And in part I do think that we have taken a wrong road with high wing
loading. for example with the Monarch we are able to tow it aloft with 160
lbs of tension at a speed of about 15 mph with a wind down the runway of
about 10 mph. This requires a very small rope and small horsepower.

I'd love to see a winch design that uses a 100hp or less engine,
can be easily bolted on the back of an old pickup, and has engine
and parts that are low maintenance and (especially engine) easy
to acquire (either locally or via shipping).

Alternately, how about a "spare tire" that is really a winch drum.
a stable sturdy "jack" and some way to route the cable
to ensure it winds up nice.

Might not work (thoughts of side loads tipping my car
over come to mind!), but it sure is fun to play with the
thuoght!

Mark,

a 100HP or less winch? What are you trying to launch - kites or RC
gliders? The Europeans are replacing their winches powered
traditionally by Detroit's finest with big rig Diesels, because ...?
Lets get real here. As nice as it sounds to have your own personal
winch in the trunk, the reality looks more like you could haul your
car around with the winch.

But keep the ideas coming.
