Yup. 3 dimensions guys, gotta go through them all. Scale speed can work per say if you have a completely scale environment such as a model railroad layout. It's only good for figuring proper speeds for the environment though and nothing else.

The other thing you can't scale down is the laws of physics such as friction and wind resistance etc. Saying a 10th scale rc going 30 is like a 1:1 going 300 is so far off it's ridiculous.
