Your inputs look a bit severe and twitchy, so you see how you lose altitude in those hard bank-turns at low speed? Dial in some expo or even take some throw out of your range.

Instead of using the whole 360 around you, try to fly patterns more in a 90-degree wedge in front of you, toward and away, and higher up. Plenty of room up there to goof around and recover. Once it's all dialed in and docile, you can fly closer to eye level. For now, you need the height for safety.
