Today I was running some AutoPilot Follow missions where my P3S would follow me on my skidoo. I have done many of these missions without incident. I was on my third mission and I was having the AC follow me as I snowmobiled on a skidoo trail. The mission started in a field and then proceeded through a stand of trees. I thought I had had the AC up high enough (30m) to clear all the trees but obviously not as it hit a tree branch and came tumbling down. AutoPilot can adjust for changes in terrain but I chose fixed height because there was not that much of a change in height and I thought I was high enough. This was totally pilot error and my fault.
There was no visible damage to the AC except a scrap mark on the top shell from hitting the tree. The camera and gimbal were attached and appeared undamaged other than being covered in snow. The AC landed in about a 30-50cm of snow and the props were still spinning when I found it. I used a CSC to stop the motors. One prop was completely broken off and another had the tip broken off.
When I got it home and dried it out, I started it up and the camera and gimbal worked perfectly - did its gimbal dance and I had a camera feed. The only problem I am having is that the IMU is requesting calibration. I have tried a number of times but calibration fails. I will try later.
AirData is indicating that I was up at 3268m which is not correct and that the AC was auto landing. The AC was set to be at an altitude of 30m and distance of 17m. I think I got the correct DAT file off the AC, but when I ran it through DatCon and uploaded the csv file to DJI Flight Log viewer, I got an error message.
Here is the link to the Dropbox file, if anyone has time to take a look.

Any ideas on how to solve the IMU problem?
Thanks for any help.
