Readytosky Digital Servo Tester and ESC Consistency Tester

Checking that every servo or ESC on a build responds identically to the same signal normally means wiring each one to a receiver and running the whole radio system just to test one connector, which is slow when several outputs need checking at once. This tester generates its own clean control signal directly, driving up to seven servo or ESC channels simultaneously so mismatched response or a bad connector shows up immediately by comparison against the others.

A 1.18 inch 4-digit 7-segment display reads out the actual signal value being sent, turning what would otherwise be a guess-and-check process into a measured one. Running off a 4.8 to 6V input keeps it compatible with the same battery or bench supply already used for servo and ESC testing, and the compact PVC plastic body (75mm by 38mm by 16mm) is sized for a tool bag rather than a permanent bench fixture.

Common uses are verifying ESC throttle response and motor spin direction before final installation, checking servo centering and travel consistency across a batch, and general bench diagnostics when a build is not behaving as expected and a receiver-based test would take longer to set up.
