|The Etrich pratterspatz
had a wing span of 20" and was powered by a Telco CO2 motor with a 6cc
tank . The best time achieved by the model was 11 sec. not good enough
for AMA Gas Scale at the time. Problem with the Etrich and most early wings
was the lack of vertical area and the resultant instability when upset
by the slightest breeze, the Dunnes did much better. This photo was recently
published in a German model magazine but I don't know which one.
Carl Hatrack showed it to me last time I was out in Calif.
