Hobbywing 30504003 Tunalyzer

Tunalyzer is used to test the brushless DC motor and its internal components. It can measure the Kv value, rpm, current, end-bell timing, and sensor elements of the brushless motor. These parameters can be displayed on the LCD in real time so that you can have an intuitive and full understanding of the motor used.

In addition, the built-in Bluetooth of the Tunalyzer can establish communication with your HOBBYWING ESC through the mobile phone app to realize the parameter setting and firmware updating of the ESC

Bottomline:
Measure motor Current / Kv value/Rpm, End-bell timing / Deviation, Rotor asymmetry, Hall signal deviation, and motor temperature.
Set and upgrade the ESC (which can support the OTA Bluetooth module)
