Ultima RB5 Setups
 

Sticky thread for posting RB5 setups :)

RB5 Stock
 

I would like to get this thread started, here is a jpeg of the box stock setup. This is a low res scan. I also scanned in a blank setup sheet for those who would like it. Maybe it will help get some setups out... who knows.

Sorry guys but I dont have a set up for you yet but I would like to say I had a good day at Bury Metro yesterday. I won. Qualified second behind Danny Mcgoo and I thought that was good. I did stuggle from the wet as it was pretty much the same as everybody elses( crap ). When it started to get a bit dryer then I started to worry. I then got the B4 manual out and started to change a few things. I do think the shock towers from Atomic are a must and also some weight in the front. The car held up very well and I still think it needs work. I feel the pistons are still wrong but thats for testing. I am geting a race report together for Jimmy so you will all have to wait for it.

Atomic Carbon shock towers?
 

Hello,

could anyone give me a link or an url where I can buy the Atomic Carbon shock towers for the RB5?

Thak you very much,

Chris

they aren't officially produced yet, but Jonathan has a template to make them as an adhoc item. If there is enough interest in them he will hopefully "mass" produce them as a stock item so they will be slightly cheaper.

Below is a link to my RB5 setup from todays 2007 Qld (Australia) Championships.

Finished 3rd - and very happy with the car.

Hello,

how did you manage to fill in the sheet on your computer?
I just get pdf-files I can't fill in anything.

Regards, Chris

You need to download an editable blank set-up sheet. I have made a few for different cars on my website, but the one I used for the RB5 Ultima was made by Alexander Mach - which he graciously allowed me to host on my site.

You can download it here: http://web.aanet.com.au/fir/bender/M..._blank_rb5.pdf

You can then fill it out and print it - or store it as a PDF file if you have a virtual PDF postscript printer.

To do that you need to install Ghostscript from this link:
http://mirror.cs.wisc.edu/pub/mirror...3/gs853w32.exe

and then the free PDF Fill tools from this link:

My base set-up from Coventry on a very grippy day. ......

Often go to the silver #70 spring on the front but otherwise no change much now....

4 mm under the rear inner ballstud, surely that is almost falling out ?

The stock ball stud has 10mm of thread, as do the Yokomo parts I have replaced them with (as they have a 2mm hex to aid quick changes). That means there is 6mm still in the mounting boss, which is fine.

roger put up a picture of those yokomo thingies =)
changing the inner ballstuds for rear upper arms are :thumbdown::mad:

The part numbers you are looking for are

ZC-206MH 6mm thread
ZC-206LH 10mm thread

You will need to use US sized ball cups ...... I have the Losi whites on my car

I am shocking with a camera ..... trust me you will only be more confused if I post one of my calassic fuzzy thumb pictures!!!!!!

i got some black rpm 4-40 cups laying around :D
are those kind of ball studs with a hex in the top of the ball?

Yes mate ......... only reason for fitting them as the K' ball studs are good other than that point

Worksop
 

Setup for Worksop please guys ??? Mr Sharp !

Unfortunatly I never ran mine at Worksop Mr Bond so can't really help there. But you could use my set up as a starting point. :)

scratch
 

Looks like were gona have to start from scratch !

WORKSOP
 

Any chance the Drivers who ran RB5's at worksop could post your fiishing setups for us all to look at.

Cheers.

I can do better and give you karl's finishing setup...

Front: Light green #75 spring
30wt (ae) 2C piston
Middle hole on tower, outside on arm
Inner link inside +1mm shim, outer link, inside hole
1 Deg camber 0 Deg toe


Rear: Blue #68 spring
25wt (ae) 2B piston
Middle on tower, outside on arm
Innerlink outside + 2mm shim, outer link outside hole + 2mm shim
1° camber

All else kit standard. Karl wasn't completely happy with the car espeially the rear, and thought the silver springs as I ran in the finals would be a good idea to try.

Where did you finish fab? :thumbsup:

marshaling
 

well he was marshalling when I raced so not that good !! He HE !:o

I ran silver #70 with 2B and 25wt on rear and it was "Loose" but controlable. I wanted to go down to blue #68 but didnt.
Got the worlds conversion to try for next time, but will play before then.

Hi Mike,

Thanks Fab for replying. As you may or may not know Mike I borrowed the car that morning from a very kind friend Robin Lucas, the Transmitter was kindly lended to me by Big Bond, and I have to say I can not comment on all the set ups just yet.

However, What I think was correct regarding the piston was that they were actually the 3B ones.

Now I should know, but I ran 25wt all round, as they felt stiffer than the kit 2B pistons fitted to Bond's car and Ian Robinson's.

Go kit, but with 30wt next time as a starting point. Use the out hole on the rear wishbone, and the stiffest springs. Silver Fab says :)

2mm under the front inner caber position, not 1mm.

If you run Lipo, weight the car up.

Hope this helps, and if not, come a say hello if I am there next time.

I have not raced off road for over 6 years Mike, and seriously for over 3, so I just think I ran out of time to be honest and coul dnot do everything I wanted to do in 1 day without no practise.

On the whole, the RB5 was excellent, easy to drive and I think yesterday's run is a good sign of the potential it has, and will hopefuly give more guys the confidence to go out and try one.

Most say it is more stable and easy to dive over the B4 who have changed, I think we have a car that will suit the majority of people, and I hope to see more around next time.

