The A5070 Mini Brushless Servo provides outstanding performance in a mini package. More than just an aircraft servo, the A5070 is great for a wide variety of RC needs, from precision driven 1/12 scale cars to pro-tuned pylon racers.
Allows BECs of adjustable BEC ESCs to be set higher to increase performance
Acts as a heat sink for the motor and ESC
Low deadband, high resolution, with impressive holding torque for unmatched performance
Durable high performance finish
Spektrum high-voltage, brushless servos deliver dependable power and digital precision with amazing efficiency. Finely tuned electronics and software integrate with powerful brushless motor technology to offer ultra-smooth, high-speed performance more efficiently than servos with conventional motors. The all-aluminum case provides the ultimate solution in durability and heat dissipation, while precision metal gears complete a satisfaction package even the most critical pilot can appreciate.
The Spektrum A5070 mini servo uses this solid foundation to achieve a whopping 190 oz/in of torque* and high transit speeds of .07 sec* in addition to its outstanding balance of durability, value, plus the peace-of-mind that sophisticated error correction and over-current/temperature protection offers. It’s an impressive feature combination that makes this mighty servo an outstanding airplane or heli servo choice.
Digital and analog servos have very similar construction and components. They both use the same type of motors, gears, cases, and have a potentiometer. A digital servo is different in the way it processes the incoming signal and converts that signal into servo movement.
An analog servo when it receives a command to move, takes that signal and sends pulses to the servo motor at about 50 cycles per second, which in turn moves the motor to its required position determined by the potentiometer.
A digital servo has a micro-processor that receives the signal and then adjusts the pulse length and amount of power to the servo motor to achieve optimum servo performance and precision. A digital servo sends these pulses to the motor at a much higher frequency which is around 300 cycles per second. This helps eliminate deadband, provides a faster response to the servo motor, smoother motor movement, and has higher resolution and holding power than an analog servo.
There are some disadvantages to digital servos, but the disadvantages are not in any way close to out weighing the advantages. A digital servo will have a higher power consumption (Around 10 to 15 mAh per servo at idle) than an analog servo due to its higher pulse frequency, so larger capacity battery packs are recommended. Digital servos also are more expensive than analog servos which can get very costly in applications that require many servos.
