Hi Kevin,

thanks for your reply and related information, particularly about 'amainhobbies' however i would prefer to support the local importers/distributors that way I can be assure of their continued business and fantastic support they provide the racers in this country.

I may be wrong, but shouldn't you also be trying to persuade me to support the local guys?

hello CDS70

the reason i mention amain is because so many people seem to think there are no parts out there for alot of these engines, and thats quite the contrary.

since i am based here in the USA i try and recommend people to them because i know they have the parts in stock, even for the older engines.

i absolutly agree that you should support your local hobbyshops and countries importers but when you are on forums you cant always now where people are located, and my mentioning amain was because they have always agreed to carry the oddball stuff, even if its for older engine and it sits for along time.

there are tons of other shops here in the USA that probably carry the parts for these engines but none as active as AMAIN when it comes to making sure people know they have them or support a given line.

im not here to bash or slander any shops or importers, i do hope that you do continue to support your local hobbyshop and importer there

thanks again

whats happening C.Smith

long time no hear, good to see you are still on the scene and racing.

life has taken a bit of a turn for me working for the guys here at RB, its more about business and less about racing alot of times, although we do our best to be present at the big events. at the end of the day we need to make sure we are supporting and providing product to the shops that keep us in business, without them i have no job :) so hence the lack of being at more of the local races for the last year.

as for looking for RB stuff in the bay area, shoot me an email at our work addy, [email protected] and i will let you know where you can pick up stuff.

happy holidays to you and the family, talk to you soon

regards

kevin @ RB USA

I bought a R3 that I used for the last race weekend of the season. It seems great, and still has a ways to go before it's fully run in. I chose it over the Nova +12 because I liked the bi-turbo crank design, and because of Rody's personal customer service on the RB site. Glad to see RB bring it up a notch in the USA:nod:

can nitro cleaner be use to clean the engines after use.
when you say the engines lasted 3 to 5 gallons is that changing the conrod every gallon or two,and changing the piston and sleeve or the engine its self before changing anything to it.how often should we change the conrod piston and sleeve.
in on track performance what does the xenon lack compraed to the xenon r, what do i lose
thanks

yes you can use it to clean your engine on the out side .
the xenon is more of a club engine and the xenon r is a comp engine
and what you lose is alum sleeve and balance crank and some upper rpm .

Jamie.... you got email.

Kevin,
You comimg down to the WINTERNATS to warm up?

sent me a email [email protected]

jim rice

Got it. Will call later

How do you guys rate the Matrix RW? I have one in my G4+ but have only had it on the track once and despite having way too tall gearing it would hang with a friends Rody V12 on the straits and only lose a little out of the turns!
Also I am using a VXR "X1" pipe! Is this a good combo?

hello jim

i am not entirely sure if i will be at the race or not, i do believe however that jamie corrado, our new york sales manager, should be attending as far as i know.

i have a really full offroad schedule this year, something like 4 or 5 races in the course of 3 months time

i did speak with our guys in france and the hope is to try and get someone from europe to come over and represent us there at winternats but there has not been any confirmation of who or if its even possible yet.

i will stay in touch with you in the coming weeks

hope all is well there in florida and looking forward to getting togeather with you after some of the offroad races for a couple of beers

happy holidays and talk to you soon

kevin @ RB USA

hello FITO

the engines that i have seen go 3-5 gallons were all on the orignal rods and piston and sleeve sets.

on those same engines we did replace the rear main bearings after about 2 gallons, but this because the acid in the nitro is very agressive on the metal and causes the balls to break down so to be safe we replaced them with a ceramic rear bearing.

the rods have been very good on the xenon series engines, as for what you gain or loose on the regular xenon versus the "R", the R since its an aluminum sleeve engine will be much more sensitive on the needle settings but the power of the R is much better all around.

if you are an experienced racer i would recommend the XenonR, if not i just suggest sticking with the regular xenon thats an ABC motor.

good luck and happy holidays

kevin @ RB USA

hello 2strokeAl

the matrix motor is actually faster than the v12 series engines but is more sensitive on the needle settings. if you really want to wake the motor up try the E1752_2611 speedline pipe of ours, its designed for the engine specifically and we have had the best results using it compared to any of the other pipes in our lineup.

i am not familiar with the pipe you mentioned you are using, for the best performance i would suggest trying the orignal pipe we recommend,

good luck and happy holidays

thank you

kevin @ RB USA

What's the difference between the 2611 and the 2604 pipes and how does each effect the performance of the Matrix RW?

I'm using a 2604 on a Matrix RW and it seems to perform very well.

Very interesting reading, thank you guys. I run a modded and bullet proof C5, just wanting to know what is the best pipe set for the motor, we run a very tight track and the more torque the better. Also what is the reasoning with the C6 motors coming out with composite carbs and the older C5 motors have the alu ones, my guess vapour lock and easier to tune, if that is the case then it should be a sipmle swap? I run 8th circiut.

