I'd like to know what causes fly-aways and how to prevent them.
Today I explored the "Receiver Advanced Protection" feature and ran into interesting Phantom Pilot discussions and videos.

CAUTION - DJI NAZA V2 GPS Unexpected Take-Off Hazard – Topic started by Mike Mas.
Be advised if you are using the Naza V2- GPS your machine will take-off with no prior warning - which could result in an accident or serious injury.

Mike's video documenting the hazard:

In summary: When the Phantom's motors start up, the bird will shoot into the air under various transmitter conditions:
* Tx batteries fail (batteries loose - bad connection, dead)
* Tx not turned on or rx doesn't see tx
* Tx stick (A|E|R) off-center over 20 seconds and "receiver advanced protection function" enabled.
* Tx sticks not calibrated. Code sent to receiver: Right stick not on center (A|E|R) for over 20 seconds
* Trims not zeroed (non-stock tx).
* Tx signal blocked - does not reach receiver.

Flyaway Survey TX Type
If you have had a flyaway, Please post what type of Transmitter you were using at the time.
Stock TX, Futaba, JR, Spectrum, ect
http://www.phantompilots.com/viewtopic.php?f=4&t=2433&hilit=receiver+advanced+protection+function
Surprising result: Almost all of the fly-aways were using the stock tx (13)
One person said Futaba TBJ and described the event. Others thought it was an ESC failing during flight.
DJI added Spring-loaded sticks returning to center. This eliminated a lot of fly-aways due to sticks off-center over 20 seconds and "receiver advanced protection" enabled.

Suggest questions related to transmitter used when flyaway occurred.
what type of tx DO they have: stock, Futaba,...
When is the last time they changed tx batteries.
