Okay, So I tried searching this thread but I'm still confused.
I want to pick up a Go 3 port sport. Am I right that you can buy a turbo head button thing and make the motor more powerful?
Where would I get that, and how do you install it? Is it simple?

I basically want a really low price engine to practice my driving, I have an RC8. Getting a 3 port sport with turbo button sounds like the ceapest way.
