Da-2 major modification
The solution is already been designed. It is called the DA-3, the fuselage and wing chord are extended to lower the stall speed or carry more weight (4 seats). There were only two built, one in LA, and another in MI? The LA owner owns the plan copyrights and has the copyrights and plane for...- bob21921

Stall reduction with VG's (vortex generators) for LSA's?
StolSpeed.com tells you where to install the kit on your wing with a template to get the right angles and spacing at 10% wing chord. On a straight wing it's simple, on a tapered wing it's more complicated. -
Stall reduction with VG's (vortex generators) for LSA's?
So your Hoerner wing tips are solid foam with fiberglass? But you could layup a female mold from them now that you have finished wing tips? I really like the look of them, but it still looks like a lot of work. -

Stall reduction with VG's (vortex generators) for LSA's?
Vne is not a consideration at all in Sport Pilot regulations. Vh is the only top speed limit, it is the maximum speed in level flight with maximum continuous power, 138 mph (120 knots) CAS. That is why the Sonex with the Jabiru 3300 can cruise at 170 mph at 8,000' and still be Sport Pilot... -
Stall reduction with VG's (vortex generators) for LSA's?
According to the StolSpeed.com website and testimonials, the VG's keep the air flow attached straight over the wing at high angles of attack using tiny vortex tornado's. VG's never allow it to stall and break, just mush with complete aileron control. It's easy to test, it only takes 5 min to add... -
wing tools and drill
Sonex sells a $5 dimple die that uses your pop rivet gun. The hole would need to match the nail. http://www.sonexaircraft.com/orders/accessories.html -

Stall reduction with VG's (vortex generators) for LSA's?
But the Hoerner Tip molds are already made, it's all time, materials, and profit now. Plus you would be doing a great service to others that want to lower their stall speed. Did you get some fuel in them too? Would they be any cheaper without fuel in them? Maybe Great Planes would sell them for... -
Stall reduction with VG's (vortex generators) for LSA's?
How do you calibrate your airspeed indicator for CAS when it's zero? Is that power on or off? What speed does it indicate on GPS? Do you sell Hoerner Tips for the Sonerai? If so, I want some when I get a IIL project. BTW - Your video above is fantastic! -
Stall reduction with VG's (vortex generators) for LSA's?
I'm looking for a project Sonerai IIL, but I want to know if I can legally fly it first with these mods. I did my research first, but I was hoping to see if anyone had done this before. -

Stall reduction with VG's (vortex generators) for LSA's?
LSA stall speed limit is 51 mph / 45 kts max CAS flaps up Flaps or flaperons won't help at all VG's, new airfoils, extended wingtips, or lower gross weight will $97 VG's can lower stall and approach speeds up to 10-15 mph! -

Stall reduction with VG's (vortex generators) for LSA's?
Has anyone tried to improve their low speed handling and lower the stall speed on a Sonerai? I would like to use Hoerner tips and VG's to fly as a Sport Pilot in the LSA category. http://www.stolspeed.com/content.php http://www.avweb.com/news/reviews/182564-1.html Modified Hoerner Wing tips...
