Q. Why does my Savox servo buzz?

A. The buzzing sound is created by the servo constantly making corrections to hold it's position. It is normal with digital servos, but some servos are louder than others.


Q. Can your standard voltage servos handle an unregulated LiFe or LiPo pack?

A. Our 6V rated servos can handle power from a fully charged 2S LiFe pack without any issues. However, you will need a regulator for 2S LiPo operation.


Q. How "waterproof" are your servos?

A. Our waterproof servos are IP67 rated. That means they are "protected against the effects of immersion in water to depths between 15 cm and 1 meter". They cannot survive vigorous motion while submerged. All of our other servos are splash resistant.


Q. What is the spline count for servo horns?

A. Standard and Mini size servos have 25 splines. Micros are 21 spline, and Large Scale are 15 spline.


Q. What size is the servo horn attachment screw?


  • Micro Servos: M2 x 3
  • Mini Servos: M2.5 x 6
  • Standard and Large Scale Servos: M3 x 8


Q. Do I need a "Glitch Buster"?

A. Probably not. Some older Spektrum systems could not handle the current requirements for our servos, but that is no longer the case. Certain combinations could benefit from a capacitor, but test your setup without one first.


Q. Are your servos programmable? 

A. At this time, Savox servos are not programmable.


Q. Can I splice my servo wires for use with a BEC?

A. Nope. Don't do it! Cutting the wires voids your warranty. Buy a servo extension, and make your modifications to that. 


Q. My servo is out of warranty, but I want to have it repaired. Can I send it in?

A. The only serviceable parts in our servos are the gears and case. Since replacing either of those is a simple task for most hobbyists, we do not offer a repair service. 


Q. Why does my servo have "slop"?

A. Our servos come from the factory with no more than .3° of backlash. When using a long servo arm, or in very precise applications, the play might be noticeable. For the vast majority of R/C applications, the backlash will be virtually unnoticeable. Regular "wear and tear" on your servo will increase the amount of play. Replacing the gear set is an easy way to freshen up your servos. The "SA" series servos have minimized backlash from the factory.


Q. What's the difference between "brushed", "coreless", and "brushless" servos?

A. Brushed servos use a traditional electric motor, with a 3 pole rotor, and brushes. This style keeps cost down without compromising quality. Coreless servos still use brushes, but the windings wrap around the rotor like a cylinder, rather than around poles. This lightens the rotor, making it possible for the servo to change directions more quickly. Brushless servos do not have the contact point between the brushes and the rotor, so they are more efficient, and last a very long time. 


Q. Do you offer a continuous rotation servo? 

A. We don't. Each servo is different, so check the spec sheets, but most of our standard size servos are programmed for 100°, with a maximum of 130° via adjustments in your transmitter.


Q. I'm using a Futaba transmitter, and my servos don't work right. What am I doing wrong? 

A. Certain Futaba transmitters have a servo neutral signal of 1310µs, which cannot be changed. Our servos require a servo neutral signal of 1500µs, creating a compatibility issue. These transmitters are as follows: 4FG, 5FG/K, 6FG, 6FG/K, 7FG/K, New Terratop, 3EGX, 3PGE, 2NL, 2LGX, 2FR, 2PK series
