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.
Years ago (maybe late 1990s) one of those 'whacky invention' type
TV shows featured a guy with jet engines mounted on the tails of
his skis. No need for a chair lift, he'd just ski uphill.
So it has been done, just make sure your life insurance is paid up.

how did he -not- fall on his behind?
get on some skates,tie a rope to your ankles,and have someone tow you,and
see if you can stay upright.
You need the center of pressure to be in the center of your mass.
