Why should I choose RB5 over B4
 

I currently have a B4 and like it. But I do like the look of the RB5.

What I like from a car is it to generate plenty of drive, my favourite 2wd is the Losi BK2. Ive also liked the B3 more so than the B4. I am running the B4 with 4 degree of Anti-squat and it seems to suit me like this.

But I just fancy a change, and wonderring, who can persuade me either way... ;)... do I, or don't I.

Chris

borrow a set-up one and see what you think, that's the best way...

I'll admit I bit the bullet and and bought one. Easier to drive than the B4, and just feels more consistent run to run.

steering of a B4 with the rear drive of BK2. What's not to like! try one, it's a good car, and built like a tank too.

I spoke to Woody earlier, thanks Stu for that advice.

Borrowing one would be good, but for me that wouldn't give it a true test as what would be a good setup for one person may not be for me. I may just bite the bullet and take it on.

Good answer, are you sales person? :lol:

Chris, if your at Broxtowe this Sunday your welcome to have a go with mine. :)

Thanks Richard, Unfortunately I won't be there. Id like to be as I really enjoyed the Xmas Cracker, but I am doing the Endurance race at York which I am also looking forward to.

You know you want to get a Losi! But if you were in the market for an RB5 i think Fab might sell you his....

Hey Rob. Well a Losi is tempting too, but with the option of Fabs I just want to make my mind up first. I know he broke pretty much everything yesterday but he's got all the new bits to fix it. :lol:

Oh yeah i forgot he put it through the grinder yesterday. Maybe you should let him put it back together first!

how the heck did he manage that? I only broke a rear atomic tower on mine on the big table top at eden park, and that was in nearly 2 full seasons use!

put associated blue turnbuckles on it though Chris, as the stock ones do bend!

oh, and i don't do sales, far more boring than that!

You know Chris, I just might have a go too :D

G

:thumbsup: Im liking the idea, more so with the fact you may be aswell.

Now we just have to get the J to the Dicko on board and we're set :lol:

G

Ohh dear :lol:

Didnt think there was a job more boring than mine!

We have 24hrs to twist his arm next weekend... :lol:

As you all know I am the RB5's biggest fan .... it is, without doubt, the best 2wd I have ever driven!

If pressed I'd say take all the best bits of the AE and Losi cars and mix them together, add an extra helping of easy to drive and your getting close to the RB5!!!!

I also vastly prefered the B3 to the B4 ..... the RB5 is as consistent as the B3 (if not more so) but maybe a little more front end both into and out of a corner.

I have tried several cars over the past season (borrowed and palyed with set-ups in my own time not just a quick drive at a meeting), I still don't like the B4 at all, the Losi is a good car but feels a little nerveous compared to the RB5 (probably more to do with how stable the RB5 is rather than anything too much wrong with the XXX-CR), the X6 seems really good on high grip stuff and a little looser than an RB5 in the wet, the S2 I tried wasn't right for me but it was the longer version.

Nothing has tempted me away from the RB5

You can have a go at it at Jarrow if you want. I'm getting setup advice from the US ATM.

I'm getting more and more tempted..... :D

Nice one, If you want to swap cars for one or two rounds we could? Perhaps for the full day? If you have MSN, Pm please it to me mate.

Even i want to try one now :woot:

Make your own 2WD Chris?

Hey id love to, and I would if I had the time and the tools. But im looking forward to the rumoured Schumacher 2wd (which I know nothing more about than the rumour before anyone asks). Infact, id run a D2 and think i would be already if they were available.

chris / northy

i've just bought a second hand one if either of you want to borrow mine at the next round of bury 15th feb or the next worksop meeting your than welcome to

paul:)

Standard kit suffers from understeer and worlds kit suffers from no rear grip, in my opinion.

if your good enough to tweak the setup and balance the 2 issues then it has potential.

If you get bored after 5 minutes like me, then get an X6. :p (sorry Chris couldnt resist)

Hey the X-6 is the best 2wd out there and the squared looks even better! so its a good suggestion. I just needed a change.

I quite agree with that. Best my RB5 has been was Worksop round 2 when i swapped to the new rear end, the car was really good and I even managed to get 2 top 10 rounds (not enough for an A but top of B). I was still running my very old 3700s back then and the switch to the new rear end made the car rotate in the slow corners and stopped it sliding in the fast seeepers.

Then I went to Lipo and since then I've been struggling big time. This week end I started with no rear end grip and finished with no steering. I've added 100+g to the car so the car's not too light anymore.

