Per the Phantom manual, your Phantom was ignoring your stick commands since it was below 65 feet. Once it reached 65 feet, it started immediately returning to the home point since you moved the throttle stick as it tried to ascend beyond that point.

So let us say I did regain control by using the left stick, how come it flipped upside down?
I knew I had control again after using left stick, but I couldn't stop the slide to the right at all. My video shows it coming backwards towards me & crashing, but I know from what I saw, that it crashed at the apex of the two roads. That is where I picked it off of the ground. Really weird!

BTW
I used your link to buy from DJI 4 complete sets of the "Real Propellers" plus a spare battery. They had a reduced price sale going on & I can't pass up a bargain!
