Hello guys,

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

PS : the engine just for fun not race.

nice

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?

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.

Tks guys,

Grinder,

you mean the stock Matrix RW. 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
