Hello Zenair Community
As a new member, a past XL owner, and now building a 601UL in the UK, does anyone have any detailed knowledge on the use of vortex generators on USA 601UL kits?
I am axious to find out 601UL VG stall speed performance and and any affects on ground roll should i choose to fit VG's instead of the european split flaps, which come with the old CZAW factory kits.
Is anyone flying a 601UL with VG's??
thanks you

Thanks Bob. i was aware of the stolspeed site and checked it again after your feedback. I cant find anything on the site, or from Zenair about quantative test on the ultralight 601UL version

I have asked Zenair directly and will continue to search. Thanks again for your help
You need to talk to Viktor Strausak of this site. I read a post of his on this site about the testing he did with vortex generators on his 601. Very impressive results. I believe he is just across the channel from you.
