I don't think the X2 lets the retreating blades stall entirely. If that were the case, immediately before stall the retreating blades would be generating something like 25-40% of total lift. The advancing blades would be making up the other 60-75%. As soon as the retreating blades stalled the advancing blades would…

In either case the trailing blades are going to need to increase its angle of attack in order to compensate for the difference in speed. Eventually they will stall. I suppose if you have a higher total number of blades they can be rotating slower to generate the same amount of lift; which might increase the maximum…

A helicopter's forward speed is limited is because the advancing blade generates more lift than the retreating blade. This causes the helicopter to roll toward the retreating blades, and is compensated for by increasing the blade angle of the retreating blades. Unfortunately, you can only do this to a point, and…

I think he revved it up in first gear then didn't shift. When he let out of the gas there was enough engine breaking to lose rear traction.

I have this mill and it works very well; but it takes a surprisingly long time to grind enough coffee for a pot. Perhaps, I am just that out of shape.

I'd be heartbroken if my E36 M3 ended up in the hands of someone like that.