All the best guys!

kevin give me a call

kevin give me a call (wmay11 2013 for short tracks is very good )

hello michael1

i will call you later this afternoon, after work hours.

thanks

kevin @ RB USA

Dremelboy,

What's the difference between the 2611 and the 2604 pipes and how does each effect the performance of the Matrix RW?

I'm using a 2604 on a Matrix RW and it seems to perform very well, however I see that you recommend the 2611 for the Matrix RW.

hi everyone i am thinking of getting a C6 BB7T can anybody tell me how they are for relliabilty,im curently running an OS Vspec

Hello.......anyone there????? :)

hello CDS70

my apologies for the delay in getting back with you, there was info on the pipe i was waiting for from the factory and i got it yesterday

the 2611 pipe might be discontinued from the factory according to an email i recieved yesterday, i am trying to confirm that this is true, this is part of the reason i was hesitant in getting back with you on this question. i did not want to hype up the 2611 only for it to not be available

the 2611 pipe is a star based pipe where as the 2604 pipe is a nova based pipe. The 2604 is meant for use with the R3 and the V12's but can be used also with the matrix r and rw's with great success

if you have been running the 2604 with success i would stick with it to be honest, the 2611 might of offered a bit more run time or midrange but with its being discontinued it will no longer matter.

you can always experiement with other brands of pipes but sometimes if you found one that works with why mess with success

thanks

kevin @ RB USA

hello gary h

the C6BBT is our best selling engine these days.

the reliability has alot to do with your tuning abilities and how well you maintain the engine and the car.

in general we have very few problems with the engine. the use of turbo glowplugs was once thought to make the engines more difficult to tune but this is not true.

the engines will be very user friendly so long as you make sure all of the components that work with it are in good working order. clutch maintenance is very importaing with how the engine will tune, making sure your clutch bell bearings are in good working order will make a diference in how the engine tunes, bad bearings can cause engine tuning problems, worn clutch springs can create drag causing unexpected flameouts. these are the sorts of things i mean when i say maintaining the car

the OS is a great engine line and all of their engines perform well, or at least as well as the price related to the engine. The RG motor of theirs is a great engine for the price but wont run as hard as the SPEED V-spec, but then again look at the cost difference. Is one better to tune or more reliable than the other, probably not so keep this in mind with our engines as well.

hope that helps and please ask away if you have any other questions

thank you

kevin @ RB USA

Thanks for the info Kevin, appreciate your time.

hey all:)
i recently just bought a Matrix rw :nod:and have had one litre and about 6~7 tanks throught it and was wondering should there still be a lot of pinch or just verry litle as mine still got a bit of pinch
Any comments would be apreciated
Cheers Chris:)

Ask ya boss! He will know. Why do you ask, what have you done? :eek::weird::cry:

nothing wrong with my motor its going fine still got a fair bit of pinch just wondering if i should wait a little longer to start to lean out to performance

Whos this

hey i just got a v12 5 port, i could use any any break-in & running tips you guys might have, thanks.

Kevin,

any idea when the Xenon .21 Alpha will be available?

Thanks,
Steve

hi,
comparing v12 and matrix rw, which one has a better power/torque curve?

See my post half way down page 2 and dremellboys response about four posts down from that!

dremelboy or michael 1

I am considering the XenonR .21. My question is, what % nitro is recommended to optimum performance? Thanks in advance for your reply.

Roger

Roger,
Most pilots opt for 25% nitro in on-road.
Thanks for considering our line of engines for your chassis.

Roger,

25% is fine , I use 30% but i add .010 head shim, for fuel byrons 11% oil

Couldn't help but notice the Alpha is coming. Any idea's on a date. I need to get a new mill for the upcoming 1/8th onroad season.
Thanks

hello bsmooth

i talked to RODY this morning and the engines should be available in another week or two, we have had released alot of new engines since the toy fair in germany and are just trying to keep up with it all.

the pricing is not set in stone yet so i do not want to open up my mouth on it but what i can tell you is this

according to Rody the engine block has been beefed up, similar to the MSC (massive stiff case) design on all of our nova based engines.

the rear main bearing will be ceramic instead of steel, the carburator is aluminum and not composite and thats basically it. i have asked about a modified version of the engine but have not heard anything back on that one yet.

the engine from what i hear is just stupid fast, cant say its faster than the old xenonr, but with the new upgrades to the engine its surely going to be a competitor at the big races.

That's great to hear dremelboy, and thanks for keeping us in the loop. HMMM rebuild the MaxPower and +21 or save for the Alpha------The Alpha fo' sho'

Whats the difference between Matrix R and Matrix RW? Is it just EFRA vs IFMAR/ROAR compliance?

Just got home from the track after breaking in my first RB R3 (stock out the box). Half a gallon later, still running a little rich and WOW... :eek: :nod:

Definitely the fastest all around motor I've ever run. Low end like a picco and still pulling effortlessly at the end of a 240' straight. :D

where do guys get your RB products?
