I have the Helimax MX400 and I need a 9 or 10t pinion gear. I'm using the Align 430L Brushless and the head speed is way to high even after dropping it to 12t pinion. The problem is I can't find a 9 or 10t pinion anywhere that will fit the 3mm shaft on this motor. So does anyone know where I can find a pinion gear of this size?

11 tooth is the smallest pinion I have seen. It is hard to imagine them any smaller.

Align does make a 9t pinion gear but it only has a 2.5mm shaft which wont fit on mine. I'm thinking about buying that and drilling it out.
