So... If you're sinking at 1 meter/sec and cruising at 100 km/hr, what's
your glide ratio?

If you're sinking at 2 kts and flying at 60 kts, what's your glide ratio?

How many km per degree of longitude?

How many nm per degree of longitude?

I could go on...

I've used a swivel jack with wheel on my Cobra trailer for 18 years.
Works well, swivels up out of the way for travel, only $30. Go to
westmarine.com and search for "swivel jack".

Eric - Thanks for the comment. The type you describe is the type that
I have now and it is fine. But for various reasons having to do with
space considerations I want the removable type. It seems that here in
the US no such item is used or available (except from glider trailer
parts sources). However, in Europe and elsewhere, it is the
standard. It took me a while to figure out that a "swivel jack" in US-
speak is a "jockey wheel" in Euro-speak. American doing its own thing
I guess - and don't even get me started on why we are the only country
that doesn't use metric (except for Liberia and Myanmar!).
