Default Bevel diffs

I just bought all the parts o build a bevel diff for my RB5.
UM610, Um605, UM611, UM613, UM612.

Is there anywhere that gives detailed assembly instructions, what diff oils to use, etc?

Which way the diff goes in transmission.

Thanks.

the wider rf blocks make the car rotate much better from the center of the corner out they also add to the stability due to a wider track width. most tracks i run at are medium to low traction and i still think the wide blocks are the way to go. just my .02 cents.

Don't forget the orings, OR0145 or something.
Nothing special except maybe not overtighten the case.
People tend to run 1000 to 3000.

Heard Kyosho have steel gears available for the 1/10th onroad cars and they fit.


The car is really awesome, ran it only as a Mid motor.
Very happy, they did a great job on a lot of things.

Hi Guys,

Can someone kind enough to tell me what is the different in rear motor and mid motor? I see in the manual they have two options. I will be going with the stock ie rear motor but just interested to know what is the different between the two and are all running rear or mid motor? What conditions should we run mid motor?

Also I'm looking at chaning the rear suspension to the aluminium one. But there is four options. Which one should I get? Or I need to get all 4 of them?


1) KYOUMW515GM - Kyosho Aluminum Wide Rear Outer Suspension Holder (Gunmetal)
2) KYOUMW514GM - Kyosho Aluminum Wide Rear Inner Suspension Holder (Gunmetal)
3) KYOUMW511GM - Kyosho Aluminum Rear Suspension Holder (RF) (Gunmetal)
4) KYOUMW512GM - Kyosho Aluminum Rear Suspension Holder (RR) (Gunmetal)

Cheers guys

Mid Motor is going to be used on super duper mega holy shit high grip. Most UK tracks, or those that use astroturf. If you run on dirt, unless your track is mega grip, I would just run the rear motor.

The mid motor is a lot more aggressive with steering, at the expense of rear grip.

I see. Thanks mate. That does not sound like something I need. Rear it is. Cheers.
