Didn't Loiter very well - flew away

First flight that did not go very well. Just wanted to see if it would get off the ground then land it again. Ended up landing (not in one piece) 275M away.

Hardware:
S550 Frame
Pixhawk with 3.2.1
3DR GPS
3DR telemetry radio
EMAX 2216 motors with 1045 props
jdrones 20A ESC
Taranis radio system

GPS parameters are default:
FS_GPS_ENABLE: 1
GPS_HDOP_GOOD: 230
GPS_NAVFILTER: 8
GPS_TYPE: 1
GPSGLITCH_ACCEL: 1000
GPSGLITCH_ENABLE: 1
GPSGLITCH_RADIUS: 200
ARMING_CHECK: 1

Took off in Loiter mode, but when it started to take off, changed mode a few times, even tried RTL. GPS fix was good. HDOP under 2.0M.

Vibration may have been an issue, but not certain.

Any pointers would help. Replacement parts are on order (new frame, one motor, and 3DR data radio - antenna busted off)

Looks like vibration fly away from the logs.
The only way to recover from vibration fly away is to switch to Stabilize. You did this too late and with the throttle cut the copter went down hard.

Thanks for the feedback. Next time I may attach a rope tether to the thing, or just get the speed up high enough before takeoff and analyze the vibration.

I keep trying to attach the parameter file but can not attach a file with extension of .param or .txt
