@IRFRANK,
Quote:If the airspeed is above the stall speed, it will fly.
Yes, no, sorry IRF if you misunderstood, it happens often. What I was saying is that the air from the props passing over the wing of a stationary airplane mightily slightly lift it, reducing the friction of the tires against the belt thus permitting them to slip
But there's a lot more to this if you'll review my postings. For instance just how fast the belt is permitted to go hasn't quite been established
"basically to counter rotate at the same speed of the wheels."

Perhaps you did but because it doesn't make sense you forgot it. As I mentioned a couple of times already, it's tautological, like saying "Don's age is exactly how old he is"
