I just remembered, there is a photo of my "stick," complete with tipplets, in my gallery. It's an old photo, since the stick fell out of the sky back in the '80s because someone turned on their transmitter without checking.

This photo shows the plates in the center position, half above the wing and half below. These are quite large when fully above or below the wing. Later, on another plane, I found that smaller ones are still quite effective, especially when they are positioned below the wing.

The ones in this photo would still be effective if the part above the wing were removed.

Here's the link, for your viewing pleasure:
