LOL!

agreed!

last year we towed the Tetra15 out to a mountain airstrip to do some late fall flying. On the way back my buddy flying the Colt towplane had it firewalled and I caught up and passed him. The air was smooth a silk and I was going as fast as I had ever gone in the ship............it was a great opportunity to expand the speed envelope. We have all the control surfaces mass balanced and the ship is incredibly torsionally stiff.........bet it would go faster....game on!

Seriously, none of the Winter ASIs come with 0 to 120 knot scales. In fact this is one of few ASIs that does. It seems very easy to read and the price is good. Does anyone have any comments on the brand (Skysports)?

The Winter ASW-27 ASI goes to about 160 kts. the arcs are of course calibrated for the ASW-27. for my homebuilt, I've tested it for a VnE of 135kts, so the arcs need to be changed accordingly. who knows, this glider may go to 160kts, but do I really need to go that fast?

YES!

Just a bit of advice. Do NOT get an airspeed indicator that has its max range limit at your plane's redline. Why? Do you really know if you are at redline or maybe 20 knots past it if your indicator hits a stop (either visible or not) at your indicated redline?

As UH says, FWIW.

Dsve Lawrence (PIC in the aforenoted NTSB report) wrote up the accident for
AW&ST (Aviation Week & Space Technology) and Soaring magazine (online archive
available). I know and have soared with Dave (former Libelle/ASW-20 owner),
and shared more than one post-camp-flight B.S. session with him. Good
pilot/person/guy. He has an extensive background in (manned and unmanned)
flight test, flown military aircraft, and IMO is very much a 'switched on'
pilot, with no obvious "I am God-personified" in his pilot attitude that I
ever sensed. Yet he was fortunate to not lose his life in this 'he screwed up'
accident. Human perfection isn't an option...

Also, "What Steve L. said."

Also also, FWIW...

Are you kidding me? I think anyone can tell when going 100 knots or 20 knots.
Slow down! Who wants to go over 100 knots? Not me.
I have no idea what FWIW means, nor do I care. YIMMV
