Brass is a bit 'slippery' but will still wear when used with a filled nylon gear. Given the limited RPM/torque it is a good choice for the application. I would not worry about it wearing out the plastic gears.

Ahh ok my thoughts were coming from metal pinions agains plastic / maybe nylon gears on high speed / high torque r/c cars and heard that was a bad idea.
