Just about.. Hard to come by here too. I think RB's business plan was to go full circle after they cheapened their brand name with all the Asian engines, and now they only want to sell expensive stuff. Unfortunately.. The Fires and Blasts were good value.. There is a German shop with at least one 2045 combo in stock for €219.. Few others for €229...

I have seen the Fire 11on eBay at times.

I have them in stock !

Mainly, whats the differences between fire11 and fire12?
The fire12 is easier to find...

Thanks, what does 'clocked' mean. What mods have been done?

I tried to get the sleeve out of the Blast V9, but couldn't manage it.. (Who the fxxx came up with the horrible idea of using flathead screws on an engine?..) It's got a huge gaping exhaust port though. So, not MES I guess..

Hi, For the people running the Rb Fire11, what have you found to be the best plugs to use with this motor?

Cheers.

I have been using the Odonnell 99, and not having any problems.

I researched that a lot before running my Fire 11. And everybody said Novarossi C5TGC/C6TGC (depending on weather)... So that's what I went with - and all good..

What size bearings does the Fire 11 take and what brands are recommended?

14x25.4x6 probably best to pull your bearing out first and measure it, just to make sure.

I agree with pulling and measuring. The Fire line of engines has always been pieced together engines to use up old stock so things change on them often and many times one person will get one that has different parts than one another racer in the same town got. As an example the exploded view shows the engine having an MES exhaust, but many of them are coming with a single exhaust port.

Currently am running a 2045 and getting 10+mins runtime. Problem I have is the 2045 manifold wont fit in the MP9. So, I could get a different manifold, but it won't look right (yes, call me a tart).

Have a few questions:
-Anyone know if the RB2097 is the same as the Nova9901 (shape looks very similar)

-How does the RB2097 compare to the Nova2096? Looking for a smoothish pipe on bottom and a strong top end.

The 2096 is identical to the 2045. The 2097 does look like a 9901, but it is not the same. The Losi RE12 pipe and header is like the 9901/41021, but not the same quality as the Nova products. I have used the RE 12, and it work well, for the right engines.

If running on the BXr, the 2097 should smooth power delivery a little compared to the 2045.

2097 it is then, was hoping to save a bit of cash as the 9901 is a fair bit cheaper than the 2097 in the UK.

I just ordered the BXR with pipe combo and trying to figure out what plugs I need to have on hand. I don't believe there are going to be a lot of people or sales with turbo plugs and I want to have what I need on hand. I see RB came out with new plugs but in looking at the posts here there is not a lot of chat about them. I live in north Georgia and will be racing around the area so for the next couple of month its going to be roughly 30-50 degrees. What plugs should I order and have on hand?

The couple times I've run with a guy running0 a BXR with 2097, it looked pretty awesome to me..

Here - the yellow one..(the other one is a Blast V1 - also looked quite good..)

RB Plugs have not been easy to get. Seems the US distributor changes every 1-2 years ever since I got into racing and some years things are easier to get than others. I started running the Novarossi C5TGC and C6TGC plugs and have had great luck with them in any RB I have tried them in. IMO it's good to keep medium and hot plugs for these engines, I seem to run the hot the most often due to my altitude.

If you can get the RB-01052-5B is really rather good..

Hey y'all, I'm a recent convert to the RB nation. I just bought a new WS9 from a friend in Singapore. I know its an older engine, but it only has a few tanks on it (just broken in). The price was reasonable, so hopefully I didn't just make a big mistake by not buying a BX or BXR.
I've read through most of the WS9 posts in the thread, any tips or suggestions on maintenance intervals or things to watch for?

The WS series of engines have always been my favorites!!! They are a square stroke engine with a smooth bottom end and tons of top end!!! Best part was they are a very easy engine to tune. One thing you will want to remember is the engine does not have a really aggressive bottom end. I used to run a 50 tooth spur on my Losi rather than a 48, so I could get a little extra grunt. Around here we have tracks with short run ups to jumps so I would change gearing or run heavier clutch springs. If you have an open flowing track this engine will be great with your normal gearing/cluth. If your track is tight and requires a lot of torque you may need to play with gearing and clutch.

