There doesnt seem to be much on here about the 2015 range from RB yet, looks like nice improvements on already solid performers. Personally I'm stoked that there is a pretty standard LS5 in the range which was always great as the previous BX and later BXR LS5.

Weve got them hitting us in the UK today / tomorow so I assume most countries will start to see them making appearances soon.
Bit more info on here, on road ones to be added to the site yet.

RB Say:
-The 2015 off-road engines line receive the complete new internal parts, carburetor, high level features, etc… to make it easier to use with great performances ! Also, the new line is easier to understand with two top level racing engines (1 Long Stroke and 1 Super Long Stroke) and the little brother which is great and with a friendly price level.
There is also a new RB EFRA homologated pipe which is under production and will be available soon.

Yeah. The new RB ones haven't made it to the states yet, but I am hearing nothing but good things from the team drivers running the LS5 plus.

What's the 2087 pipe like compared to the 2045? I don't care about run-time - just power.

I haven't used the 2045 yet, but the 2087 has very good bottom end and overall power on my buggy with the medium compact header. I have only compared it to the 2097 and a Nova 9901 and I prefer the 2087.

In France we have many topics on the RB products company closing definitely on last week's Thursday :(. Is it true ? Two guys at our club confirmed it this afternoon.

Whaaa??...

Confirmed :( RB is gone. Here's one of the topic :

http://www.yome3000.com/forums-lire.php?id=7323&f=6

That to me looks like old news. They just released the 2015 engine line. Looks like they may have had to file for bankruptcy(due to one of their shareholders being bankrupt, apparently..), but will continue to operate. As many companies do...

Edit - Ah wait.. My French is ..... basically nonexistent. But I did have a little Latin in school. So at the end of that thread it does look bad.. That's awful...

Unfortunately RB Products will closed definitely next monday and all products will be auctioned.
It seems that Rody Roem would like find a solution to save the RB name and engines...

It would be great if Rody could get RB back upin the winners circle!!

The problem with RB is all the stupid products they are now selling, to me they should of stay as an engine company. You could see how they come up with a Kanai edition and the engines set on the shelves of the hobbyshops until they were put on sale.
To me is a shame because I loved RB engines like the WS7-II the C5 and C6 and today I have a couple of friends that run RB engines that are missiles but to me they just tried to do to much at the same time.
They should of take it slow focus in their engine range and continue with really renounced pro driver program. If I am not mistake Savoya won the 3 europe championships with RB Engines.
Lets hope that Rody can bring the company back to the its origin and they can continue developing bad ass engines.

Rody hasn't been with RB for many years. Rody designed/sold TecnoPower engines for a time, but it didn't work out.

It's a huge shame if RB doesn't pull through somehow.

The problem as I see it is the overall general development of RC over the last 10 years. There was the MT explosion with Savages and LST's etc.., which is what got me into it. Then when that started to fade people started in with truggies, and some even went to buggies. But in the last 5-6 years or so it seems everybody wants to go race a bunch of different stupid 10th scale flashlights... I mean seriously, 2wd 10th scale buggy?? WTF is that? I mean, besides a retarded child's toy? Makes me think of that forum icon of a child rolling a toy car back and forth...

Anyway, maybe their RTR buggy or whatever wasn't the best, or maybe it was just a valiant effort to carry the torch of 8th scale nitro further, but it was doomed to fail, with all the flashlight distractions out there, not to mention quadcopters, bad economies, etc etc. And also not to mention the general development of 8th scale nitro racing.. Got to be a Speed(two, one as backup of course..), got to be only for the very überserious(second kit under the table for spares, 12 sets of tires..), etc..

RB is not Intech or SOAR or any of these other little upstart companies, but a big-time player over the long term. I hope they pull it off somehow and stay in business.

Found a couple hours to go out today and burn some nitro. Took my ancient SC8 out wth an RB Fire in it. Hasn't been touched in 6-7 months, and probably hasn't had the engine out since the year before last..

Started right up, and rrrriipppedddd. Definitely an awesome engine... - one of my favorites of all time. Absolutely devours my modded Beat B5.., and more muscular than my Piccos.. I feel a bit like the last guy at the party though, going "hey, where'd everybody go?", in that I just like running nitro for fun, and am not obsessed with racing and getting 8 more seconds of run time or whatever.. I was just blasting around a parking lot at first. Then I went to a local asphalt "track" and ran with some guys running Inferno GT's... Smoked 'em.. ;) (short track, but still.. The Fire is a beast..)

Hi guys , does anyone know the base carby settings for an RB BX R ?
Cheers.

Hi guys.

Are the RB motors a hotter running motor?

I was racing mine on the weekend and it would come off the track at 230* even with a rich tune.

One note, it is still pretty new. Maybe 25ish tanks on it now. Its not very fast ( its not a total turd either) and doesn't have much low end.

Is that because its still new?