As I said I'm waiting for a reply from the guys at Kyosho USA, sent them my setup for both cars and a description of the handling, we'll see what they come up with, but at the moment I'm thinking that the car may just not suit my driving at all. I like a car with a lot of steering but I don't seem to find a good combination of lateral grip and steering. If I have grip I don't steer, if I have steering I have no grip.

Have just switched from B4 to RB5 and had mixed results. I think the B4 is slightly better and quicker indoors but its outdoors that counts and from what ive seen the RB5 is a much more stable car on a bumpy track and can be pushed harder when there is high grip ie grass, astro. I think it just struggles on the low grip surface like at worksop. Mine was good at Bury where there is more grip and is no better or no worse at broxtowe than my B4. I just cant wait to try it outdoors now though...Im sooooo fed up of this indoor stuff...:bored:

I would just like to add my 2cents to this and say that the RB5 is a wonderful car to drive, as RogerM said it's like the B4 steering and the forward traction out of corners is Immence. BUT the one thing i noticed with the kit set-up is the amount of bump out it has so i set mine up with 0 bump, 1mm under outer steering ballstud instead of three and the car was transformed and was 1sec + faster per lap and alot more 'even' in and out of corners and with excellent on-off throttle/steering control if you know what i mean. GET ONE you won't regret it

Have to say, the RB5 was great at the Petit RC when there was a lot of grip. But I mostly race buggies indoors, for now, and can't find a balance that suits me.

looks like you 2 are having the same dilemma i had about 4 months ago,

having not gotten on with my b4 but loving the x6 to bits i found the thought of trying a rear motored car again to be almost total madness but a local racer asked me for a bit of help setting up his original rb5 over a year ago and the idea of trying one has nagged at me since then so i decided to bite the bullet for the winter knowing i can always grab a last minute x6 if i didnt like the car. having said all that and still with limited running i can honestly say i havent looked back since i got the car. i ignored what most people said with the problems between old and new rear ends as was told that if you run the old rear end you have to add 30+g as far forwards as possible but dont use the new rear end as it takes all the grip away when you have the extra weight up front. personally i didnt add the weight on the nose and got the new rear end. i have 10g on the servo to stop the car wheelying and have found the rb5 to be as safe as the x6 to drive but with more mid corner pivot or rather a more predictable pivot with a slight push when giving it large out of a corner. i have set the car just above the min weight limit and it feels light supple and alive to drive and returns good lap times for me.

the car is unbelivably strong so far even without hopups and spares are nice and cheap as well. im gonna treat it to alloy hinge pin blocks and AC shock towers soon but that is all :D

Have you run the RB5 outdoors Nathan? How is it there?

When I had a Yokomo MR4-BC, it was awsome indoors, and as the outdoor season came I started off practicing at Bury on my own and it felt ace. But then when I was at a race meeting, I realised that at its limit it was actually far slower per lap than it felt compared to what others were doing.

Anyway, I forgot the point to that but ive typed it. Oh, what I think I was getting at, is does the balance and laps it achieves on the flat stuff transfer to oudoor stuff? I know Big Hans can get it going really quick around Southport (with only air in the shocks sometimes!!!)

Chris

Chris, the RB is good indoors but it really comes into its own out doors, thats where its best!! :)

this thread is magic. I ran the BR5 for 18 months and no one wanted to know the car (except Woody). Now i've moved on from it and everyone is jumping on board! lol

rb5
 

had mine from day one.mainly used outdoors, never clean it or adjust anything and it just keeps going.cant see why any problems with grip in slippy conditions outdoors.spares were cheap,but very rarely needed.thanks jez.

have run it at stotfold before i got the longer rear shock shafts and it struggled with lack of rear droop over the jumps but was composed at all other times. i now have the longer rear shafts so will be going there in 3 weekends time as have the 24hr and belgium to race at first :blush:

Apparently we're running the car way too stiff. That's what I was told anyway.

funny .. no one has mentioned the rb5 shocks - 1 of the best, if not THE best out there!!

Yes defo one of the strongest points of the car.

After running the car last season the key areas where the RB5 fairs better than the B4 are no doubt- over all build quality, strength, stability & handling. It is more of a consistant & predictable car and is also easier to work on. :)

Both the RB5 & B4 are nimble, offer a lot of turn in and are easy to set up but the RB5 ticks many more boxes.

Of course the one big box the B4 ticks is history & results to date but this doesn't make it the best car. The RB5 is the better car! :thumbsup:

Que Tebo and a worlds win ......... maybe!