Also they say to replace the rods at 3 gallons but I have never done that. I had several WS7 engines make it well over 10 gallons on the stock rod and bearings. Pre heat the engine and keep dirt out of it and it will last a long time as is!!

Can someone tell the OD of the rear bearing for the BXr....... I know the ID is 14.5mm

Cheers

Mark

26,0 mm. One of my very good friends bought a TKO rear bearing. Unfortunately there is a tolerance issue because the bearing can't get all the way on to the crank.

Lille, what do you reckon? I've found the following deals:

1.) RB Fire Combo, €175 shipped
2.) Nova P5XLT, €165 shipped
3.) Sirio C7LB combo (don't know which pipe) €185 shipped..

I'm thinking the Fire has the best power there?.... Do people really race with Fires though? Don't seem to see them much..

I race a fire 11 in my truggy and it is great. Where is that combo?

German shop.. Looks like they're being sold off...

Seems pretty hard to beat in terms of value for money. Even comes with the little front bearing cover(and 2045)...

The best way to find out, is to remove it and measure it yourself, no second guessing.

Those bearings are 14.5x26x6 just like the bearing in the Bonito.

Can you give me the link please? I can't find it.

You want to order from New Zealand?...

So far I've been able to control myself... :p

All I now is, the Fire is too much for a buggy. But, we have one driver in Denmark, who runs it in his buggy. I just see too many RB drivers struggles with there engines. I don't like Sirio based engines. Bad rear bearings and carb. I'm a Novarossi man, and I know that many other drivers has amother opinion :D

Well, my Fire 11 is still going strong.. And I think I still want that Blast V8, so I'm going to do my best to not give in.. For now anyway..

The F11 engine is a Nova based engine, not sirio based, at one time Sirio has or had owned RB, known as Star motors Co.Not sure if they still own them. The Killer 9 engine line I believe was Sirio based.

The Killers were Asian-built engines - Force I think..

The Fires, and all the Blasts are Novarossi-based..

I only mentioned Sirio because I found a deal on a CL7B, and I always heard (and saw..) good things about them.

But just for shxx's and giggles, what about the new BX and BXR? I assume they are made with parts from the Nova factory, but how similar is a BXR for ex. to a Bonito?

Not sure of any comparison with the Bonito engine, I only know of 1 person that ran the BXR, and wasn't real happy with it, and he was a Nova sponsored driver before that.

You always heard good things about Sirio? The SIrio CL7B-STI .21 was supposed to be good. But didn't they have crankshaft breaking problems. I seem to remember SuperTib getting into an argument about it. Seems Sirio drilled them too deep. Anyway, a friend had one. Front seal went at an early age. After replacing, the crank broke at the front.

I seem to recall that it was more a bad batch kind of thing.. I think they've always been pretty popular over here - and what I've seen of them running anyway was pretty convincing..

I only found out about the Sirio deal because I told another guy about the Fire 11 deal, and he was like, nnnnaaaaa, Sirio is so great, lasts forever, huge power, etc etc.. There used to be a guy here at rctech who was really big on Sirio engines.. - somewhere in Europe.. Forget his name, and haven't seen him around lately..

ps I HATED my (Sirio-built) Orion .24...

I have run the P5xlt, fire11 and BXR.
Fire11 is just a beast but seems to be a wee bit to much for me with the power delivery in my serpent truggy but still loved it..great on fuel.
BXR i am running with the 2087pipe and 198 header which proberly isnt right but its a great linear power easy to get the right throttle input and goes really good top end is close to the Fire but a bit more responsive...not as good on fuel but alright
P5xlt is a CRE modded...just awesome like the best bits of the fire and BXR put together...but i can drive faster with the BXR for some reason:confused:

I would buy one if I could understand german unless there is a way to translate the site?
