i have the NS12S5. i see not much difference with my STS D5 but pricewise.........................:) :cool:

I have heard great things about the STS motors, I have never seen one run though... How does you nova perform, is it a screamer?

it doesnt scream as hard as RS12S5 but it is fast and running cooler.

Sweet, I cant wait to run my s3... I am sure it will scream. It is sooo tight, one cant turn it over, so I am sure I will struggle to get it going, I know I am going to have to warm it a lot to get it to turn over... It will be a challenge

not really, could be it is NS ! the engine ran in pretty quick. the STS Dragon required much longer run in time

Is it that if a motor takes long to run un, it will last long?

it has some indication but not definite !

whether it last longer or not also depends on how to handle it after run in........

Well, this makes sense. Thank you manticore...

Does anyone know when the new Novarossi Race RX421P engines are supposed to be available?

Has anyone ran the RX421P yet?

www.nitrohouse.com

they have both the 421p & 421b. reviews about the 421b seem to be mixed. i've surfed the web, and found one guy on several boards saying it sucked and he had seen some team guys switching back to the p-5. again, one guy's opinion i've found on different forums. while i was @ nitrohouse, i had asked one of the guys, and he said it ripped. same bottom as the p-5 then pulled from mid to top. so there you go - one engine, two opinions. isn't that the way it always works?:p

I've been running into the same thing.. but, a good source says the engine is very very good

can anybody give me a good setup on a mt12? i can't find a good setup on it.
