EMAX ES3302 12.4g Mini Metal Gear Analog Servo

The EMAX ES3302 is a 12.4 g analog servo with a metal gear train in a slim case about 9 mm thick, made to fit inside the wings of gliders and small RC planes where a standard micro servo is too deep.

Key features

• Stall torque of 2.4 kg-cm at 4.8 V and 2.8 kg-cm at 6 V.
• Speed of 0.12 s per 60 degrees at 4.8 V and 0.10 s at 6 V.
• Metal gears with a dual-bearing output that keeps backlash low over long use.
• Potentiometer feedback for accurate, repeatable centring.
• Universal FUT/JR plug; wiring is red for positive, brown for ground and orange for the PWM signal.

Power it from a receiver or BEC supplying 4.8-6 V; it is not a high-voltage servo, so keep it off 7.4 V rails. For ailerons and flaps, check the wing's servo bay is at least 9 mm deep and allow for the horn swing.
