My gut reaction is the GU has a bit less drag ( without VG’s)and therefore produces 2-3 more miles per hour with a pumped 0200 attached, same rpms and same size props. I’ve flown with both. BTW

The GA(W)-2 airfoil used on the original Glasairs had such a cusped trailing edge, one result of which was an unpleasant stiffening of ailerons at high speeds. You see this, too, in a production P-51,

So with the LS1 canard, how much relief does reflex provide from the stick pressure with sparrow strainers in the inboard position ? Rich T.

Corbin, There is a great two part series in the Dragonfly newsletter titled "Canard Contamination" that covers the history of this subject along with the GU and VGs in-depth. Sadly, determining the

Question: So if the GU airfoil needs VG‘s that cause a little extra drag and the LS-1 needs sparrow strainers that cause a little extra drag, which configuration has the least amount of drag

Now your baby is naked! You’re a nasty boy!!! Is this routine, or is something wrong? Kevin

Sending in my MT prop for a rebuild! Hopefully they get it back to me with enough time to fly it during Field Of Dreams! ____________________________________________________________ Sponsored by

Not much scenery to see here. In fact my RV 6 is butting in on the pic! Ooooh dat waskly wabbit!! Bruce ____________________________________________________________ Sponsored by

Thanks Jim. Oh and if I forgot to update on the VG’s on my GU, I did place them back on and even added a few more on each side. The new ones are white and blend in a bit better than the metal ones

LS1 gotta have em. GU I understand doesn’t. You might not be able to hold on to the stick without the LS1 strainers. Really heavy pressure forward. In fact if the strainers are not dialed in it

Corbin, While the GU canard is a decent canard it had the issues all GU’s have. They are useless in rain or bugs without VG’s as I said to you way back. The LS1 canard is much more forgiving and

Hey Mike, Thats cheating, great view AND a sunset ( or is it dawn ??) Rich T.

Awesome. Thanks. I’m glad to have the GU canard and no sparrow strainer. Corbin -- Corbin N33QR

You nailed it, it's a GU vs LS1 thing. Just one of several reasons the LS1 is a pretty garbage airfoil. Turns out that when used in an area with a control surface the elevator/aileron portion will

Well said Jerry. Martin

DO NOT fly without them.

Good info....thanks Jay. Corbin -- Corbin N33QR

The sparrow strainers on the LS1 are a band-aid. The LS1 airfoil was not designed to have an articulated trailing edge (the elevator). This is because there is a significant under-camber near the

Help educate me on this old topic. I understand what they do regarding pitch, however, why do some of us not have them? Is it a GU vs LS1 thing or is it simply a “don’t have a pitch issue to
