Hi Yenn,
Appreciate your posts but have to reply to your comments above
We did a trip ex Victoria, NT centre, west coast WA and home via Kalgoolie, port Lincoln.
I can tell you truly that the Jab 230 out performed fuel wise better than the C206, Warrior and Technam, and C 172.
Fuel stops planning were mainly to satisfy them when we could have cut our flying time by heaps.
I still have the log if interested further.
Regards.
