This is a really good way to demonstrate the difference that VGs make to the airflow. Notice that outer portion of the wing, behind the VGs, doesn’t stall at all, and the airflow remains attached and smooth. Notice that the inner portion of the wing, without VGs, stalls suddenly and the disruption immediately spreads over the whole portion. But note that the disruption doesn’t spread to the portion of the wing behind the VGs.

Vortex generators (VGs) are well-proven for better low-speed handling, softening the stall characteristics, and lowering the stall speed, which makes it easier to do slower, gentler landings. Stolspeed VGs are streamlined for less drag and better appearance than other VGs. Stolspeed VGs have no sharp points and are flexible, so it's easier to wash or cover the wings. The special 3M adhesive is removable without damaging aircraft paint.

Advantages Stolspeed VGs
Stolspeed VGs have been completely redesigned from all other vortex generators on the market to be much more user-friendly and better looking, while still retaining the aerodynamic effectiveness that vortex generators are renowned for. See Design.

Stolspeed VGs have a very slim rounded fin to give them good flexibility, and a rounded, tapered base that ‘flows’ into the wing surface. They really do look like they’re meant to be a part of the wing rather than a ‘stick-on’. In clear material they’re almost invisible.

Brush your hand over Stolspeed VGs and you can feel the flexibility.
“.....like stiff resilient feathers.....” Other vortex generators are sharp, angular and rigid, and are a real nuisance when refuelling, washing, or covering wings – you wouldn’t dare brush your hand over them!

Вопросы и ответы

How do you know where to install them? How do you know how many to install? Are there installation instruction available for these Stolspeed vortex generators?

Yes, we have added the manufacturer's installation instructions to the "Installation" tab of this web page. Please review them for all available installation details.

Are your VG's UV (ultraviolet) stabilized or protected so sun light doesn't destroy them in short order? How about 3M adhesive, is it UV protected or stabilized?

Per the supplier: The material (Makrolon) used to make the VGs is rated as being UV resistant by the manufacturer. Still, I think it's a good idea to paint the VGs if they are going to be in the sun all the time. The adhesive is very resistant to UV.

Will these be a benefit to a small bi-plane such as a Baby Lakes? Slowing down and reducing stall speed would be a big help on such a short coupled fuselage.

Per the supplier: Yes, I think VGs would have the same effect on such a bi-plane as any other wing. The VGs tend to stabilize the airflow, so that you don't get a sudden stall. So you can hold off to a slower speed and 'mush' on to a more gentle landing.

Are the Vortex generators effective on the rudder at low speeds?

Per the manufacturer: "Experiments with vortex generators on rudders is quite variable. Some report good results but most don't find much effect. At low speeds I wouldn't expect a noticeable effect."

Does the kit come with the template to ensure the correct angle?

Yes, these kits include the templates for proper spacing.

Are the Stolspeed Vortex Generators approved for certified airplanes?

No, these are for experimental aircraft.

Does one set, part # 05-04457, cover both left and right wings or do you need to order two sets?

That kit will do both wings.

Will the STOL vortex generators work on a Vans RV 6?

Yes, these can be used on all experimental aircraft. They are commonly used on Vans aircraft.

m interested in getting some dimensions for some Vortex Generators. Are you able to give me some nformation on the dimensions of the Stolspeed Vortex Generator?

The Stolspeed VGs are 12mm high and the base is 25mm long by 10mm wide.

How would these VGs be applied to a biplane? One wing or both? Top wing only or bottom wing only?

PER THE MANUFACTURER: We do not have any experience with a biplane but VGs on any wing will stabilize the airflow and prevent abrupt stalls, so either wing would show a benefit but both wings would be the most effective.
