The Servo Tester makes easy to check the operation of your servo or ESC without using a transmitter. Once you have this, you'll wonder how you ever lived without it!

The Servo Tester can test the consistency and set the centering for up to 3 servos simultaneously.This is great for anyone who is setting up an RC airplane, car, or CCPM 3D helicopter and would like to see if their servos are actually working or compare the response time of each servo before installing them in there model. Additionally, you can put your servo to neutral/center mode without a Transmitter/Receiver at all.

With 3 modes to check servos or ESC.

• Manual mode: turn the knob with different speed, check the reaction time. 
• Neutral mode: make the servo go back to the neutral point. 
• Automatic "window wiper" mode: make the servo swing like a window wipers in the biggest angle. 

It can connect 1-3 servos simultaneously.
It can connect 3 servos of the CCPM helicopters and select servos.
It can use the electric speed controller (ESC) as a signal generator
