We have new reaction wheels at the small and large ends of the spectrum. On the small side is the RW-0.007. With a diameter of 40 mm and a height of 27 mm this is suitable for 3-axis control of Cubesats.
On the large side is the RW-1.00. This reaction wheel packs 1 Nms of momentum storage, and 100 mNm of torque. It is suitable for high performance satellites in the 100 kg class.
See the Reaction Wheel page for more details.
