The S256 is one of the smallest brushed motors available with a can diameter of just 3.15mm and weighing 0.28 grams. Suitable for extreme micro experimental builds with either a 20mm plastic prop or a hand carved balsa prop.

This motor with a 20mm plastic propeller will produce 0.44 grams of thrust and pull 0.08 amps.
A comparison of the size of the 3mm S256 motor with the standard 4mm x 12mm motor commonly used with 30mm props. The hand carved wooden prop is 20mm in diameter.
With motor leads soldered to the connectors.
The best way to attach a propeller to this motor's shaft is by using a spacer. Here, we have used a piece of 0.3mm micro pushrod tube which fits firmly over the motor shaft giving a diameter of 0.8mm. The prop can then be pressed on or glued to this tube.

A wooden propeller can also be carved from balsa.
