IRIS 3DR Toilet bowls/flips after crash

Firmware Version V3.2.1
Uploaded log below.

So, my IRIS took a hard fall from, oh, 100 ft or so. After repairing a broken leg I ran the Mission Planner wizard to reset any possible problems and recalibrate the compass, etc.

The attached log (18-30-03.bin) is an attempt to get the quadcopter off the ground this afternoon. It’s lifting off and as soon as it’s off the ground it spins and flips or just spins.

The log auto analysis reads:
Test: Compass = FAIL - Large change in mag_field (36.40%)
Test: Event/Failsafe = FAIL - ERRs found: CRASH FLT_MODE
Test: PM = FAIL - 14 slow loop lines found, max 13.83% on line 14609
Everything else is GOOD.

However, another log (attached 16-25-15) just before this one reads that the compass is okay.
Test: Compass = GOOD - mag_field interference within limits (9.84%)

I’ve read the “Read First” material about the 5 most common log errors, etc. but frankly am not making heads or tails of the logs.

Any help would be appreciated as this copter belongs to the college where I teach, not me. So, I have to figure this out.
