What if I accidentally double tap the power button, while the Spark already turned on, in a very inappropriate location say inside my office just want to do some adjustment works. How can I abort the launching in only a second or two before the props spining? I presume the Spark will/can successfully pass the face recognition process in whatever reason.
Thanks.

Without doing any testing, the first thing that pops to mind, would be just to turn the Spark upside down.  If the props aren't already spinning, I can't imagine they would start if it was flipped upside down.

If you connect with phone or RC when you enter gesture mode, you can pull down the control sticks to stop the drone.  Or you can let the spark land on your hand. Please inform us if you still have questions.

The safety features on Spark is to rotate it over 90deg. This auto cuts off the rotors.

Thanks. Will give it a try, in open area of course.

Thanks. Will try that in open area to make sure.

You have it in your hand.? Just tilt it to a side, no starting at all!
