Features:

Tiny and lightweight with high output power, this tiny servo is perfect for RC Airplane, Helicopter, Quadcopter, or robot. This servo has metal gears for added strength and durability. The servo can rotate approximately 180º (90 in each direction) and works just like the standard kinds but smaller. You can use any servo code, hardware, or library to control these servos. Good for beginners who want to make stuff move without building a motor controller with feedback & gearbox, especially since it will fit in small places. It comes with 3 horns (arms) and hardware.
