RB .12
 

Hello guys,

any comment about the RB Speedline Matrix RW (IFMAR/ROAR) compair to the new line engines?? :sweat: (Like NINJA/NOVA PLUS). Tks

PS : the engine just for fun not race. :rolleyes:

nice :D

if its just for fun then you should have a good time

Wonder does the RB .12 matrix RW goes well with nova 2036 tune pipe???

What kind of temps do you guys run on your WS7's?

Just Curious
 

Does RB v12 replace the RB x12 engine? I have a x12 which I use as a backup engine and forgot how fast this was untill this last weekend when I needed it for a race. I cooked my OS TZ5P and need another spare engine for my tool kit. Wouldn't mind finding another RB x12 if still available.

Can somebody tell me what the difference is between 1003s7c & 1005s7c ? Also are the parts interchangeable with the ws7 series or any others ? thanks

I'm just getting back into nitro and was wondering for this motor with 30% Fuel will I need to shim the head from how it comes in the box ?

The Matrix is Serious. Very fast engine, especially tuned. :sneaky:

Tks guys,

Grinder,

you mean the stock Matrix RW. :confused: i'm looking for one.

Knock knock ..................anybody in here ?

Any body got experience with the ABC .21 Xenon ? (power , longevity , ease of tuning ec etc)

Xenon-R.....

First impression is awesome, fast engine for a good price.

But later impressions.....
after 4 liter the crankpin was conical worn out by 0.03mm, a new conrod did not fit the crankpin, it was very tight. After drilling it to the right size and running in it did last only 1.5 liter and than it broke.....

Yeah I thought it was alright too , until she started dropping glow plugs like nothing else . Seemed to me to be either leaning out at high RPM's or shimmed wrong . I shimmed it up and checked thru everything in the motor and fuel system for leaks . It kept doing it so now instead of being a cheap motor it is an expensive paper weight !!

Has anybody got the base needle settings for an RB XenonR? I seem to have lost the tune and want to start from scratch

Cheers

Main needle 6.5 turns out from closed .

Idle needle 5.5 turns out from closed .

I checked on the RB website and the idle needle is 8 turns out!!

Xenon is :

Main 6.5
Idle 8.0

question on engine choice, i have been thinking of the speedline matrix rw and also the new R3. does enyone have recomendations as to which engine might be the better choice ? things to consider are fuel economy, power delivery and longetivity. thanksguys.

Hey Patto. I'm currently running a Murnan Modified R3 with the novarossi 2630 pipe. I love it. I've only done two race days with it so far & I can feel it's still breaking in. I had more power this week than last and managed a 3rd place. It's still running fairly fat as I don't want to push it too hard early in it's life. Can't say about the matrix as I haven't run one yet. Also there is a separate thread on the R3 here as well.

Which one is the better engine? I have the Xenon (not R)

Does the RB WSII use/interchange with the WSIII?

The only difference as far as I know is that the Xenon is ABC construction and the Xenon R is AAC . I have the Xenon because I feel that ABC construction is more durable , but mine is stuffed now so what would I know !!!

wow, this thread been in active for a long time, if there's a new one for the on-road motors please re-direct me there...

are the c9 c10 c11, the same, and more or less 35 plus 21's? thanks

The c11 is the better of the rb's you listed. It has a better piston material, and more rigid block than the older models. The rb is different than the 35+21. It has more crank timing, lighter crank, different block. The Rb has more top end than the 35+21. The 35+21, and Rb parts are not interchangeable without modification.

i got the classico10 and it a descent engine ..it came with the 3003 pipe imo the 2018 bring the engine to life..i got this engine because im sort of a newbie to onroad nut ready to upgrade to the C11 its look strong:nod:

so would you say the c9-c11 has more top end than a 35 plus 21 tuned? or just over the stock versions?....lastlly do nova pipes work w/rb motors, 2015 etc etc..thanks

also the c11 has a different p/s/r set than this?

Yes. They have more top end than the tuned 35+21. The novarossi 2015 pipe works great with the rb c11. I like the medium conical header with the 2015 on the c11.

but thats the same p/s/r/ as all three c9-c11..unless the c11 has a different part number? i just wanted to see the different piston on the c11...

The c10, and c11 have a lighter, more durable piston than the c9. I'm not sure of the part numbers without looking them up. The c10, c11 piston is definitely an improvement.

Will a Nova SCT crank drop into my TJ10?

No. It is not compatible.

Beside the timings, is it the crankpin making the difference or is the whole dimension of the crank different?

The Sct is 11.9mm, and the tj10 is 11.5mm. Also the Sct is long stroke, and the tj10 is short stroke. The crankpin on the Sct is further from center than the Tj10.

I have used the 11.5 long stroke crank from the +12-3ct in the tj10. It works, but makes too much displacement to be legal for racing. The larger diameter short stroke piston with the long stroke crank. It was quick, but guzzled fuel.

Thank you.
I have a Nova crank, I will post a pic of it later. Will you be able to identify it for me? It was given to me by someone at my track. He says it will fit. I just would like to know because when I buy another engine I would like to put it in the TJ for experiment sake.

RB T11 RS
 

Dear all
What do you think about the RB T11RC?
Would you recommend this engine also for tight or small tracks?

I'm looking for an engine with very good bottom performance!
So now I'm thinking between Sirio Nemesis, Reds ZR12T, Nova Flash, Max XXL3 .12 or the RB T11RC...

Can someone give me a tip?

Kind regards

Have you thought about getting the IDM/Picco Torque? Plenty of bottom end for a tight track, but also capable of holding it's own on larger tracks from what goes on in the Picco/IDM threads.

Hi Djshakespear

Thanks for your reply.
Yes I thought about. But the fact that everyone here in Switzerland is racing the Picco I prefered to race an other engine.

Just like me, I like to be the odd one out :D

So you know what I mean :blush:

we have a RB and Nova dealer here in Switzerland, where I can get parts..
But I don't know if these engines will be the right one.
I think, I'll wait till the new REDS .12 engine will come out in mid september.
They will be Picco based, and so I think they will be torquey..

Just wondering what nitro % I should run in an X12T? cheers
