a B11 is a C6..........it is the same as a C5,B10...........they put that same piston/sleeve into piles of engines.....it is indeed a great sleeve design tho.....

I thought so.. Just repeating what people with them have said here..

now that the bx/bxr runs 14.5mm crank,looks like RB are geting rid of old engine parts based on the 14mm crank.

Anybody care to take a stab at how a Blast V14 would compare to the Nvision Race? Have a chance at a deal on the Nvision combo with 2058, new....

the Nvisions are not strong performers, the Blast will be more powerful.....

Well I got some good news and some bad news....
Bad....found out my pinch bolt on my carb was loose
Good....found out my pinch bolt on my carb was loose.
So hopefully that will solve my engine problem.

BTW....it was loose from the factory. :(

That's not at all unusual. Most of the time you have to adjust the angle of the carb to get your linkage in alignment. Some engines come with the carb not installed. Let it be a lesson to do a once over on your engine. Check all screws and bolts to make sure they are tightened.

Hello everyone, I picked up a Kyosho MP9 TKI3 and the guy I got it from had a RB Hobby 9 laying around so he threw it in for me. I haven't ever ran and RB motor. I have a couple questions I'm hoping someone can help me with. Has anyone run one of these in a buggy ? What would recommend as a pipe for this motor ? I would rather have bottom end power than top end. This motor has a standard plug in it, can I swap it out for a turbo plug ? I can find the turbo button for other RB motor but not the Hobby 9. What size venture insert should I run ? I can't anything about that. I found a post about running a 2045/198 pipe and header combo, will that work for more low end versus top end ? Thanks for the help !

Hey Veno,I know your name, probably know your face as well, I raced at One Hobbies, one of they few that ran a Losi 22 and 22T. I'm the guy that always brought to much crap with him to the track ! lol I bought Vareck's MP9. He told me who to talk to about this engine, I don't recall who it was, it may of been you !:D Now that One is gone I'm going to focus on Nitro for a bit. I was at Fear Farm last Friday night running my 8T. Couldn't race on Saturday though :cry:. Anyway, I'm the fat guy, with almost grey hair, stutters, Vareck always made fun of me crashing all the time. You would know me if you saw me. Are you going to race Buggies and Breakfast ?

OK, I was thinking of getting some high-end engine, but couldn't pull the trigger on a Speed, even on a good deal for one.. (Reds R5T combo too..) So I think I'm just gonna' get a Blast. I got the %10 Amain discount, so I could get the V15 from them. OR, I could get a V14 combo with pipe here in Germany for like 20 bucks more.. The V15 though says "14mm dual insert balanced & lightened turbo crankshaft", which I think it doesn't say for the V14.. So is the V15 likely to be the best yet?..

Also, is the RB dust cover thing a no-go or what? I bought one, and mounted it on my P5XLT today, but didn't like how it rotates with the clutch.. Or is that okay?

Herrsavage 09-01-2013 12:35 PM

Anybody know of anywhere still selling an RB Fire(for a decent price..)?

Hi everyone,

I recently purchased a clocked RB blast v12, looking forward to using the motor with a new kit.

However i'm not sure which brand or number i should be going with glow plugs.

I'm running in outside temps that can range from low 30 to high 40s (celsius)with 25%O'Donnell fuel
