I have a 80mm Sage that is in good working order installed in a flying glider. I will sell for $200 and I'll pay the US shipping.

The previous vario I was looking at was ft/ min not knots. Anyone have an 80 mm (3 1/8") Winter Vario in Knots available ?

So, I understand a knot is equal to 101.2 feet per minute, is the requirement due to regulations or a non compromising desire for 'the right scale?
I completely understand either, Just wondering.

Scott,

Normally not a big deal but the flight manual for a Grob Twin clearly asks for a vario in knots.

I've always assumed that using knots for airspeed and ROC was done so
that you can calculate you glide ratio without doing any units
conversion. Once that's done, divide your height by 6000, multiply by
glide ratio and thats your max possible range in NM.

I don't think its that easy if any other units are used for airspeed or
ROC.

Of course, this isn't so important now everybody has GPS navigation
systems that do it for you and draw glide amoebas on the screen.
