Hi Darryl. Interesting figures, very similar to mine. Bottom line we are both AFT heavy. Your C.G with little or none fuel with 2 occupants(approx. 85kg each) is at 466, which is very dangerous especially in a stall situation with no power. Please email me you phone details to firstname.lastname@example.org to discuss further if you wish. As I believe the Jabiru engine mount has been calculated incorrectly - too short. My details - see below;
9.5 hours. Now that is a long non-stop flight. With 53 gallons of fuel, throttled back you can make it half way across Australia. Sounds like you love to explore in your 601, like I do. I can spend hours looking out the window and taking pictures as I motor along. Someday I would like to fly round Australia. I need to rent a 601 and have someone show me around.
You probably made the better choice rather than the Jabiru Australia FWF kit which leaves the builder with lots still to do...
I am looking forward to comparing some performance figures for different types of props on the Jab 3300.
You'll love the plane when you get it flying, climb/cruse performance with the Jab is really good.
Thanks very much, and yes I have changed to a Carbon Fibre ground adjustable prop from Rob Petroni, as the prop supplied by Jabiru was too course in pitch and had me crusing at 120-125knots at 2700rpm. To slow down to a reasonable speed meant running the engine at 2400rpm which Jabiru do not recommend, and to slow down in rough air mean running the engine even slower.
One of the other big benefits is that the prop is much smoother and quiter in flight.
Running 2700rpm now gives me 110kots and somewhere between 18-20 litres per hour. I am still checking fuel comsuption at the moment as I am still playing around with the pitch.