Best of luck with your racing

Karl, I know you were using the 3 holes pistons but as you mentioned that kit setup would be a better idea that's what I put down.

On the rear end bit, you shortened the rear link, but wouldn't it be a better idea to make it longer and maybe flatter to help the rear end slide a bit mid corner?

well just got my Rb5 did the middle arm conversion. changed the factory diff balls and turnbuckles, The only problem i am having is getting the car to jump straight, Have tons of off power and on power stearing. Tons of traction,slight push still working on that. But wants to roll on jumps all the time still testing will post when setup is complete.

Nathan Ralls worksop indoor setup

FRONT

oil 35 wt losi
piston 2c
spring lime green 75
shock tower kit middle
wishbone outer hole
inner camberlink middle hole +1mm washer
outer camberlink inner hole
hub height low (washers above)
kickup 25 degree's
weight 10g on top of servo
ride height wishbones below level


REAR

08 velvet body, kit shaft
oil 25 wt losi
piston 2b
spring mauve,blue (imt told 72 but not sure, spring that comes with the 08 rear end)
shock tower 08 middle
wishbone 08 inner
inner camberlink outer hole no washers
outer camberlink outer hole +2mm washers
08 hubs medium wheelbase (no height adjustment)
rideheight driveshafts level
wing in middle mount position

NOTES

shoulder cut off the front pivot balls for rear wishbones, 2 white washers placed behind wishbones to shorten wheelbase, car ran on nimhs but is normally on lipo with no additional weight (untill i check it on scales) cells in forward position
kit wing with half gurney (flies very neutral)

car very easy to drive with bundles of steering, fronts and rear minipins run full with mr O medium foams, when outside inner and outer row cut off the front, full rear with same inserts


any questions feel free to ask

Looks very similar to my carpet set-up except

30g in front bulkhead, none near servo
short not super short wheelbase (will be changed for MK GP to see how it goes!)
Front springs losi black cut 1 1/2 coils
Rear springs losi blues (too stiff really but wanted stiffer than orange and didn't have silvers)
rear shock outer on stock tower (mid on Atomic tower I run) and out on wishbone, using 54mm shock shaft in rear (also the wider rear end but with normal length shocks and tower)

oils AE35wt all round

I am quite happy with this set-up at Dudley on all carpet (lapping about 0.1 off the fastest 4wd car in qualy which was a driver I should be competing with on level terms IMO). Will be going to Losi Silvers or Kyosho #80s (dark green) for MK GP as the slipper floor will require a little more rear roll. Might find I need even softer.

The key to the RB5 I found earlier in the year is not to run the front too soft .... basically forget the inner holes exist on the wishbones!


Basic outdoor set-up is similar to indoors other than Kyosho #70 (silver) springs all round and medium wheelbase + 2mm or so on ride hight all round.

The only problem I find with the RB5 is it's tendency to tuck it's nose in a little deep as you come off power, then only on carpet / ultra high grip ..... loverly everywhere else!!!!! Not being of national A final grade like nathan is I need a safer car so the stiffer front springs help there a lot. In fact I think that I have over compensated with the rear spring until I ran the stiffer fronts, might be worth dropping a rate or 2 on slippier surfaces.

This was my setup at the first (middle-)Swedish indoor series: Hit me!

What tires do you run with? I had problems finding the right front tires. I ran Schumacher mini pin in the rear. Tried mini pin in the front but I got a way to twitchy car. To much steering. The Proline 4-rib felt better when I found a setup with better steering but I still needed more steering. I am going to try Schumacher stagger. What do you think about that?

We normally run Scumy mini pins on the front and rear (in yellow) and trim a row or two off if needed to calm the front end down. I don't think I've tried anything else indoors for a very long time!

I have run my RB5 a couple of times at Oswestry, which is made up of carpet and wooden floor.
This is my current set-up.

Front.
35 cwt
2C piston
1.5 mm internal limiters
Neon Yellow spring
Inside hole of wishbone and no 3 hole on tower (AC)
Wishbones level
Camber link 2nd hole out on the inner mount (no spacers) and outside hole for the outer
25 deg castor
Running a brass bulkhead

Rear
25 cwt
3B piston
Nil internal limiters. But I'm running longer rod ends, to increase droop and also meaning the spring adjuster is not at the end of the shock body thread.
Blue (68) spring
Outer hole on the wishbone and no 4 hole of tower (AC)
Wishbones level
Medium wheelbase
Inner camber link in middle hole, nil spacers
Outer camber link on outer hole, 2mm spacer

Cells are run at the back
Worn schumacher mini spike (full) front and rear.

I find the car has plenty of mid and exit corner steering. It does hook its nose in if the power is taken off, but only on the high speed carpet section. I'm going to try a grade up on the front spring.

Phil, great to see you running the RB5 too!!!!

I have found that running on the inner hole on the front wishbone is what causes the hook off power.
Try the outer wishbone hole mate, let me know what you think. Oh by the way, running the front shocks at 20mm top of rod end to base of seal cartridge in the outside hole.

Where did you get the brass bulkhead from?

I got the bulkhead of Jim76, who I also got the car off.
I will try moving the front dampers, after the spring change.

so these last setups are still good for carpet?

my rb5 is on its way from the states as we speak:)

ordered schumis from models in motion on monday, but they still have'nt confirmed my order, any idea why? paid for with visa and everything.
