 else and this means the required control frequency
goes up. A Falcon-sized rocket may only need to correct its course 50 times a
second while a 3-foot scale model would need to do it 10x faster. This means
your sensors need to be faster, your guidance computer has to run faster, and
the actuators have to be able to respond faster.

The hard things on the other side tends to be power requirements, for exactly
the same reason. Mass scales up as the cube of size, including the mass of the
thnigs you have to move. Although you don't have to move them as fast, the net
effect is still that your power requirements become very large for large-scale
vehicles.

He’s such an inspiration. Zero background in any of this and just went “This

That is innovation right there in our faces. All that stuff was theoretically
possible ten or twenty years ago. But completely impractical for a single
hobbyist.

Not to mention that propulsive rocket landing is a thing for -what? Six
years?- in the real world now.
