The original Larry Renger SkySlash had a pop-elevator that provided negative incidence in the stab. ,The later Estes published SkySlash II, which was the basis for the later Astron Falcon, both were 0-0 negative incidence gliders.

The pop-stab was determined to be too advanced for typical model rocketeers of the time, so it was removed leaving a glider with 0-0 incidence.
