Key Features

  • Low Cost Servo for 15-25 size aircraft
  • Low Deaband
  • Nylon Gears


 The A4000's lightweight plastic gear train, high-speed and incredible 42 oz-in of torque is ideal for 15 to 25 size glow or electric aircraft. The A4000 is the perfect combination of lightweight and holding power performance at a great price.
Bullet proof analog technology offers an excellent value. Thanks to the low deadband precision this servo will respond and center as closely as possible to that of a high-end digital servo without the high-end price. A single ball bearing supports the output shank to reduce wear and provide a long life of accuracy.
