Looking for a small, well-made propeller for your projects? GWS makes a great series of propellers, and the EP2508 is a nice size for a pager motor!
Didel specially made nice aluminum brackets to fit the GM17 gear motor. Super light for very efficiently built robots!
Here's a really cool quadrature encoder and motor driver for the GM17 Gear motor designed by the micro-specialists at Didel.
