I have about 100 hours flying my P3 when it crashed today. Getting some video of fall foliage, when all of a sudden, after I cleared the tree line height, she was went crazy on me! Banked hard right, my app started saying "atti mode", even though I never hit the switch, went out of sight, I heard the motors revving really high, all I could do instinctively was just increase the pitch hoping she would get higher and I would be able to regain control, but no such luck. I heard it crash onto the street nearby, luckily I didn't hit anything or anybody.
Damage - three out of four of my carbon fiber props were broken at the hub. Found only one of the missing pieces at the scene. Two of the camera gimbal rubber supports were broken, but other two held and gimbal was still attached. Battery ejected. Shell scratched on top and lots of cracks now at the motor mounts. Not sure whether the crash caused those cracks or they were cracked before and thats what caused the crash. I never balanced my props and I'm thinking that may have been the cause? Maybe lost a blade in flight and things went downhill from there? I have no idea how hard it really hit.
Anyway, what's done is done, and am now left with what to do. It powers up fine, and I even put the old plastic props back on just to see if it would power up, all motors sounded good, so I took it up and just hovered it around a foot or two, and it seems fine. So, should I buy a new shell and replace it and fly it again? Can I trust it? Kind of shaken up now. Anything else I should do to get it flying again?
Thanks in advance for all your help out there.

Did you compass calibrate the craft?
Compass note from flight data: "
Found rate of change in the compass of 25 degrees or more per 0.1 seconds.
That's about a 90 degree turn in a third of a second, which is not normal.
This can be a result of extremly strong winds, a crash into an object or a bad compass".
Your trip have compass changes (it's your bird moving/make fast changes) are above 30.2 to 56.5 degree. The maximum "normal" are 25 degree change within 0.1 sec.
This data ended at BAD COMPASS/NOT CALIBRATED.
