Servo Chart

Here's a partial list of the major brands of servos and comparative data (i.e. which servo to use for which kind of plane). These are all the ones I could find on the Internet. I found that a lot of the numbers from different places, including the manufacturers had typographical errors... If you find errors here, send me

Most servo manufacturers make their servos look better by advertising the torque and speed ratings at 6 volts or more. This makes the servos typically stronger and move faster. In the chart below, both ratings are listed (if available). For example:



Servo # Description Weight Dimensions
(W x L x H)
Torque Speed Motor/ Bearings Street Price Notes
94141 Micro Precision High Torque 1.16 oz
(33.1 g)

45/56 oz-in
(3.3 kg-cm)
0.20/0.16 sec
@ 60 deg
Coreless, Single Ball Bearing $59.95  


The torque rating of 45 oz-in is at 4.8v and the 56 oz-in is at 6.0v. Similarly, the ratings of 0.20 sec and 0.16 sec is for 4.8v and 6.0v respectively.

Also, for each different brand of servos shown below, the extremes (weight, torque, speed) are colored in red.
