Micro VG's for elevator?

[Hawkertech]

I was on the Zenith webs site to see what a Zenith 750 stol looked like, and they offer Micro VG's for the elevators. Says it can slow approach and landings even more.

sounds interesting. and from their order form.
MICRO VORTEX GENERATORS for ELEVATOR
Install these new vortex generators on the bottom of the elevator for even slower approach speeds. Kit includes everything you need to install the VGs to a new or existing STOL CH 750.

I’ve got a full set coming for mine. I’ve heard great things about them. Especially on the tail. I tape my elevator gap now and can land tail first. Excited to see how a full set performs.
