I am amazed at how good your videos are and how well edited they are.
You are very presentable for sake of another word and these could almost be part of a series of educational videos with a very presentable presenter
As for cutting the engine completely there are two arguments.
yes the risk factor increases and in these days of a liability society I am torn between practising things for real which will make you a better pilot (if you survive) and the baby flight instructing which happens nowadays!
No spins!!! incipient this and that
I had old time examiners and we would take twins up to 10K and wring the necks out of the things including full engine shutdowns etc.
as I said if you survive you will be a better pilot for it and I am torn between the argument of teaching pilots to fly or churning out aircraft drivers! sadly the leaning is going more towards turning out aircraft drivers not pilots!
