whats the differece

[ralliart]

what the difference between a digital servo and a regular servo. i look at some radios and they say that "you must use digital servos for this radio only"

thanks

This is a standard: http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LX0929&P=7
This is a digital: http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXATE5&P=7

The biggest differences are that digital servos are faster, hold themselves better, center better, and are stronger. They are totally worth the money.

Digital servos have a processor in them that checks the position of the servo much more rapidly than a standard servo does. They are not always faster. That depends on the servo motor specs. They just "check" their position faster. That's why with a digital servo, if the car is sitting at a funky angle, like sideways on a jump and just sitting there, you'll here it buzz. Every click in that buzz is the servo repositionsing it's self. This makes for very precise steering control.

Personally, I really don't think it worth the money.

Q. What are the advantages of digital servos?

A-1. Instantaneous response
The digital micro processor is 10 times faster than an analog servo, this results in a much quicker response from the beginning with the servo developing all the rated torque 1 degree off of the center point.

A-2. Programmability
Using Hitec's proprietary programmer and servo test device, model HFP-10, Hitec digital servos can be programmed for, direction of rotation, center and end points, failsafe option, speed and dead bandwidth adjustment. This is great for matching sets of servos for deadband width, center and end points in giant scale aircraft applications and for reversing a digital servo when two are used on a "Y" harness.
For more information on this device, check out: Digital Servo Programmer FAQ.

A-3. Enormous Standing Torque
The standing torque of a digital servo is 3 times that of its analog counterpart.



Q. Are there disadvantages to digital servos?

A. If there is any disadvantage to using digital servos it is power consumption. To obtain the high standing torque and quick response, digital servos require more from the power source than standard servos. By using a larger capacity battery and heavy duty harnesses, you will ensure proper servo performance.

And their price is a lot higher.
