TINSFOS. (there is no substitute for span) The CriCri is 16 feet span. To suggest 14 feet with an engine three times heavier is.... I would start with the Moni and work the span down some. No need for soaring. But for takeoff safety, an acceptable power off glide and low sink rate is still required for such unproven engines. The idea of a sleek but non-soaring sled (short span motorglider) is on my drawing board also. I envision a climb to 6000 feet, shut off the noisy vibrating engine and then do a Luge glide with wild maneuvering for about 20 minutes and land. No thermaling at all.
