

Edit; tinkered with a drawing
I wouldn't go so far as to call it proof but it did work as I pictured in my head,
though not as entirely feasibly as I imagined & it's dubious as to whether it would achieve what I thought it would.

Based around basic SCX10 style geometry using a 90mm shock with 25mm travel it can be seen where the shock is lees than perp to the lower link & arc of travel at full extension but as it reaches full compression the shock is now perp to the link & travel.
Now I'll quickly agree it's highly dubious that the 10deg incline of the shock at full extension does anything to change the spring rate noticeably.

Has turned out to be more of a thought exercise than anything truly practical.

Re: Wraith 1.9.2
 

Yeah it'd spend so little time in transition that it wouldn't be noticable. Always nice to see somebody doing the math though. :ror:

Re: Wraith 1.9.2
 

Can’t wait for those link risers, I imagine they will make quite a difference!

Re: Wraith 1.9.2
 

Don't think that these are magic bullets, because they are not. They just give you options for tuning. On a bone stock rig the difference is subtle, but more apparent on a modded rig.

Tuning out torque twist and increasing capability is a method with several steps. Adjusting your links is one of those steps.

Re: Wraith 1.9.2
 

Ah! Fair enough! On my old wraith / bomber when I switched to the link risers, it made a noticeable difference. It was quite modified already at that point, so that makes sense.

Re: Wraith 1.9.2
 

When I put those up for sale I did a before/after video as a promotional tool. It was a little underwhelming. You feel it more than you see it.

Re: Wraith 1.9.2
 

I’m definitely looking for anything to keep the front end of this new truck closer to the rock. I’ll keep trying to tune everything better, too!

Re: Wraith 1.9.2
 

So I made a thing today.

Re: Wraith 1.9.2
 

Beautiful. Make 3 more things and you'll be on to something.

Re: Wraith 1.9.2
 

I only have enough material for one more thing. That's ok though, this was only a test.

Re: Wraith 1.9.2
 

I'd say that you've passed the test.

Re: Wraith 1.9.2
 

I miss DCW!

Re: Wraith 1.9.2
 

Them are purty. "thumbsup"

Re: Wraith 1.9.2
 

:shock: WOW!!!

that's all im gonna say at risk of turning this into the IFS thread... ;-)

so yeah... WOW!!!:shock:
