L^3 is length cubed. The cube of 2 is 8
You are right offcourse, my mistake, 1/2*1/2*1/2 = 1/8

However, wouldn't that mean austins reasoning is even more true?
The shrunk smaller acft will have a higher "density" than the larger one...

So, a smaller aircraft has
- Larger relative weight
- More drag
- Less efficient engines (lower BR)
- Less airspeed (for the same relative thrust)
