I'm reasonably sure that the article is referring to one of the early Lancairs or Glasairs, not to RVs. Some of the older glass airplanes, Lancairs in particular, had some less-than-desirable pitch stability characteristics. If I remember correctly, both airplanes wound up with larger horizontal stabs because the original designs were so pitch-sensitive.
