With the supercubs and Robin DR400s at LGC the tug
wheels are generally on or a little above the horizon.
I wouldn't generally be so low as to be catching the
wake though in strong thermal conditions I can see
that you might. If I tow through a strong thermal
I'm going to release anyway!

It's the position I typically use, so I'm trying to
get an idea of how
different it is from what I normally do. Unfortunately,
I can't go out
and experiment right now, with a foot of snow on the
runway!

So, with a 180 hp Super Cub or Pawnee, say, is the
tug canopy on the
horizon, the wing root, wheels, or maybe the tug is
an entire 'tug'
distance above the horizon?

In mountains it's irrelevant
and different tugs will climb at different rates -
a powerful tug will be more pitched up and adopt a
higher position relative to the horizon than a low
power one (relative to the thrust line, the prop-wash
and the best position of the glider just above the
prop-wash).
