Even it sounds very good, the top speed of Evo 3 STI is not as that of OS T3

Another:
What temperatures are you guys running the engines?

I see..thanks for sharing the information then. Is the RB Matrix production model already out in manila? I opted to get the Nova Plus 12-3SCT. This engine awsome. Lots of torque also

V1-RRR-WC: So far, I don't have problems with the Kfactory chassis that I'm using. I have been racing it for about 4 months now and still it's in top condition...

I am an old electric 1/10 4wd racer getting back into the hobby. I want to be competitive thats why I chose the RRR Evo.... Thats what most of the guys here run.

I am looking for a good motor that is easy to tune, fast and simple. If you guys can also tell me what hop ups or additional parts might be helpful since I couldnt find the EVO WC.. only the EVO.

Thanks
Well, in my opinion, the OSTZ engines are very easy to tune. Also it's very affordable and very competitive. Somewhat like a budget engine for the budget racer. A friend of mine was using an OSTZ 5ports, ran it like crazy. Didn't replace anything on the engine. Ran about 60 to 65 liters in it until it finally broke down

TO BE HONEST WITH U YOU REALLY DONT NEED ANY HOP UPS FOR THAT CAR, AND FOR THE MOTOR THE STI EVO III IS DEFINETELY A GOOD FAST & RELIABLE MOTOR.

the os tz is not a bad motor but it's also not a balistic motor. parts are pretty cheap though.

I just see it on the track. Maybe OS one is tuned very thin to run.

I have had my EVO2 WCR crank broken, yes, my STI not this issue but till now its not as fast as my OS Speed! Didnt know why..

If crank breaks, would the cylinder and piston be ruined together?
