The A5030 is the perfect combination of lightweight and high-speed performance at a great price.
It has come to our attention that the metric torque specifications (kg-cm) on the A5030 servo packaging is incorrect.
The actual measure should be:
50 oz-in (3.6 kg-cm) @ 4.8V, 66 oz-in (4.8 kg-cm) @ 6V
The A5030's lightweight plastic gear train, digital precision and incredible .10 transit time is ideal for 25-32 size aircraft. Aerobatic and 3D aircraft that demand performance need the precision of digital accuracy. This servo is ideal and will last the pilot a long time thanks to its tight nylon gear train.
This mini-class servo is durable enough for either glow or electric power applications. Dual ball-bearing support means there’s less resistance to the high output of the high-speed coreless motor. In all these features mean you can expect great performance and long life.
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.
For JR servos we recommend Tamiya ceramic grease (TAM87025).
There are several scenarios which may attribute to this problem.
1. The servo arm fit on the output spline may be loose.
2. There may be slop or wear in the gear train.
3. There may be slop or binding in the linkages.
4. You may have a faulty servo saver.
5 The push rods may be too flexible.
6. Improperly mounted servo (screws too tight, mounting rail too tight against the servo)
7. Faulty extention, damaged lead or dirty connector.
8. Worn or dirty pot.
The frequency on operation is so high that it feeds back with FM receivers.
