The company's web site can be found here: http://www.microaero.com/ If you are only talking a couple of mph reduction to get the plane to qualify in ths sportplane category this may fill the bill. The Kits only cost $395.00. Cheaper than rebuilding a wing if time has value. I am interested in your thoughts.

Still,,,,,,, the tabs might have just enough to bring HDS wings into the Sport Plane Category. Perhaps the question should be put to the makers of the Micro Vortex kits.

Save yourself $400 and cut some scrap aluminum strips 1 inch wide and then cut the strips into 1 inch squares. Next just bend the one inch squares 90 degrees in the center, round the leading edge. Then go to the net and do a little research as to the best location for your plane. Tape them on your wing temporarily and try it. If you don't get the desired results move them and try it again (yes we're experimental .... we're allowed to do that). In short save your $400 and spend a few hours of your time and experiment.

Seems I recall a figure of 10% of the wing's cord for an approx location, then angle the VG's around 20 degrees about 1" apart, and a spacing of around 6" between sets. Don't no if they will have much affect on my fat HD wings but I'm willing to give it a try. To be continued .............................

Larry Wood (N701LW reserved) ________________________________ Message 15 ____________________________________ Time: 02:32:51 PM PST US From: Hal Rozema Subject: Re: Zenith-List: VG's --> Zenith-List message posted by: Hal Rozema Another way to stop oil canning of fuselage skin is to paint a 2 or 3" strip of the sound deadening paint that Air Conditioning contractors use to stop the same thing (noisy ducts) in their ductwork. A couple coats, a few mils thick, breaks up the resonating frequencies so that they don't vibrate. In a 701 one can put it on any surface one can reach with a sponge applicator taped to a stick, whilst standing in the access hatch.

Just don't tell anyone it has the speed wings on it. I don't think anybody will be at the airport with a rader gun to check for 2 or 3 mph. Just register it as the HD model. Besides I am sure there are some HD planes out there that were built aaaa... shall we say not so great, off a little here off a little there. And not meet the stall speed but who is going to check? If I were you I would drop the subject and not talk about it any more. After all its your plane it stalls where ever you say it stalls.
