The L12-R series of small linear servos operate as a direct replacement for standard rotary servos. They use the same standard 3 wire connector, ground power and control. Regardless of how you drive your servos, be it with an RC receiver, an Arduino board, or a VEX micro-controller, the L12-R servo will function in place of a regular servo, but with the added benefit of providing linear motion.

These hobby grade units are constructed using an anodized aluminum shaft, metal gearbox, brass screw and steel ball bearings. These actuators are built to last and look stylish on your models. 

NOTE: The L12-R will not operate with Futaba receivers like the R6014FS that output 2.7 volts. You will need a Smart Fly Power Expander or Orbit Power Jack to bring the signal level up to 5vdc for the L12-R to operate. 

These linear servos are approved by First Tech Challenge and are compatible with their allowed servo controllers
