EMAX ES09MA Metal Gear Analog Servo — For 450-Class Helicopters
The EMAX ES09MA combines the smooth analog response of the ES09 series with a metal gear train for significantly improved durability. Designed for 450-class RC helicopters, the metal gears handle the repeated stress of swashplate and tail rotor operation far better than plastic gear equivalents — making it the right choice for pilots who fly hard and want their servos to last. Reliable, durable, and priced for the practical builder.
Metal gear train — significantly more durable than plastic gear servos under repeated heli loads
Analog circuit — smooth, consistent control surface movement
Designed for 450-class helicopters — correct sizing and torque for swash and tail applications
Genuine EMAX quality — reliable performance for demanding helicopter flying
The metal gear upgrade for 450-class heli pilots who want longer servo life without moving to a full digital unit. A durable, dependable analog servo for serious helicopter builders.
