All low comps are from ex valve, with evidence of lead hammered into the face. OK after a quick grind and back to flying.

Re the dark oil - induction system is ok with clean filters. No induction changes have occurred. This is not on just one plane, but occurred on 3 at similar times. Just hope it isn't one pilot taking a new plane each time and flying with he carb heat on, looking for dust storms!

All air inducted in to a Jabiru engine (in a Jabiru airframe) is filtered, I’m surprised in view of your above posts you didn’t know that

I learned to fly at Navair Flying School at Bankstown in 1970. I remember the Mustangs, operated by Illawarra on the navy target towing contact at Nowra. There was an Airshow at Bankstown around July or August 1970 the two Mustangs and one other (can’t remember the type) had a low level pylon race around the perimeter of the aerodrome, imagine that happening today!

Thanks for the invite, don't think I can do Brooklands tomorrow. I hope we can catch up another time.

How long do you think you will be at YMBD tomorrow? we are flying in from Goolwa probably arriving around 0900. Jabiru J170 and a Tecnam Sierra.

I remember a flight I operated from Hong Kong to Los Angeles via the "flex tracks" which were constructed on a daily basis to optimize the wind, we sat for 3+ hours with a ground speed of 650 knots (150 kts twc)

The strongest wind I recall seeing was on a flight from Narita to Hong Kong in the L1011, I have a photo of the INS wind readout somewhere, was 201 deg/200kts.

My favourite aeroplane, a lovely aeroplane to fly.

Ok.....recently returned NQ....kingaroy......NQ, my jab 160 performed just great.....I noticed infrequently, that my oil pressure guage would fluctuate / flicker, from high in the green, to just in the green markers. Then the odd time it would stay right down just in the green, then after 10......15 mins it would return to it,s normal position up towards the top area of the green.

So......what,s the go here. ( oil levels were checked on route, never below the bottom ref marker on the dipstick )

Welcome to the forum. I completed a course on the Metroliner at the Swearingen factory in San Antonio many years ago, a very nice city, we had a great time.

I have had one on my factory built J170 for about 5 months, I have flown around 35 hours on it and I could not be more pleased with it. The factory say about 3-5 kts speed increase, mine is nearer the upper end. I am told they resist rain very well, and the engine seems to run more smoothly.

The cost of the prop is about the same as a wooden one ($1500) but you have to buy a new spinner and backplate ($300)

The prop is made from black fibreglass, and looks great.
