Frequently Asked Questions
Q: What voltage range does this mini ESC servo tester support?
A: This servo tester operates on a wide 3–8V input voltage range, making it compatible with standard 5V setups as well as higher-voltage 2S lithium battery configurations. Please note that 5V servos should not be powered directly from a 2S (7.4V) supply.
Q: Can this servo tester be used to test electronic speed controllers (ESCs)?
A: Yes! Since ESCs are also driven by PWM signals, this tester works perfectly for ESC testing and calibration, in addition to standard servo and brushless motor governor testing.
Q: Can the PWM output range be extended beyond 1000–2000µs?
A: Yes. The board includes solder points that, when bridged, extend the output to 500–2500µs. This wider range allows the tester to drive servo mechanisms capable of 180° rotation.
Q: Is this servo tester compatible with all RC aircraft models?
A: This tester is designed to be broadly compatible with RC aircraft, helicopters, drones, fixed-wing models, and other RC builds that use standard PWM-driven servos, motors, or ESCs.
