Thanks Chris.

Thanks Chris! I'm just looking at my options and make a decision. Looking at B11/X11 or Fusion X7. Jim will get my business no matter what. Still using my Crono RS5. The last RB I owned was the original WS7 and I struggled with that carb to get it just right. I know the new ones are very good. A friend bought a Rally 9 and put it in his son's Mugen Truggy and he was extremely surprised and very happy.

Looking forward to the RB engine warmer.

Thanks for your input.

Will a Nova 9901 or a Dynamite 053 work well with an X11?

Both pipes will work on the X11 fairly well. I would say the 9901 would be better tho.

Hey CP! Nice work this weekend man! Hope all is well in D town...;)

Thanks man!! All is well here, but the season is coming to an end :mad:

How's it going up North?

The track in Burlington for this race was awesome!!!! Here is a short vid of one of the qual rounds man. You gota make it back out one day :nod:

+ YouTube Video

Will definately try and get to State next year! It would be good to see everybody again! Ok... Sorry for the thread hijack! Take care!

K10
 

Thought i would add my experience with RB engines.
Bought myself a K10 for my buggy as it was a great price with good reviews. I will say now i have only run Novarossi in my buggy but was always interested in RB as they are a very similar engine. So far i am very impressed with the performance of this engine. Its a screamer. It tunes very well, no mid needle but its not really needed anyway. Im running it with an RB 2045 pipe. It produces a lot of power and as a result i have run a bigger clutch gear (15T) as it pulls it so easily, and the engine tunes so well you can use variable throttle for long periods (not full or full brake) with no issues of fuel loading up, or stalling. So now i have a buggy with more top speed potential and more throttle control due to the very precise carb.
I have only run about 9 tanks through it, so i cant really comment on life span, but, i can say it still has a pinch when dead cold between sleeve and piston, which is a good sign.
Comparing to Novarossis is a hard task for any engine, but so far it looks good. My experience with Novarossi has been all positive. Amazing life span when looked after, best i have ever seen. In fact, i run an old Novarossi BX21SBK01 short stroke in an old Ofna Dominator truck still to this day and it holds tune and pulls very hard! Lots of comp. It also pulls a bigger clutch gear than the stock truck came with (i have a video on youtube of the Ofna running it if anyone is interested ;)
Sorry for the long post, but, if your on this thread looking for info on RB engines i feel i got something to add.
Cheers.

Hello guys ...

What RB model is more like NOVA PLUS4?


There is much difference between the X10 and X11?

Thank you, sorry my bad english: D

The X11 would be the closest RB to a +4 IMO.

The only difference between the X10 and X11 is the crankcase and the etching on the cooling head. I put a ceramic bearing in the X11 I have and it really woke the engine up and the fuel economy improved as well.

Chris,
I thought of buying a GO GXII 5RHO, you have some experience with this engine? It is stronger than X11?

I like the engine smooth and balanced, with good bottom end and top end. also fuel economy

I'm in doubt between three engines.
RB X11
GO GXII
B6 Werks

tks!

I have not even seen a new GO run in person only in videos. I myself am just a believer in the old saying of you get what you pay for. Sure almost all engines you get these days are going to make good power. My RB's all last me 12-15 gallons of fuel, many times I run an engine for an entire season and let another racer run it the following season.

Of course you need to do what you feel most comfortable with so make sure you get what your wallet allows, times are tough these days. I have always felt the carb is where you see the biggest difference between a $200 engine and a high dollar engine. I don't think it's a coincidence that OS, and Novarossi manufactured engines are the high dollar engines, and those seem to be the two carbs people always use on the low buck engines when they start having problems.

Again this is just my opinion and there are thousands of people out there who have awesome luck with the cheaper engines.

Hi friends someone has tried this product rb, is useful and what exactly improves, we need another type of flywheel and clutch.
Thank you.

Most flywheels, like the serpent 811 and the losi 8, have this bearing gaurd already incorperated in the flywheel. Look at this picture, that flang under the flywheel does the same job.

That engine protect actually helps protect even better than the flywheels that cup the engine case. The engine protect fits very snug where it would take small sand to get back in there. I run the Losi flywheel and the front bearing stays much cleaner with the engine protect than without it.
