Why no emulsion on 1/10th scale?
 

As Tekno and other 1/8th scales start moving towards emulsion style shock builds as their default setup why don't the 1/10th scale cars run emulsion shocks?

I'm sure it's a dumb question just couldn't find any answers after searching.

Most do.

Lots of 1/10th scale shocks are emulsion. Your B6 and T5M are.

Kyosho shocks also emulsion.

I must be getting confused between running a bladder vs. emulsion and I guess what i'm asking is more along the lines of...

Why on the Tekno shock build they want you to leave all the bubbles in the oil, vigorously work the piston up and down 30 times, then bleed and lock off?

Seems like on all the 1/10th scale stuff it's all about eliminating air in the shock?

Here ya go, have a read. It might help with your air in the shock question.

Iirc they want you to move the shock up and down to release any air bubbles then you let the shock sit upright for a few minutes so the bubbles can escape before you seal things up

Pretty much all 1/10th scale shocks are emulsion.

So why does Tekno want air in the shocks and all 1/10th scale want no air in at all?

I'm not sure where you are reading that because the manual states you need to allow the shock to rest upright so that the air can escape before you fill and seal the shock.

Emulsion means a mixture of air and oil. The 1/10 scale emulsion will have air in them. It's not always described well, and Tekno adds the second bleed step that most are not familiar with.

The o-rings leak air into the shock and there is nothing to control exactly how much, except constant maintenance.

EB48.4 Manual has a different procedure as the box stock setup: https://youtu.be/cu9rdSr8gvw?t=41m23s

I think it's just the wording that causes confusion. In the 48.4 manual they want you to do steps one and two on each shock before moving onto step three. Allowing each shock to sit upright as you fill the other shocks. And by the time you have filled the fourth shock, the excess air bubbles will have escaped and allow you to proceed onto step three, starting with the first shock you filled. I believe the air required for emulsion would come from the volume of the cap since you can't exactly completely fill it with oil. But that's just what I take from the manual. I still go for vented.

I get you. Just weird that they specifically want you to mix the oil and water together almost like salad dressing... never seen that in any other shock package.

From the videos on Tekno's Youtube channel they say that running emulsion with the oil/air mix like this is providing more consistent dampening over longer runs.
