You should never operate an electric motor in a model without an arming switch. It saves your fingers by allowing you to be absolutely sure you are ready to start the motor.
There are two ways in which an electric motor can be more dangerous than an infernal combustion engine: 1: When an IC engine is running there is a horrible noise letting you know it is running. (This still doesn't stop some people from getting their fingers chopped) 2: It takes a certain amount of deliberate action to get an IC engine running, ie connecting a glow driver, flicking the prop etc. Once you have activated the arming switch on your electric all you have to do is push the throttle stick forward and your stationary prop is suddenly spinning. On my one ESC, just activating the arming switch while the throttle stick is forward starts the motor. Very dangerous! If your ESC did not have an arming switch then simply turning on your receiver would start the motor if the throttle stick was forward. So the correct sequence of starting an electric model is:1, switch on the TX, 2, switch on the RX, 3, wiggle your sticks and OBSERVE, 4, hit the arming switch, 5, advance the throttle.
