I have had very good performance out of my APM 1, I have been flying in stable mode for a short while now and have good control and confidence in my quad.  I flew today and got up to 150 to 200 feet, when descending at about 75 feet I lost complete pitch and roll authority.  My quad went right into the ground bending my motor and breaking the landing gear.  I though the LVA must have been incorrect and took a reading on my 3s1p lipo (3 amp)  and it read 11.5 volts.  I understand that is not with load, but my timer was also on and I was only 6 minutes into flight ( I always get 10 minutes at 1/4-1/2 throttle).  I am very concerned about this as others have noted erratic behavior from this shield/board.  My 2022 kda's each pull 12 amps at half throttle (clamp meter).  My lipo's and esc's get warm but never hot, I fly at 1/4 to half throttle at most.  I live in a rural area and rf interference is not likely.  I am running the latest MP and software.  This really scares me and makes me skeptical about this project using the APM.  I have read numerous reports of erratic behavior by the APM and thought it was user error.  I am by no means a rocket scientist but am not an idiot.   I have experienced great stable flight until now at the same altitudes and conditions.  I am hoping the 200 hundred dollars I saved by not buying a Hover Fly Pro board was worth it.  I am also hoping that there is some error on my part that would account for this.  I request assistance with this issue as I have purchased product from DIYDrones.com

Thank you
