With a new engine line, and no support.. Are we worried that the quality of the product has hit the crapper?

I really like the RB engines, but if they are not supporting their products in the US/Canada it leaves me a little leary.

My brother has the new WS9 and compared to the B9 IMO it has more bottom end.
The new WS9 has 3 exhaust ports and i don't know how this has affected the power of the engine but it has great power and gets 9-11 minutes with different venturies.

Proud owner of a Junior 9. I feel like a little pee wee with this engine Got it tuned and running.

Has anyone had problems with the pistons breaking on their C6? My original one broke the bottom half off about 3/4 gallon in. I just had the 2nd one blow the bottom off yesterday. One of the guys I race with had the same thing happen to him last season. I thought it was a fluke but now it's happened twice to me. At 180.00 a whack for P/S/R's I'd like to get to the cause of it before blowing the bottom off another one. I did get a good 1-1/2 gals on this one before it popped but I would think this should be a good 3-4 gal. motor with rod changes.

I had a used C6 that popped. But it was used and worth the $125 I paid for it. I put probably 6 gallons on it myself. My C6 I have now I think is a dud compared to the one the piston shattered.

Is it a USA edition? I'm running a WS7 and just got a C6 USA, now I'm a little worried.

Its the same piston in the c6 and USA if that was a question...

I'm not 100% sure, but I bought it in the USA.

i had a wrist pin clip come off of my ws7 with less than 2 gal as i stated in a earlier post and was not able to get any responce from RB. i know ther would be no warranty but i did want to talk with someone. after that i bought a ninja JX and also put a new piston,sleeve, and rod in the ws7. now the new piston skirt has broken off on one side again with less than 2 gal.ran through it. i am very happy to report that the mugen ninja JX is running very strong and i plan to never purchase another rb product. i also think if i wanted to sell and support a high end engine line for rc racing i would spend a little time each day looking on rctech to see if i could help my customers even if i didn't like answering my phone and emails.

Well put! I don't blame you and couldn't agree more!

I havn't had any problems with my WS7 at all, it's just getting a little tired.

Lmao!

hey guys i need some help i got a rb engine in a trade i just did but im not sure what rb engine it is i was told it is a RB concepts .21 3+1 port CE engine can you guys give me any feeback on it is this a good engine ? its got about 1 gallon on it so ive been told feels like its got good compression anywho here are some pics can you guys help a fellow racer out thanks alot.

Ive got a new hobby 9 that i just finished breaking in using the heat cycle method. After about 30 minutes worth of heat cycles(letting it cool to room temp at bdc between cycles), i slowly started to tune it. Now ive got around 60 minutes of total run time on the engine. Its got great compression, but the pinch is almost already gone. My GRP had a tight pinch for the entire first gallon. Is this normal for an RB, or did i do somthing wrong?

The head looks like what RB used to cal the S7 Europa, they were just like the worlds S7, without the coated crank, black engine case, and rody rod.. They ran well. Had several over the years.
