well, except for my TNS JP DIRT :0

Today we put some more fuel through the TNS Tuned RC CONCEPT M5C/2046 combo in one of the new guys at my local track in his mugen mbx6 buggy, still on a slightly rich tune, the retun to idle of this engine is amazing and the powerband is very smooth, cant wait till its fully broken in and on a full race tune.

+ YouTube Video

I'm not sure this is the thread your looking for, this thread is for RB Concepts, your running a different engine that the RB engine, the RB's were a Nova Rossi based engine. Yours engine is RC Concepts, totally different. Good luck

Hey savage.. try thr REDS and triton thread.. awsome video other wise...


how are guys here liking the newest line of RB engines? ive never seen them but mabe once or twice here in sydney.. so.. and there is a shop here that has gotten them instock.. curious..

I love mine. They tune a little different than a regular Nova, but once you get used to it, they run great and have great run time!

thought this was the RB thread....not REDS

Summoning old timers please!

Got an old engine to revive my S5 (no, really, the square stroke RB S5). It must be some early engine from RB because I can't seem to find any picture of mention of it. Here's some clues:
-Purple head (in the style of the first S7 but with less fins);
-C5 case like my S5;
-5 port liner with divided inlet port, square stroke like the Sx engines;
-the head has the glow plug button incorporated like the S5.

I'm at a loss here, a purple head RB????

I dropped a new conrod, S5 crank and head and I like how it goes with a 2058 pipe.

Huh?! A CS Sport? Has anyone heard of it?
Paco to the rescue!

i rem that engine, but i think it was short stroke and not square.. I maybe wrong though..

I think it is 16.4 square stroke but will confirm later. Smooth engine and still not tuned to maximum power, the S5/RB 037 pipe was mental when it had a good tune!

Follow up to my woes with the S5-CS engine.
The head bolts came undone and I didn't notice it, no excuse :) but with the only venturi I have here, a 6.5mm, the engine has some poke. The tune is not there but shows lots of potential.
It's a square stroke I can confirm that :)

Hey guys. I have looked through the entire thread, and can't find where I had seen it previously. But would like to know which con rod from Novarossi fits the RB motors. Help is much appreciated. Thanks -J

On top of my head is the R7, which I have now in my S5.

Is the Rally 9 engine Italian or Taiwanese made?

Secondly, if the former, is it likely to be more aggressive than a Blast V15?

(Might offer a trade..)

I see bore and stroke are the same.. Looks like the Rally has the blue front bearing too..

they are Italian, only the killer line of engines were taiwanese, i think...

Yeah, but any other insight as to the differences? The V15 has a double-balanced crank or whatever.. Otherwise they must be pretty similar?
