FYI Kolb Pilots,

….A GA pilot friend of my Tested VG’s on his Scout…Don’t do this yourself………. He taped the VG’s on only one wing. His wings where well balance prior to test. He tested stalling his plane at altitude. The wing without VGs always stalled first.

Next that he came in low over the runway, in ground effect, and had to use full aileron to keep the wing without VG’s up. Not sure what he would have done if he ran out of aileron? He now flies with VG’s.

As for the question about VG’s on the tail…On U-tube there are some great videos put on by Stlmusic.
If you watch the one call “Kolb in slow flight”. IF I remember the post that was on the list last year, the Kolb you are watching only has VG’s on the Tail.

For what is worth.

Nick:

Your GA pilot friend seems to have less than good judgement.

You forgot to mention a few things in your post:

1-If it took full aileron to keep the VG-less wing up in ground effect, it probably took full aileron to keep the wing up in any part of the flight. How did he do when he climbed up to stall the airplane?

2-Requiring full aileron to fly in ground effect, the pilot would have become aware of this soon as he broke ground, or most likely soon as the mains started getting light. Seems like at this point of the flight, he would have been running out of rudder and cajones.

For what it is worth,

Good Lord John. Why don't you just try the VGs or quit commenting on the subject. Maybe you are just trying to stir the pot and have some fun.
