Скачать или смотреть FPV Drone Keeps falling out of the sky!! Unknown Reason

I have been having some issues with my drone the last few days! As I am flying around thinking everything is going good, my drone drops out of the air. I have no idea what would be causing the issue. In the video you will see several times that i caught this on video. There were many other times this same exact thing happened that I was not able to catch on video.

First set of Clips:
I was running Cobra 2207 2400 kv Motors. One broke and I switched out all the motors to EMAX Special Ed's White 2450 KV.

Race Course Clips:
Only difference in the quad was the motors I switched.
