recieved information on a set of vortes generators for 'Fox wings. At less than $100 with shipping, the price isn't bad. Does any one know anything about Joa Harrison of Harrison Designs LLC that is making the offer?  Take a look at www.landshorter.com.

Hi John,



I think VG's are a winner and that is a good price. 

Only way you can beat that is to make your own.  But

these come with a guarantee!



I bought a different brand and tested them on my Fox

during my 40 hrs of testing.  I tried 5 or 6 different

patterns and did some 50 or so stalls.  I did get a

significant improvement in handling and safety as far

as I am concerned.  I could still completely control

the plane with full aft stick and bobbing in and out

of stalls.  I could even shove in considerable rudder

and not spin out.



Unfortunately I couldn't achieve any siginificant

reduction in stall speeds and need to continue testing

in the future.  As I remember, reporting my testing on

the list resulted in Landshorter jumping in to help. 

I consider that great customer concern and would

support buying from them for that reason too.  They

supported me even though I had a different brand.



I will certainly be going back to testing VG's

whenever I get more time.  Even without a reduction is

stall speed, I like the slow flying qualities.  This

makes me feel much more confident about low speed

landings and that alone would improve safety and short

field work.



Anticipating your question, my cruise speed was

similar with VG's and without.  Some patterns slowed

me down a few mph and some didn't make a change in

cruise performance.



The major shortcoming of VG's to me is cleaning your

plane.  Ha ha.  Ya gotta work around those things. 

Otherwise they are all a plus.

Listening to you guys kicking around stall speeds and slow landing speeds

reminds me of my little escapade with seeing just how slow I could nring it

in on final. I'm down to bringing it over the fence at about 40 when it

stalls about 2 feet off the ground. It didn't drop the nose, flutter or

anything, the bottom just dropped out and I think Charleston Southern Univ.

measured it on their Richter Scale. Back to conservative approaches.

John,

Thanks for this web address.



For all, Check out the "fun" on Landshorter's website.  Some great pictures

of some neat places and planes.



Randy - VG's at some point in the future.

He is one of the engineers working on the new Quest aircraft out of 

northern Idaho. I have a set, but have not installed them yet. They look 

really good, and he said if I don't like them he will take them back. He 

came highly recommended to me from a mutual friend. Professional 

aeronautical engineer and an honest man.

John,

	Joa is a good guy have talked with him several times...   Although more

expensive, we have chose to offer the aluminum VG's.

I received a postcard today from Harison Designs, LLC in Kootenai, Idaho aimed at Kitfox owners and advertising Affordable Vortex generators for $95 per wing.  Needless to say, the claims made sound impressive.  Does anyone in the group have any experience with these, and if so, what is your impression?



Thanks

This is just an opinion...



While the VG's, plastic or aluminum, are going to work essentially the same.

I feel the aluminum is a better way to go.  If you paint the plastic ones

they will most likely last a awhile.. but I know the aluminum ones are going

to.  Also, while the kit we offer http://sportplanellc.com/Wing.htm is more

expensive it also has the instructions, adhesive, tape, video and templates.
