what happened with the S line of rb engines?(s3, s5 etc) I assume they have been discontinued and replaced with the 9 series?

Yes, they have been replaced with the junior (S3) and hobby (S5). Basically the same except for the lighter cooling heads and aluminum orange carb pinch bolt assembly.

Help with C5
 

A buddy let me borrow his C5 that has just been pinched and had new bearings installed. I'm running a 053 pipe. I'm new to RB Motors, noticed that the new lineup of engines are way different than what my buddy lent me. I was wondering what a basic starting point for tuning would be and what would be a good engine to purchase for a small to medium track?

Have a S7 motor(Have no complaints, just compliments) running the 2045 pipe with it and the 192 header,combo deal that i got. Don't like the way it fits in my MBX6(pipe is to long for me, it sticks out past the mud guard,,,,,,,,is there another pipe that would work well with this motor???? thanks for the help!

Im running a ofna 086 on my s5 and I love it. I ran it in my truggy this past weekend and I had spectators coming up to me asking what I was running. Not only does it have a pissed off sound, it has a ton of bottom, which I really wasnt looking for, I can break the rear loose on demand. I ordered another pipe, the dynamite 086 to try on a new motor, the reason I like the dynamite is b/c they come hard coated.

Hay ya'll,

Just picked up a Hobby 9 for my Z01-b. Any tips for break in? I'm gonna try my dynamite 053 pipe on for now, anyone else try this combo? I run on a medium sized track with tight infield and a couple of sweeping turns. Also, what is a good plug for this motor in really hot/humid conditions. Will O'donnell plugs work in this motor? I have a couple of 99's lying at home. Thanks for any info!

im figuring that 99 is odo99t. thats the far best turbo plug iv used on anything it will fit. in my mod turbo button s5 iv tried every pipe and from full to empty tank with consistancy both the 083 with short header(smooth powerband,great runtime) and 2045&192mm header(very strong,10+min runtime) are best. with your hobby nine(being the big new rb engine!) id say 053 might be perfect. my s5 naturally lacked top end. your hobby nine i hear is about the same as a cbb6 and lacks a little bottom. that 053 should be great. iv seen a lot of c6 guys run jp1 or an rb pipe.

heat it up and go. break in shouldn be too bad. that hobby nine should be awsome

Anyone here know when we can get the RB magnesium heads:confused:

No my Hobby 9 is a standard plug version. I got the odo99. I'm hoping that 053 works good.

Unless they are coming out with a new one, the magnesium heads were limited production a few years ago. I have one but I don't want to mess it up.:p

???? I sure hope not i was going to get 2:(
Say it aint so Jeo

no doubt the 053 will be fine...tho sometimes is nice to check out others..

Yup, that head came out a couple years ago. Good luck in finding one, I searched for awhile to find one. They are nice, it is 1 ounce lighter than my C6BBT stock head.

I am running a S5 which is the same as the hobby 9. Iam using a dynamite 053 and o99 plug. IMO it is a great setup. The o99 plug is the only one my motor likes and it last forever. I tried using an os plug and the thing kept dieing. the 053 is just about right for this motor and on a medium size track you won't be giving up anything.

i have been a fan of RB engines for a long time but i am losing faith fast. the piston rist pin clip came out of my newest ws7III with only 2 gal through it. i understand things happen and can live with that but what really bugs me is that twice in the last couple of months i have tried to contact RB and they don't respond. 1st time i was looking for a part # for a replacement screw for the carb and i left a email message and recieved no responce(2 months ago) and this time when i called the message said to leave a voice mail but the mailbox was full and it wouldn't let me. when i spend this much money on a race engine i do expect some level of customer service. i still believe RB engines are some of the best built but i think i will be looking for another company if things don't improve.
i hate to flame a company on line but feel they need to know how their customers feel and if they don't answer there phone or emails i don't know any other way.
randy

The best way to reach RB, is email, [email protected] He's the new RB-USA Manager, this is his personal email, and he does respond, he's still trying to clean up the mess that the previous US distributors made. He's a good guy, was with Traxxas for about 18 years.

From the moment that forum went down, which was the only source for any information regarding RB products, things became very difficult RB fans. And it only leads people away eventhough quality is were it was.

i understand having problems but after several months it looks like they should be able to aswer the phone or an email to the posted company contact #s. i work in a hobby shop and run a off road track and am very busy so i don't have much time to spare but i try to return calls and aswer emails. i just think it may be time for me to try another engine manufacturer.
:(

i also love my RB's. But ever since Rody left and they closed the forum they seem to have dropped off the pace worldwide.

