Propeller or jet to push an in-line skater?

Just babbling...

Look up gyroscopic precession - torque induced.

Might also consider tip speeds, and what happens when props
contact things...


Oh, and just on a hunch, I've removed Free.usenet group.

Safety depends on how a device is used. And then there is the fact
that an unbuilt device poses no safety risk whatsoever. A
thoughtful person might consider the possibility of others reading
without being cautious, but how is that a concern when you are
talking about building something.

So put a cage around it. That is what the example from Australia
does.

But seriously. A sixth grader could figure out that one.

There are dozens of paragliding videos on YouTube using a backpack
