After doing weeks of research on the RB One I finally purchased 3 rollers.
1 for me, 1 for my son and 1 as a spare/donor car. We will use them to race at our local track.
During my searches its not hard to realise that there isn't much info about regarding the RB One.

This thread is my attempt to try to gather all the information together in one place to help others and remind myself.

I'll skip all the advertising and promo stuff as thats a job for RB Products - see what they've done here http://www.rbproduct....esentation_INT

Any RB One owners out there PLEASE CONTRIBUTE anything you can.

Thanks especially to o.j. and Catch22 who have provided me with most of the info so far.

Problems

Problems I've read about so far...

1. The rear diff crown gear losing teeth. This was caused by the wrong amount of shims being used coming from the factory. Reshim to make it a less tight will solve the problem.

2. The front dogbones don't take much abuse. Change front dogbones to losi 2.0 ones as they are a perfect fit.

3. Spares seem to be hard to get. This problem has been exasperated in the past week or so with the current distributor (CML Distribution) deciding not to keep RB Products any longer. No doubt another distributor will take RB Products on for the UK in the future, but in the interim that could be an issue.



Alternatives

Springs
With no RB alternatives for shock springs available for the RB One we have to look to other manufacturers for compatible ones.
So far what I have believe is
Kyosho springs fit
RC8T springs fit
DNX408 springs fit
xray 808 springs fit
Hong Nor Front truggy springs fit

Shocks
I think Hotbodies D8T and xray 808 rear shocks fit and the caster truggy shocks fit too
It seems you can easily switch the rear shocks to the front side of the tower and route the rear stabilizer under the rear torque bar. Anyone know what effect this would have on the car?

Body Shell
In the absence of being able to get another RB One Shell you can use a JConcepts Losi Punisher shell . It fits with only very minor trimming .
From what I was told you just need to cut the hole for the engine head a little further back, adjust the location of the mounting holes as they are in a slightly different place and also shave a wee bit off at the front where it wraps around the front of the buggy. After that it ends up a PERFECT fit . It hugs the side gaurds really well and covers all the areas to keep dirt out .
On the RB One, the throttle linkage will stop a lot of shells fitting, but the punisher shell has high side pods and fits super nice .

Other stuff
I have also been told that the RB One has some similarities to the Durango. I don't know this for sure as I have no experience of a Durango. Maybe somebody could confirm?




Setups

The brake setup looks the best ive seen with the adjustable brake bar for adjusting brake bias, Looks like an easy layout for maintenance and the dust boot covers on all the drives are a nice touch . 4 screws to remove the spur gear guard and centre diff is out in your hand (no messing with linkages) Also radio tray looks very good .
Happy starting point for diffs is 5f 5c 3r, shocks 35wt all round. It might help to run 1.4 holes in the pistons on the front and find harder springs for the rear (eg. Purple Xray 808 Springs).  (See alternatives above)
Dave Crompton suggested that all 4 shocks should have one of the rubber o rings removed to free up the action.  This seemed to make a big positive difference to the damping.

CML have removed Dave Cromptons setup sheets from their website, but I took a copy before they did.  I would happily email a copy of them to whoever wants one.
Heres another setup I found on the net which may be of use:


Catch22 uploaded a video of his car going around CSOR

Bearings
Hubs
RB One uses the same bearings on the hubs as the Losi 2.0 (and the Agama too).
You will need the equivalents to Losi LOSA6953 12.7x19.07x4mm (1/2"x 3/4" x 5/32") and LOSA6945 8x14x4mm.

The hub bearings are not the flanged bearings shown in RB's exploded diagram of the One.

Diffs
The flanged bearings mentioned above are only used on the centre diff. They are the same as the LOSA6948 (8x14x4mm).
The front and rear diffs have the standard 8x16x5mm bearings from several 1/8th scale buggies, like the Hyper 7 (Part#84076) or Agama (Part#AGM53) etc. These bearings aren't on a Losi.

Servo Saver/Steering assembly
Again the bearings can be found fitted on the same location on a Losi. The ones you're looking for this time are LOSA6946 6x10x3mm.

Clutchbell
I'll include it for completeness but its just a standard clutch bearing (5x10x4mm) Losi equivalent LOSA6949


Industry Standard codes of bearings:
LOSA6953 = R1212-2RS
LOSA6945 = MR148-2RS
LOSA6948 = MF148-2RS
H84076 = MR688-2RS
LOSA6946 = MR106-2RS
LOSA6949 = MR105-2RS

Complete rebuild would require:
8 * LOSA6953
4 * LOSA6945
2 * LOSA6948
4 * H84076
3 * LOSA6946
2 * LOSA6949

[Rick1486]

Does anyone know where we can get the replacement pre-painted bodies from?

Been running mine today and have noticed that the front body post may be a tad low as when turning left the allen head on the steering bar is catching on the body (may need to trim the bodyshell as can't seem to raise the body post unless someone knows if this is possible). Also, the body paint is rubbing off on the side runners at the front and back corners - seems to be such a tight fit.

Or are there any other body shells which will fit this and where can we get them from?

Cheers
Rick
