A precision brushless motor analyzer that reads KV, RPM, voltage, current, motor timing, vibration and hall sensor function. It's a motolyzer for both sensored and sensorless motors, and its 2x16 character LCD shows live readings. KV: rotor RPM per volt at a given throttle level U (VOLT): input voltage to the checker RPM: rotor revolutions at a given throttle level I (AMP): current drawn at a given throttle level MOTOR TIMING: physical end bell timing, usually 0 to 70 degrees. Rotating the sensor board takes tools. NOISE LEVEL: Bad assembly, cheap bearings or an unbalanced rotor create vibration that hurts performance. Measure it and pick the quietest motor. Phase A, B and C sensor timing shows the real timing of all three sensors.
