I want to upgrade a v.2 gearbox, but have no idea what to do lol. The one I'm looking at comes with 7mm bushings, its a m4 long type. I know I don't need high speed... What about high torque? Gearbox shell is a javelin v.2. And I feel like I should hook up the hop unit as well(once again with no idea what to do).
