3-Channel CCPM Servo & ESC Tester

Stop guessing if your digital servos or brushless ESCs are fried before binding your receiver. The 3-Channel CCPM Servo & ESC Consistency Tester lets you bench-test up to three RC servos or electronic speed controllers simultaneously without touching your transmitter. Whether you are centering swashplate servos on a 3D helicopter, testing fixed-wing control surfaces, or bench-testing quadcopter motor responsiveness, this essential PWM signal generator eliminates radio gear from the diagnostic equation. Built for RC builders and FPV bench technicians who value precision over guesswork.

Highlights

• Triple Output Channels: Test and synchronize up to three servos or ESCs simultaneously for perfect CCPM alignment.
• Three Operational Modes: Toggle between Manual sweep, Neutral centering (1.5ms), and Auto window-wiper test modes with a button press.
• Receiver-Free Bench Testing: Acts as a standalone PWM signal generator to test ESC motor drive without binding a transmitter.

Why You Want It

Because powering up your radio, connecting a receiver, and binding just to check if a servo twitches is a complete waste of bench time. Center your control horns, zero your swashplate, and verify motor response in seconds like a sane technician.

3 working modes :
- 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 window wipers in the biggest angle.

Application samples:
Test 1-3 servos at the same time and test the synchronism and consistency of 1-3 servos.
Test 1-3 ESCs at the same time and test and compare the respective reaction times.
Test 3 servos of CCPM structure helicopters at the same time, and use the neutral position and synchronization function to debug the helicopter and servos.
Test the servos on the fixed-wing aircraft and use the neutral function to perform the servo test.

FAQ

Can this servo tester power my servos directly?

No, you must feed 4.8V to 6V DC into the power inputs via a BEC or receiver battery pack; the tester passes this voltage to the connected servos while generating the signal.

What does Neutral mode do?

Neutral mode forces the PWM signal to exactly 1.5ms, locking servos at their exact center point so you can install control horns accurately.
