The Pfadfinder is in fact a version of the Australian Scout built under licence in West Germany by Mahe.
The Pfadfinder uses a noticeably different wing from the original Scout and is fitted with the Konig SC430 engine. Used at 4400 rpm, this gives 27 hp with a three-blade ground-adjustable propeller. Options include floats, instruments, and a document and map case.
