I recreated one of those Mustangs, and am currently on my way to Batavia. The first leg proved uneventful, apart from the fact that I ran out of fuel and first could not switch between tanks....but I arrived in Cloncurry at last.
Here's a few pics from the second leg:

The next leg is going to be less interesting I fear..
