No matter how you scale it, the properties are still the same.

Sorry, for the purposes of this argument, it has to be limited to wheels only. But tell me, with out wheels, how does the prop move forward. If they are turning 100mph due to the movement of the treadmill, how are you ever going to move forward when you can maybe generate 100mph without the treadmill...??

Those pics should stay in the long lost files, honestly. Not something that would be productive today.....but the memories will be lasting til alzheimer sets in.
God bless the Canatard

It will need to overcome any drag induced by an outside source and when the plane reaches V2 it will be off. And safely I might add.

As mentioned, the wheels and their speed have nothing to do with lift. If lift plus thrust is greater than drag plus weight the plan will accelerate until they are equal or climb. And long before the drag of the wheels could overcome the thrust the plane will develops lift which will reduce that drag to nothing. Even a fully loaded 747 can climb at over 500 feet per minute. As soon as the wings start flying the treadmill becomes a none factor.
