The A6300 High Voltage Brushless Ultra Torque Metal Gear Servo is a great option for Giant Scale, Aerobatic 3D, and Sport Jet models. It is extremely durable, has loads of torque, and is exceptionally fast.
Aluminum servo case helps keep operating temperatures low
Soft start helps prevent component and airframe damage during un-intentional initializations
Over Current and Temperature protection
Helpful initialization start tone lets pilot know when the servo is ready
Integrated servo failsafe holds last known position if signal is lost and power is maintained
Frequency : 200hz to 333hz
The A6300 is the first in an evolving line of Spektrum brushless servos that provide leading edge performance with uncompromised reliability. Boasting an extremely powerful 530 oz-in torque and a lightning fast .10 sec/60° transit time @8.4v, the A6300 will make RC enthusiasts take a second look at Spektrum Servos.
The A6300 features a top of the line brushless drive train that is recognized as being exceptionally strong and reliable. This durability is expertly matched with a low wear, all metal gear train that is virtually slop free. All housed in a heatsinking, all-aluminum case with preinstalled eyelets and grommets, which makes mounting these servos quick and easy.
The Spektrum A6300 uses these features as a foundation to produce a powerful, consistent, yet efficient servo that will prove to be in a class of its own. It is these awesome capabilities that make the A6300 a fantastic choice for giant-scale models, 3D aerobatics, jets or any application where massive amounts of torques and holding power are a must.
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.
