This digital tester from Readytosky lets you bench-check servos and verify ESC throttle response before a flight rather than finding out mid-air that something's off. It drives servos through a range of positions and can sweep ESCs to confirm consistent throttle behavior across channels, which is exactly the kind of pre-flight check that catches a bad ESC or a sticking servo early. A solid addition to any build-and-repair bench alongside a soldering station and multimeter.
