Just remember...Throttle lock locks the throttle in what ever position the throttle stick is in when the lock is activated.

I had an experience where the throttle lock switch got bumped on while the throttle stick was not in down position, this was during a battery swap so the plane was off, but the radio was still on and transmitting. My plane had a separate arming switch for the motor, which is why I didn't know I was broadcasting a partial throttle position.
Lets just say that when I armed the motor all broke loose. Thank god no one was in front of the plane and that I still have all my fingers! The airplane suffered a lot of damage because it was flailing on the ground trying to spin the prop...smoked the esc too. It took me what felt like forever to figure out how to shut the plane down because I was so fixated trying to turn off the motor with the throttle stick.... Which of course was not even active!!

Now my motor is on the spring switch so it can't get left on, and I use the radios motor timer to delay motor start by half a second before my two second ramp-up to full power even begins. The motor delay timer starts to beep when you first trigger the switch, so there is warning that the prop is about to spin....
