EMAX ES08A II Mini Plastic Gear Analog Servo

The EMAX ES08A II is an 8.5 g analog micro servo with a plastic gear train. It is sized for ailerons, elevators and rudders on park flyers, small foam wings and gliders, and for light robotics or pan mechanisms.

Key features

• 1.8 kg·cm stall torque at 6.0 V, 1.5 kg·cm at 4.8 V

• 0.10 s/60° at 6.0 V for crisp control-surface response

• Runs straight from a 4.8–6.0 V BEC or receiver supply

• JR plug that also fits Futaba-style headers, on a 25 cm lead

• Compact 23 x 11.5 x 24 mm case for thin wings and tight servo bays

Plug it into a PWM receiver output or a wing flight controller servo rail set to 5 V. It is not a high-voltage servo, so never power it directly from a 2S pack. For surfaces that take landing knocks or heavy loads, the metal-gear ES08MA II is the tougher sibling in the same case size.
