Colomban Cri Cri ZK-CRI2 was built by Wayne and first flew on 26/12/08. Wayne has a very interesting blog on building and flying his aircraft at www.cricri.zoomshare.com/0.html However, he advises that the Cri Cri has only flown 12 hours to date and none in the last 2 years as he has had a problem with the right engine failing twice due to seizing of the rear big end bearing. The engines are 240 cc 3W Model motor horizontally opposed 2 strokes producing 22 HP each. Wayne says he feels like he is progressing backwards with flying the Cri Cri, but he also says he is like a "dog with a bone" to identify and solve the problem.
