Ok sick thanks. Yea absolute hobbyz got a lot of the drake novas in stock. They will prob sell them on eBay bidding sooner or later. They did in past but then they set price lower at 200. Yea tom I'm gonna send them a email. Thanks again.

Probably won't be able to find one.

Pretty sure most nova heads would work. Should be able to pick one up off of fleabay pretty cheap.

Yes a C6 is what it probably came with stock.

Thanks
Any recommendations for a pipe in buggy

Herrsavage 10-01-2017 01:21 AM

Don't mean to be pedantic, but afaik RB had their own plugs which were not %100 identical to NR. Nevertheless, the NR C6 is best I think...

bartnz 10-03-2017 05:16 PM

Hi have one also and it's a great engine.
I comes with a #5 so you should be able to get the run in and at least another couple of litres through it (4 litres total or 1 gallon) then go to a Nova #6 TGV offroad plug.
Werks 2058 is what I have been running for a pipe and is great for run time and power.

It has a lot of play in it and I don't wanna blow it up haha. Anyway does anyone know where I can get rb engine parts for this engine. Searched a little but I'm still at track now. I'm trying to see if it's worth replacing the parts or just start using another engine. Any help would be greatly appreciated! Thanks

I haven't been on this forum in almost 3 years.

?????? RB Concepts Gone??????

Today is a sad day.

I need parts for a Worlds S7 and I have a brand new Never fired Worlds S7. What a great product.

Is the New Company RC Concepts taking over the engine line??

RB was made by Novarossi, RC Concept is made by Picco, so there is no parts that will interchange there.
Bearings is usually no problem, but other then that you probably need to search Ebay.

AAAAAAAAAAAAAAaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa gulp...

LOL.. Yeah. Oh well.

Pedro Jesus 04-21-2018 09:45 AM

I have a RB S7 MSC Year 2006
I just hope the engine does not break and lasts until there is no more compression.
Because now there are no more parts to tell you if something breaks.

HaulinBass 04-21-2018 10:27 AM

the novarossi karma and mantra both share the square stroke of the ws7 series not sure of the outside diameter of the sleeve so parts may be available there. the novarossi drake motor is also packing RB parts(its a C5 I believe).
I bet Novarossi has a big stock of parts and we will see a few cheaper engines and maybe some expensive ones carrying RB parts in them.

Quite possibly this can happen or it already happens.
Because Novarossi's stock has RB parts stock they want to sell.
Even on their cheaper motors.
The Novarossi quality is there.

Roelof 04-22-2018 04:41 AM

On the other hand you will have a new Novarossi for the price of a P/S/R set for your WS7 (if you can find something that will fit)

Yes for 200 € or less I get a new Novarossi.
I take the RB Procudtcs complete exhaust from my S7 MSC.

this is old, bu8t how stocked are you???

Herrsavage 04-26-2018 12:53 AM

Anybody want to buy a brand new never mounted RB Blast V15?

Dr. Evil 04-27-2018 06:41 PM

I think the Worlds S7 was purchased in the 90s. I need to check to make sure it's not rusted. . I kept it in a cool place with oil in the engine.

I have the tooling to make the Nova .21 Rod fit the slightly larger crank pin on the .21 RB's

mallee RC 10-13-2018 01:17 AM

Hi guys- need some help- I have a RB BXr sls DI5 and i need a rear engine bearing- I can't see to locate any info on Size- it's Not a 14.5x26x6- they don't have the step down like this does- Thanks in advance

Roelof 10-13-2018 04:47 AM

Ball Bearings for Nitro R/C Engines - NOVAROSSI WORLD

You probably need the 16009
The SLS is the super long stroke and in that time they did come with special bearings.

If you are handy or know someone who is, you can modify the crankcase to fit normal bearings

Rb yuukanai 1 engine tune?
 
Can someone please help bought this awesome engine but not to sure on tuning an no idea where it's at...... where would be a good starting point please if I was to turn it all back to closed. Thank you

PeterEd 10-10-2019 04:22 AM

Just as an update to previous questions on here and to clear something I have been asked a few times, the old RB 01122-C Con rod has now been superseded by the Novarossi 07014 Rod for anyone wanting to rebuild their old motors. This has been mentioned above but i dont think anyone ever gave the part number.

gavalarrr82 04-28-2020 07:04 AM

Afternoon all, hope your all well.

I'm new to this this forum, ive just finsidhed rebuilding my X1CRT pro which has the RB WS7 2 X3 engine. Its been a long time since it last run....maybe 8 years and im wondering whats glow plug to buy and the RB ones are impossible to purchase in the UK. Also unsure whether i need a standard or turbo plug??

Any guidance would be much appreciated

Kyosho Kid 04-30-2020 11:55 PM

nova 6 probably

Jay Dub 05-01-2020 08:21 AM

The WS7 was a Novarossi based engine. Stock, they came with "standard" head, but a turbo head was an option. RB went out of business a while ago, so finding parts isn't easy... However, as far as plugs go, no need, as most standard plugs will fit. Like previously stated, a Novarossi standard "6" plug should be perfect, in colder weather (under 55* F) you might try a "5". There can be allot of other things that will effect your engine, but if you use a "6", it pretty much works all the time...
