I did post a comment but he is yet to approve it
Super Video Don and pleased you are OK, I can see your mistakes, first mistake is not knowing airlaw, 500 feet is the rule, but don’t count when you are taking off or landing, I don’t know how the airlaw works in your part of the world but you took off with people and cars at the side of the runway so I would assume the 500 feet rule dose not apply on take off or landing as it is in the UK. turning an aircraft low down is a big mistake, unless you are having fun doing low level turns, you would need to be at a speed far greater than the landing speed. So if you are tuning due to wind low down on landing put on the power and go around.
If you look at the video and pause at 2:10 2:11. you will see you took your right hand off the control bar and put it back on upside down. clearly seen at 2:16 I don't know you but I guess you have 3 axis experience and in the panic you took your right hand off the controls when you knew something was not right, putting it back on upside down your brain will not give the right input to what you wanted. you did stall and crash and this is my reasoning why.
