take it for what its worth but sometimes glow plug descriptions are a lil out of whack compared to real world testing

i would definitely look at the italian made werks before a taiwanese made engine , many rb engines are not made by novarossi anymore , someone else would know much more about which engines are and which arent

The only RB buggy engines still made by Novarossi are the Buggy10 and Cross10.

What color were the coils of the original plug? Shiny or dull and gray? Dull and gray will still light up but it will not stay hot.

the old plug was shiny and brown, on the surface i dint look at the coils though but all i know is that it was causing flame outs. and i noticed on the, track that it was running like crap with the idle changeing and the low end power feeling soft with the old plug.

my engine was running kind of rich on the low end.

and when i used the, new plug + new filter i was passing people in the corners etc.

Like others have said, a plug can glow just fine and still run like crap. Usually when this happens you can look at the coil and it will appear really dull but sometimes they run like crap even looking brand new. This is especially true if you are running a bit rich, too low compression, to cold a plug or too low an operating temp. These exaggerate the problem.

If it is an older S5, it's a Nova.

well the low end kept on, running rich which i think was because of the old plug not giving me a good idle. soon as i used a new plug, the idle was good and the low end wasnt running so rich.


there was a light smoke coming out of the pipe with the plug.

Most RB's are made by NovaRossi. It's easier to name the few that are not. Like the K9 / K10.

But if you want to start naming the NovaRossi Engines here are a few.

S3/S5/S7/WS7/WS9

Junior 9 / Hobby5 / S9 / B9 / B10 / C6 / Shark / Cross 10

I have s5 with 7 Gallons as a practice motor that runs awesome, idles all day. I just don't use it at bigger events because I can't get the mileage that my Ninja JX21 gets.

Look on RB's website and at amain, the only buggy engines RB still makes are the Killer10, Sport10, Buggy10 and Cross10. The rest are not made anymore.
