The Valentin "Kiwi" is a light glider from the former manufacturer Valentin Flugzeugbau in Haßfurt .
history
Thomas Fischer from Landshut developed a retrofittable TOP attachment with a three-cylinder König motor with 24 HP and a three-blade folding propeller for the ASW 20 and the Grob G 102 Standard Astir. All drive components including the three-cylinder radial engine König SC430 sat in a gondola at the end of a swivel arm. When retracted, this gondola formed a hump on the back of the fuselage. The drive unit itself weighed approx. 45 kg and could be assembled and disassembled quickly. Valentin, who also manufactured the Mistral-C , planned an aircraft based on the Mistral-C that was specially tailored to the retractable engine . The kiwi should be significantly lighter than the above pattern. So was z. B. the tail boom in sandwich construction like the wings. In this way, the empty weight of the kiwi was only 205 kg compared to 260 kg for the Astir. Otherwise, the aircraft was constructed completely normally and outwardly resembled the glass wing 304 . However, there is no retractable wheel.
