Features:
The device also can be used as a signal generator forelectric speed controller, then you can test your motor system without using a transmitter and receiver.

There are 3 modes to check servos or Electronic Speed Controller:
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 and test such as 1-3 servos consistency and so on. You can also connect 1-3 ESC to test and compare their reaction time respectively.

It can connect 3 servos of the CCPM helicopters and select servos. It can also connect the servo of airplanes install the steering-box and adjust planes by using such as the neutral mode and so on.

Features:
Can be easily detected and set the dummy bit server, jitter and median.
- Can be connected to two servos or ESC; MCU control, good stability, high accuracy.
Turn the knob, steering can be detected.
If you connect the electronic governor (brush or brushless available), you can get rid of the remote control device for manual control, for testing tone.
Speed ​​or motor performance is very practical, no longer cumbersome connecting the remote control and the receiver.
It is equivalent to a "Hand Dynamic Receiver "feature, playing rudder knob analog transmitters.
