Greg, Yes, I did mean to say that KRs are certified airplanes. Actually it's a common misnomer. KRs are certified (issued an airworthiness certificate) in the "Experimental Home Built" category. Aircraft such as Cessnas, Pipers, etc. are certified as well, but the correct terminology for them is "Standard Category" aircraft.

As home built (kits) are not certified. About 8 years ago, I had asked if I could put on vortex generators or a cuffed leading edge. And yes, I could put I had not asked in reference to an LSA. It was for improving (shorting) my take off and landing roll. But my guess is that the vortex generators would do the same. A couple of Long EZE's did this very thing and they both said that they improved their numbers. And I would think that VG's would be a lot simpler. As far as the LSA. I don't know what that would do for that. But you could ask your local DAR. Greg Martin I'm not sure the FAA would approve that. I think a "retrofit" would have to be done before the KR was ever certified.