It is really sad you guys are coming down on the man. He is trying his best, I don't think there would be a problem if there wasn't a big release of new engines and the demand wasn't so high. I work at a hobbyshop too and new RB retailer. He has been great to us, I sold all but one of the nine engines I ordered in the last two months. I tried to order a " Hobby" 5 port and we did not get it, already backordered. So I don't believe it is his fault I think it is RB's in France getting the engines here.

i am not coming down on him hard i don't think. i just said i like better customer service. i believe RB engine are among the best built and i am sure he is working hard to get it together. he should at least have someone to answer the phone and emails and even read this forum and respond to questions. i will say no more, just wanted to put in my 2 cents.

same here. I love the RB motors. i just bought another one

my problem is that they closed there forum and there is no one providing support for the product anymore.

it used to be if you havd a tuning problem or any other problem, you could go to the RB Forum and ask a question. Rody would always give you the right answer.
Now there is no one there to answer the questions
their forum was one thing that made them such a great engine producer

it still wont stop me from buying an RB. but it might sway me to look at other brands in the future

What is sad about it? I dont care what all he has going on, he can answer his phone and answer emails if he wants to keep selling motors. Like Randy I have called and sent countless emails to them in the last couple of months and finally got ahold of somebody after 50 tries. If you cant do better than than there is an issue. "Sad", dont think so

How is the new line of motors? I was all gun and ready to grab a WS7III to find out its no longer made :lol: they changed the number system on me. I was thinking of picking the S3 up now, to get me started and get my feet wet again, and then move to like the S7/S9 , but not sure. every place i looked , there on backorder.

The WS7 iis now the WS9. Smoothest engine i've ever had!

I have the Hobby 9 5port and its a very smooth engine!!:tire::tire: Holds a tune well and runs well at around 240-260. I have one gallon through 25% Byrons with the original plug still in it. RBs are great engines!!! The Hobby 9 is perfect for someone on a budget who wants good power throughout.

A few questions about the 9 series.

It is still NovaRossi Based right?

Has anyone tried to fit the 9 series parts into the "s series" s3,s5,s7,ws7?

That is one thing I love about the s series is that all the parts are interchangable. It would be awesome if the 9 series parts would fit the older s series line.

It may be the same. The carb settings are the same as the S series ( 3 1/2 HSN 5 LSN). I have an S3 that is an absolute pleasure to run.

I would just about all the new "9 series" parts are interchangable with their prior models. Some of the new parts are things like orange aluminum carb pinch bolts and lighter low profile heads with less fins.

Hey Jud I forgot to show you today I got a RB 2045 w/192mm header. By far the best pipe combo I have ran on my C6's. Worth the money in the performance you gain.

Who has the New B9??? I loved my C6's and I am wanting to try the B9 now. Hopefully someone has been runnng one for atleast a few gallons, I am interested in what you have to say.

Thanks

That's the short header? I had that 2045 and I sold it with the s7 I had:(. Damn should have kept it.

I have a RB WS 7 III that is do for a con rod replacement. I cannot remember whether the solid portion of the wrist pin faces the exhaust or intake side of the piston. Any help would be much appreciated!

Rick

When i open the rear plate on my usa spec i can see the RB logo on the rod dont know if that helps you

thanks that clears that up :smile:

Thanks Buggydad. I was looking more at the wrist pin configuration. If you look at the wrist pin it has a hollow side and a solid side. I need to know which way it faces when assembled correctly. You can look through the exhaust port and tell. I took my apart and forgot how it goes back together!
Rick

There is an article in the August issue R/C Car magazine showing how to replace a piston, rod, and sleeve. It may be on there site, www.rc-car.com

Hi Rick57

The solid side should be at the exhaust port side. Which means if you look from the exhaust port you should see the solid side. :nod:

Does anybody has any idea whether RB shut down their forum or what ?. Been trying since yesterday and the link is always broken. :confused:

unfotunetely it has been discontinued. the past couple pages here(rctech)have discussed the fact that the rb forum was one factor into buying rb engines. after rody left the forum closed. hopefully google or this thread can help you.

Thank you, was just trying to check on this ST28 enigne someone selling over here but couldn't find such model in RB site except MT.9 that looks identical. Heard this ST28 is a RTR engine that comes with the Savage ?

hmmm. im not too familiar with any mt engines....
