EMAX ES08MA II 12g Mini Metal Gear Analog Servo – 4.8-6V, Futaba/JR Compatible for RC Models
The EMAX ES08MA II is a 12-gram mini analog servo with metal gears, designed for small RC models like helicopters, gliders, and robots. It operates on 4.8 to 6 volts, delivering a speed of 0.12 sec/60° at 4.8V and 0.10 sec/60° at 6V, with stall torque of 1.5 kg.cm (20.8 oz.in) at 4.8V and 1.8 kg.cm (24.9 oz.in) at 6V. The connector is compatible with Futaba and JR receivers, and also works with Hitec, Sanwa, GWS, and most standard receivers.
How fast is it and how much torque does it deliver?
At 4.8V, the servo rotates 60° in 0.12 seconds with 1.5 kg.cm of torque. At 6V, speed increases to 0.10 sec/60° and torque to 1.8 kg.cm. This makes it responsive enough for precise control in small aircraft and ground vehicles.
What receivers are compatible?
The servo uses a standard 25 cm wire with a Futaba/JR-compatible connector. It works with most popular receiver brands including Futaba, JR, Hitec, Sanwa, and GWS. Always check your receiver's connector type before use.
Is it shockproof and stable?
The metal gears and analog circuitry are designed to handle minor shocks and vibrations common in RC operation. The dead band is set to 1-2 uSec, which helps reduce jitter and improve centering accuracy.

Common questions about the ES08MA II
Can I use it in a 1/18 scale RC car?
Yes, many small ground models benefit from the 12g size and metal gears. The torque and speed suit lightweight vehicles.
Does it come with mounting hardware?
The package includes the servo only. Mounting screws and horns are typically sold separately or transferred from your existing setup.
Is it digital or analog?
This is an analog servo, which offers smooth and reliable performance for most standard applications at a lower cost than digital servos.
