I'll bite.
If you were interested in building a Zenith CH-701 (or similar), would you
go for the leading edge wing slats(as designed), or dispense with them and
use vortex generators instead?

That's a pretty big change to make on something so very important. If you
ask me, get a plane plan or kit designed for your intended mission, then
change little things like how high to put the seat.

My greatest fear in making that decision would be to find out you do not
have good enough aileron control at low speed, too high of stall speeds, and
possibly change the center of lift enough to make it out of control in parts
of the flight envelope. You would be a test pilot.

Get a real aeronautical engineer familiar with small planes before you go
with that change, if you ask me.

Thanks Jim.
Its a well-trodden path, with enthusiastic proponents on both sides.

Slats seem to work great within a very narrow window, but with weight, drag, complexity and cost penalties.
VGs seem (!) to do almost as well with little downside.
It difficult to find a definitive answer. Each side seems too committed to their solution to be impartial.

Sigghhh.
I guess I keep looking for builders who've done it.

A- Well there you go. Since this site has been inactive, I had not gone
elsewhere to see this discussed

Interesting. What does Chris have to say on the subject? (as if I need to
askg.)

Let us know what you find out.
