the fuel economy is a very good thing, dont the team drivers use JP motors correct me if im wrong, because like i said mugen has been rippin it up lately. Someone said that the race motors are harder to tune is that tru?
my friend has the novarossi 5 port .12 big $$$ and it is very touchy, if i spent $300 i better not have a problem tuning it.
my first motor was the OS rg .21 for my mbx 4rr and it is fast easy to tune and i have had no problems in two years.
i like reliability
honestly those highend powerful motors are harder to tune and they are more sensitive on needles, one hour turning makes a big difference! so really need to be careful not to carry away expecially on top end needle!
