FREQUENTLY ASKED QUESTIONS

 

Q: How much will vortex generators reduce my stall speed?

A: Conservatively, a 4 to 6 mph reduction in stall speed can be expected. This varies between aircraft
and some of our customers have experienced as much as a 12 mph reduction.
~~~~~~~~~~~~~

Q: Will vortex generators affect my top speed performance?

A: At maximum power, you may experience a 0-4 mph reduction, but this depends on the particular aircraft. 
At normal cruising speed there is no noticeable reduction.
~~~~~~~~~~~~

Q: My plane already flies great. Why would I want vortex generators?

A: Vortex Generators are best known for lowering the stall speed of aircraft. But, in addition, customers
always remark about how much better their planes handle at low speeds and how much more 
responsive their ailerons are. They also feel an extra margin of safety they hadn't experienced before.      
    ~~~~~~~~~~~~~

Q: I've heard of plastic VGs. Do they work as well as aluminum VGs?

A: Plastic vortex generators, even when treated with UV inhibitors, still break down under ultra violet rays. 
They become brittle, break off and fail. Aluminum has been proven and certified by the FAA for
general aviation aircraft and has become the standard to provide a high quality, long lasting VG. 
The stiffness of this material, along with the profile of our VGs, generates the best vortice for 
optimal performance. We've actually had customers remove plastic VGs from their aircraft
 and replace them with our kits. Their performance numbers even improved.
~~~~~~~~~~~~

Q: Can I use aluminum vortex generators on my composite or fabric wing?

A: Yes. the adhesive we provide is compatible with these materials.
~~~~~~~~~~~~~

Q: Do vortex generators increase the weight carrying capacity of the aircraft?

A: No
~~~~~~~~~~~~~

Q: Can I really install vortex generators myself?

A: Yes! We provide the materials and the instructions for you to be able to do your own installation.
