Bloody strong engine..

On more serious note. Your cell takes the picture layer by layer from top to bottom. Seems like the prop is turning anti clockwise. Thus each layer is taken that split second later and thus follows the prop through a 90 degree turn for the duration of capturing the prop. Looks impressive none the less.

That was my first homebuilt project. I made most of the metal fittings in my flat in the single quarters in Oranjemund. I flew it for the first time in `80 or `81, I cant remember. It was a lot of fun. I would like to contact the present owner.

Hi All

I have read about these props but have never really seen one. Apparently they were developed in Australia in the late 1920's and early 1930's for use in survey aircraft flying in the Gibson desert. The desert, being largely featureless, played havoc with navigation and the aircraft themselves did not have much in the way of navigational equipment. These props ensured that the aircraft almost always returned to their home airfield.
