I forgot to mention I also had a bad oil leak from between the engine mounting plate and the back of the sump, I had to pull the engine out to fix that.
The rocker bushes were a Jabiru fault the bushes were plastic lined and they started to melt but not only on numbers 5 & 6 which had got the hottest but all of them. Anyway she is running nice now. I cant fault the airframe no problems there she fly's great I love it, wouldn't swap her for quids.
I started out using W100 oil but I think she likes the 15W 50 better. It is a little cooler down here though.
Hi Darryl great to hear from you again, I actually only have one year up so far my first annual is due in a week and a half. I have 70 hrs on the clock.
It has not been all clear sailing though I had temperature problems so I removed the plenum that I had made and installed the fiberglass ducts that came with the engine. The cht's are all good know running in the 140's. Then my rocker bushes collapsed so they supplied me with new bushes and shafts and then I had oil pressure problems, the sender unit was lying to me so I replaced it with a new one and it was lying to me too so I threw them away and installed a mechanical gauge and oil line. With the Aeroshell 15W 50 I am running the oil temp seems to stay around 80 deg.
I flew to Narramine for Airventure and had 115 kts Tas @ 2800 rpm and averaged 16.6 litres an hour for the trip. The engine is running good now so it seems all is finally sorted out.
It's been an adventure that's for sure. How is your plane going?
Thanks for getting back to me Darryl. Thats interesting, my temps are a little high too in the 180s No's 3, 5 and 6 the rest are ok though but my motor is new and I am expecting them to come down a little (hoping).
My motor is late Gen 2 serial no 2529. Your temps sound good now. I will see what happens, maybee keep the fibreglass shrouds in mind.
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 email@example.com to discuss further if you wish. As I believe the Jabiru engine mount has been calculated incorrectly - too short. My details - see below;
These template copies are ready for you. If you want you can email me an address at firstname.lastname@example.org and I will put them in the post. I can also email you some more photos of my installation so you can see how I did it.
I notice you have installed a HACman mixture control, I bought one too when I decided against the TBI throttle body from Rotec. Have you had a chance to try it out yet I would be interested to here your findings and thoughts on its operation.
That's ok, i'll just get to it when I get time. That would be annoying about the Efis though, you spend a lot of money on your panel and still have problems. With my exhaust I am not installing the standard muffler and have the three into one collectors from camit that i still have to weld together with some stainless pipe and bends I bought. Hopefully those joints will suck in a little instead of leaking out, that's my theory anyway. Ether way I wanted to get rid of that big heater just under the sump for added cooling affect.
No worries Darryl. It might take me two or three weeks to get it organised so just leave it with me. I got everything from Aircraft Spruce, rubber baffle part no - 05-00811-3, rivets - 05-00134, I also used some washers 05-56130.
It will be interesting to see how much the temps change with the plenum, I think they will improve though.
My plane will be raa registered, I already have the number allocated, (19 - 8533).
Hey Darryl that fuel burn is unreal, I hope I get those numbers. I have given up predicting when my plane will be finished but I am determined to finish it this year. There's not much left to do, just connect up the engine sensors and tie up some loose ends and then paint when the weather warms up after winter.
If you like I can make a copy of my plenum templates and send them to you. You might have to tweak them a little to fit your plane but they will be close. I think the only don't is, don't make it too tight, leave plenty of room for the rubber so the bottom cowl is easy to get on and off.
Thanks for getting back to me Darryl. I had thought of doing that too but I just thought yours might have been a specific one. My prop is three blade carbon fiber from Rob Petroni at Revolution Rotors, he is up your way. As you know Eddie Seve put one on his Zodiac and was very happy with it.
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.
