So how many of you actually have a working minibot/deployment?

Again, I still cannot figure out this website so I am posting my question here. Many teams have stated that modifying the tetrix gearbox is the way to go, but no one has said exactly what they did to make their own gears, or where they found their own.

So my question is, what exactly do we need to do to make our minibot climb faster? I understand removing weight, adding a gear ratio outside, or modifying the gearbox inside the motor are all viable solutions, but how should we go about doing this?
