The question of wing strength in the KR came up from someone misreading a post a few days ago by a fellow wanting to move to a KR instead of the Zodiac 601 he's currently building. There have been several crashes of 601s attributed to structural failure of the wings due to flutter in the ailerons if the cables aren't correctly tensioned. This builder is now afraid to fly his 601 and posted to KRNet looking for a KR project as an alternative.
