Depends on the receiver and ESC.
Some of my planes, turn of Xmitter and no issue.
One of my planes, turn off the Xmitter and the motor starts up.
The only way to ensure an electric motor doesn't bite you is to disconnect the power.
If you are using a Spektrum RX and the motor starts when you turn off the TX then the failsafe isn't programmed, rebind the RX and it should work correctly. If using some other RX then I don't know.
