Dear  List: 

Has anyone  installed Vortex Generators on the 601 HDS? I have met a guy from Niagara  Aircraft, a Canadian Co., who says he can furnish VG's for the 601 HDS. This may  be interesting if he is correct. 

Regards,

This has been discussed many times.



Search is your friend. Go to http://www.matronics.com/searching/ws_script_short.cgi , select Zenith for the archive and enter "vortex" for the search string. Using "vortex & HDS" for the search string limits the hits somewhat. Using "vortex & N601RT" will find my post on this subject.

Hi Dick,

In the March/April issue of Zenith Newsletter #153, there was an article 

on Vortex Generators that were added to an HDS.  A few dimensions and 

drawings showing how they can be made.  I remember because the area of 

the leading edge fuel tanks didn't have any.  The claim was that the VGs 

would reduce stall by 5 mph and to comply with performance of LS 

aircraft might have been true even if the regulations as they stand 

would not recognize such an adaption to that purpose.  With a 912 

engine, the 601HDS would fly in ground effect at 35 KTs, and fly at less 

than 40 KTs at full gross.  Said he could not get it to stall with these 

installed.  The aircraft is supposed to qualify for Sport Pilot with 

these.  If you're interested in the article, I can scan it and send it.

Dick,

 I have just installed the Stolspeed VGs from  Australia, but have not been able to fly yet due to weather.  I'm doing the  "experimental" for him.  Will post the results here as well.

 I chose the Stolspeed because they are plastic and  glue on.  Will not cut fingers etc.

Dick:

We installed VG's on our 601 HDS and it reduced the stall speed 6 mph.  The biggest advantage was the increased stability during the landing phase and the added capability of aerodynamic braking after touchdown.
