Flamewheel F450 with Naza M lite, DX6i, AR7610

I calibrated the GPS after the start up and got the lights signaling it was successful.  I have previously used the failsafe mode and consistently had it land within 2ft of the calibration spot.  My DX6i is set up to toggle failsafe in any flight mode.  So I was flying around showing my co-workers how cool it is and wanted to show them the failsafe mode.  I flick the switch, it increases altitude up to about 60ft and then takes off like a bat out of hell towards my house 4mi away.  I was able to gain control by reverse flicking the switch and swapping to attitude mode before it got too far away.  As stated, I calibrated like I always do and did not get the calibration failure warning.  Anyone else ever have this problem or have any idea what may have caused it?  

Edited for poor grammar

Have you recorded the Home Location by switch S2 unintentional?

the green LED will blinking fast for a while when Phantom record the home location.
The home location record may be triggered when get the enough gps or switch S2.
