How far-fetched is the idea, to use a propeller or jet engine
(radio controlled type?) to push an in-line skater? How does
aircraft takeoff thrust compare to using a conventional motor and
wheel to push oneself along the ground? What sort of incline would
be achievable at say a skater weight of about 160 pounds? I think
the rolling resistance can be assumed to be zero or maybe the same
as a small aircraft.

Anybody know about Everglades/marsh air powered boats? Maybe I
should do a little research on that one.

One thing for sure, if there ever is such a thing as a jetpack, it
will very easily push an in-line skater before it will lift a
person off of the ground.

Thanks.

One thing is for sure it can't be too high or low relative to center
of gravity.
