Baumgartl PB-60
The Baumgärtl PB-60 was a 1940s experimental single-seat rotor kite designed and built by Austrian designer Paul Baumgartl for the Brazilian Air Ministry. The PB-60 was unpowered and had to be towed to become airborne and fly. It had a fixed tricycle landing gear with a simple unpowered two-blade rotor.Specifications
