Changes stay in the working buffer. Nothing is written to the ESC until you press Write to ESC.

Boot Melody

Pick or paste an RTTTL tune (Nokia ringtone format), Preview it, then Write it to the ESC. Save to Device (Pro touchscreen only) stores it as a preset you can pick on the device. Only the startup melody changes — your motor tune is untouched.

Motor Test — Direction Check

The motor will spin. Connect the ESC to its own motor battery with the motor free to turn — the tuner wire only carries the signal. Use this to confirm which way the motor turns, then flip Direction Reversed if it's backwards.

I understand — arm the test

Test Throttle 20%

Arm the test, then press and hold the button to spin. Release to stop. Requires tuner firmware with motor-test support and an ESC on its battery.

Connect, then press Read ESC to load your settings.
