88 spur / 50 pinion X 2-IR = 3.52

Or you could download "RC Gears" for your Android phone and let it do all the calculations for you

Hey Guys,

Has anyone measured the arm roll centres in comparision with other manufactures.

i.e. Medium high is equal to 1.5mm under TCX toe blocks

It would be great to get an understanding on this?

cheers

Are those new front harder UJs? I am searching for something stronger than photon's alum UJ but not the steel ones. Haha. Any good 3rd party recommendations?

Why not the steel ones?

Because if you are really that concerned about rotating mass, they make no discernible difference. But they are very reliable and inexpensive.

Ok sure, will try them. Anyways, have any of you guys tried fitting Spec-R C.V. Universal Swing Shaft on your TOPs? Any of those fits?

I know that Jason Schreffler and Larry Fairtrace have run them. I believe that it requires widening the hole in the c-hub to allow for the larger diameter driveshaft. May also require a different bearing, but I'm not positive.

I can tell you that a MH block places the centre of the suspension shaft is 7.5mm above the bottom of the chassis plate (2.5mm chassis).

As I'm sure you already know there is 0.5mm difference between each insert position.

I can't tell you what the equivalent setting on a TCX is. For comparison, on a TOP Scythe, 0mm under the blocks gives a 7.5mm pin centre.

By the way, the lower arms on the Photon are the same length as the TCX (and Pro4 and Cyclone), the front c-hubs have the same geometry (although the knuckles have 1mm wider offset), and the rear hubs are the same height if you add a 2mm spacer, although they upper link position is 1mm outboard. (by my measurements )

Almost all modern TC's are very close to Yokomo's MR4 TC SP design dimensions. The Tc3 was almost indentical to the MR4 TC (i know, i owned both). Ideally they are all clones, with exception to the last Losi offering.

Whip out your micrometers... spend a few hours comparing parts. You will be surprised.
