Subject: [LML] Re:=20= Winglets? And introducing myself as a very near future 4p=20 owner.

there are two questions: stability and speed.=20

if you go into the archives you will find comments about both.
My favorite on the speed is in the series of drag reduction articles b= y=20 Fred Moreno:

search the doc for "winglets" and find "side note on winglets"

I don't know what the full argument for stability comes down to=20 aerodynamically.
....is it simply the added span?
I can say that the roll input required with winglets is unpleasant at= =20 high speeds.

careful on the buy.   the airframe could be perfect but still lo= ts=20 of gremlins in the systems.

Hello guys.

I like to introd= uce=20 myself, I am 50, European/American, former Cirrus
SR22 (1100 hours= ) and=20 Velocity TXL5 (250 hours, just sold this plane)
(total 1400=20 hours).

I am a future La= ncair=20 4p owner (looking to buy one these weeks, so if
you know someone= who=20 wants to sell his let me know) and looked at a few
Lancair 4p=20 already.

Now about the wi= nglets=20 (my first question);
Some planes I lo= oked=20 at had their winglets, some not. All those that did not had one told&nbs= p;me=20 it doesn't do anything, the ones they had did told me it works great,
more stability e= tc,=20 even the CAFE report is telling that it produces
more stability a= t=20 higher altitude.

But=E2=80=A6even= the big=20 Charlie Kohler told me it doesn't add anything but more
drag...thus less= =20 speed.

I have no experi= ence=20 whatsoever with the Winglets. So my question to you
guys is, do you h= ave=20 any experience telling you that it does work? (this
is more for pilo= ts who=20 had both so they can tell the difference)

Thanks -- Ronald= =20 Stevens