I was told it will wake up around the 1 1/2 - 2 gallon mark.

Thanks

That isn't hot for an RB engine, it's really rich, they will run normally 250-270 range, depending on track size, elevation, and outside temps, 265 is quite normal, what carb restrictor is in the engine? For breakin, 8.0 (Red) is best, when it's broken in all the way, then drop down to 7.5 (orange).

Wow! Really, that hot?

I have the 7 in the carb now. Running Byron's 30/11, Novarossi C6CTG ( think that's the right number) plugs.

Your fuel and plug are perfect, when you go with the smaller restrictor, your tuning window gets smaller, making tuning more sensitive, with a perfect tune, you can still get good fuel mileage, and an easier to with larger restrictor.

But these motors really like temps in the 250*-270* area?

Oh Yea, I have seen RB engines going over 300, not all the time, and still have great compression, and go for 7-8 gallons, I wouldn't recommend running 300 always, but, they run better and a long time, 265- 270, and get 8 to 10 minutes a tank.

Wow. I'm still surprised.

Now, what about temps that high with an engine as new as mine ( 25ish tanks )

What are you outside temps now? Are you using a head heater to start your engine now? I'm in Arizona, so we already have instant heat, the summers are when we get real hot, now it's not to bad for engine heat, 2 wks ago I was in Vegas for the Silverstate race, it's was hi 80s, my truggy was running about 260-270, I was getting 10 minute pit stops for fuel, make sure bearings on the clutch, and wheel bearings are all free, any drag at all, you should be good, if your still in some cold weather, it may take some leaning to get your engine up to 250.

The weekend race temps ranged from 0c (32f) in the morning to 15c (59f), so on the cooler side. I an using a head heater.

The race was indoors but because in was nitro the building was not heated because large doors were open to keep the air fairly clear.

Indoor adds a not her complication for tune and heat, ai4 gets thin. Was that the same race Monty Houston was racing this past week?

Yep. Same one. Met him on the Saturday. Nice guy.

Yea, he's a super nice guy, he is one of the best engine guys I know, he has a Web site, deals in Fusion engines (NOVA BASED) also has a thread here on rc rech, Houston engine service or Fusion engines not for sure which one.

Yea, it's Houston engine service H.E.S
and another he has is Fusion X engines.

Ya. I Read his thread (HES) all the time. I wanted to ask him to look at my RB but everyone and their brother was asking him all weekend. I didn't want to bother him more....lol

He's pretty fast too!

Yes it was. The RB like to run in the 250-270.

Hey Chris, how is it going? Where at the race in Canada that Monty raced in also?

I don't think one if my questions got answered.

Is 260*+ too high this early in? I'm only at 25ish tanks and have been told to try and keep the temps around 200* . Now the person helping me with break in/tuning is very good. Maybe he just doesn't know that RBs like the higher temps.

I didn't know that was the Kani version, never heard anything about that engine, all I know, is it's a 3 port engine, and Dom
nt know of anybody that has had one, I have stayed with the C6, and some of the blast engines have been good, modded engines havenworked good.
keep in mind, you are not going to run that engine at 200 And be competitive, too low of heat is just as bad as too hot

My bud ( same guy) runs a Nova P5XLT ( pretty sure that's the right numbers...lol) and its plenty fast and he's just as fast any anyone else out there on the weekend. Hottest he came off was 215. Most other times he was in the 180-190 area.

Wow, impressive, you guys are in a whole different climate than me, if it works for you, thats great, I don't know of anyone out here running those temps, good luck.

I couldn't make the race. It is not real warm. Although Sunday was nice.

215 is on the cool-ish side for a race temp(not cool in a bad way, just cool as in not-that-hot..), just coming off the track IMO.... 250-260 is totally normal afaic. 280-290 I start wanting to change things.., but depending on conditions even that is probably OK if you're coming off the track at those temps..

I'm not a guru or authority. Just my experience.. I had a Go once that consistently ran 290-300 - and it ran well... My target temp though is 230ish, give or take 20...

Also don't forget, there's probably a lot of variation in the accuracy of temp gun readings...

Ok. So it seens the general opinion it that I shouldn't worry about trying to keep temps below 200*. The RBs are best at 250*-260*.

My temp gun is very accurate. Tried a few of my friends temp guns to compare readings and mine all 4 were within 4* of each other. My other friends was 20* off the rest of us.

Does your engine still has mechanical pinch? If it does the engine is going to run hotter because of that.Dont worry to much on temp, Some engine like to run hotter or colder then others of the same make.

I wouldn't worry too much on temperature.

as long as the engine is making good power and a decent amount of smoke and sounds right its all good.

As other people have said with the engine being new and possible still having mechanical pinch it may run a little bit hotter until it loosens up.

I used to run an RB BXR and it ran its best at 240-260* Fahrenheit. This was with a RB no.5 turbo plug.
