Text coming on Rgid Wing Models website :

"The Flair was a design developed by Günter Rochelt in 1987. Featured on the cover of 'Drachenflieger' magazine in November 1987, The Flair was first conceived in 1984, but took some time to develop, with work on the fiberglass - Carbon - Kevlar airframe begun in Spring, 1987. After a few test flights, in which the performance was confirmed but the rudders were found to be somewhat ineffectual, Günter decided not to put the Flair into production, concluding that he could improve performance further with some changes to the design (which led to the Flair 30 , whose design goal was to reach a 30:1 glide ratio in a foot-launched aircraft.) "

Text coming from Rigid Wing Models website :

"The Flair 30 was a follow-up to the Flair design also developed by Günter Rochelt in 1987. The Flair 30 first flew in 1990. The pilot could launch by foot, then lay prone in a special harness, and finally land on a skid. After extensive test flights, including more than 50 hours logged by test pilot Knut Von Hentig, the prototype was destroyed in a crash at a sailplane club, when the sailplane pilot flying it dove into the ground at high speed from less than 100 m. Control reversal was suspected but unproved. By control reversal, it might have been meant that the downward-pitching effect of sudden flap deployment overrode the pitch-up of the elevons, rather than the usual kind of control reversal that afflict hang glider pilots flying sailplanes, or vice versa.
Brett Snellgrove wrote in November 2005: "I received an email from an associate of the Flair 30 test pilot. He stated the test pilot felt the glide ratio and sink rate was quite poor, worse actually than modern flex wings. The test pilot attributed this, not to the presence of a hole in the LE as suggested earlier, but rather the pilot positioned over the wing disrupting the flow at the center, most important section of the wing."

1984: Musculair 1 und Musculair 2
http://www.solair.de/
Holger Rochelt
holt sich den Kremer-Preis (Royal Aeronautical Society London) für den Flug über die "Liegende Acht" in vier Minuten und 25 Sekunden.
Im gleichen Jahr stellt er mit Musculair 1 einen Geschwindigkeits-Weltrekord auf und holt sich dafür einen weiteren Kremer-Preis.
Ebenfalls mit Musculair 1 findet 1984 der erste Passagierflug mit einem muskelkraftgetriebenen Flugzeug statt: Holger nimmt seine Schwester Katrin mit.
Die Oskar Ursinus Vereinigung verleiht erneut den Preis für die fortschrittlichste Konstruktion.
Mit Musculair 2 stellt Holger einen neuen Geschwindigkeits-Weltrekord auf und holt einen weiteren Kremer-Preis.
Musculair 1 hängt heute im Deutschen Museum in München, Musculair 2 in der Flugwerft des Deutschen Museums in Oberschleißheim bei München.

1984: Musculair 1 and Musculair 2

Holger Rochelt
gets the Kremer Prize (Royal Aeronautical Society London) for the flight over the "Lying Eight" in four minutes and 25 seconds.
In the same year he sets a world speed record with Musculair 1 and gets another Kremer prize for it.
Likewise with Musculair 1 takes place 1984 the first passenger flight with a muscle-powered airplane instead of: Holger takes his sister Katrin with.
The Oskar Ursinus Association again awards the prize for the most advanced construction.
With Musculair 2 Holger sets a new speed world record and brings another Kremer Prize.
Musculair 1 hangs today in the Deutsches Museum in Munich, Musculair 2 in the Flugwerft of the Deutsches Museum in Oberschleißheim near Munich.
