Took off today and ascended to about 40'. I then noticed that power seemed low and rate of ascent was oddly slow (in sport mode). Drone then started rapidly loosing altitude and lost all stick control. Resulted in a crash into scrub oak breaking four propellers. Unsure of how to move forward - it seems other issues like this were all over water...

Thanks in advance!

Hi there, we apologize for the crash accident, it is recommended to send in the drone for the evaluation and the data analysis, we will help figure out what happened to the drone.
