You said "on top in 2 minutes" and I didn't know what you meant until
I saw the video. On the wire for two minutes! WOW!!! I'd like to know
the details -- length and type of cable? Brand of winch? Altitude
gained?


Makes our winch at the Prescott club look woefully inadequate!

Prescott does very well, IMVHO.


Well, no details yet except that it looks like they got to 1450m. *On
top meant VFR above the clouds, naturally;^)


Puts the whee! in Weedle though.


More info on the websitehttp://www.kac.be/StandardPage.aspx?RID=214


Looks like about 3030 meters of 5 mm Dyneema. *Can't tell details on
the type of winch used or size of the engine.

A nearly 50% height to length ratio is very good.


It isn't possible to use 3000 meters of steel cable - it weighs too
much. Dyneema makes all the difference. It'a opening up a new
chapter in winch launch.

The MEL "Leopard" is a winch specifically designed to use Dyneema
"plastic rope". It's an excellent design.

However, 1450 Meters is not particularly good. Other launches have
gone as high as 1700 meters. They could have gone higher but there
were airspace limitations in effect at 1700 meters.
