I liked it ...it felt a little numb on a new layout on crc black carpet..but when the traction comes up it will be dialed...i did not have to glue sidewalls on jacos at all..never even once danger ofvtraction rolling

You might be right (at least I hope so). I'll have to look at it closer and actually measure the step with my digital caliper to see if its accounting for the wheel size.

Here's a good tutorial on calculating droop using the measurement over the axles. As you can see from the formula, different tire sizes results in different measurement over the axle to achieve the same droop setting.

From the article:

• Remove wheels and tyres
• Place flat on setup board, and measure to top of axles.
• Then using; [((Td/2) + 2) - Ha] - Rh = Droop (in mm)

Where Td = Tire diameter, Ha = height to top of axle, Rh = Ride Height

Doing the maff it works out

MR33 Gage

Wheel Diameter = 34.8
Gage height 25.0 = 17.6 actual

(WD/2) + GHa = 35

35- 10 droop block = 25

Caster gauges are out of stock everywhere. Does anyone know if the aerox digital or some other brand work.

You can try raising the roll center by 0.25-0.5mm under the front and rear arms on a steel chassis to get quicker reaction and remove the numbness out. I found raising it be 0.5 gives the same reaction as aluminum but with more stability and consistency

I just realized there is a newer version of the manual. The cover page is calling it Ver-03. (http://www.mugenseiki.co.jp/mugen/do...006_130925.pdf). I had not seen it before, so I thought I'd mention it.

Changes regarding:
- Shock X-rings
- Spur gear installation
- Belt tension
- Part updates (for turnbuckles at least)
- Safety and operation page.

Previous/older version: https://site.petitrc.com/reglages/mu...TC3_Manual.pdf (150425)

What's different about the shock X rings?

Same part, just in the treatment. We were originally told to soak them for 2-3 hours, but now there is the caution to NOT leave them longer than 2-3 hours.

To help the team out, here are the highlights:

Ensure you have a 0.5 mm space behind the spur gear. If you are using a wide spur, you may need to apply a spacer as outlined. Also, there are updated gear ratios*.

Initial heights of the belt tensioners are provided (3mm front/4.5mm rear)

Guidance is also provided regarding the excentric [sic] (ha) inserts. Specifically, recommendations for settings when using 80t and 90t spurs are given along with a note that eccentric inserts are set first and then the tensioner bearings are used to fine tune.

The safety in operations page reminds us how to turn things on and off, what to do if the car doesn't move, and how not to kill ourselves. Good lookin' out, Mugen. Seriously.


*I think I previously heard that there was a new motor mount, and maybe the gear ratios relate to the use with that motor mount. I'm not too sure about that.

I guess I can't see the differences since you posted the same link twice.

Found a copy of the new manual http://www.mugenseiki.co.jp/mugen/do...006_130925.pdf

There is a new motor mount, the new part number is mentioned. A2709-B vs A2709.

My bad, I had the wrong link in there. Yep, that's the latest version. Thanks.

I guess newer kits are coming with the new mount and turnbuckles?

BTW your edit only changed the display text and not the clickable address part of the link.
