This Flite Test Servo Tester allows you to set up, test, and center up to 3 servos at once! With an input voltage of 4.5-6V, most BECs found on Flite Test & EMAX escs will be an ideal choice to power the tester. Lastly, this tester incorporates three separate functions: automatic (full sweeping motion), neutral (for installation of servo horns), and manual (controlled by the dial). 

An ideal choice and perfect tool to have in the hobby room, field box, or radio box!

To use:  

• Add 4.8-6.0V power source into right port
• Plug desired servo into left port 
• Use selection button to toggle between modes
