    There is a record already for this aircraft manufacturer including falsifying certification documents, saying that the aircraft had been tested to certain standards etc. but none of this was actually qualified and the required testing was never done. If the testing had been completed then we could make sure the aircraft met certain standards but it seems like it doesn't. From memory and this is going back 4 or 5 years, the claimed centre of gravity position was something like 300 mm rear of where it needed to be. I don't remember the full story in total detail but it was all very dirty at the time.

    I agree with one track, a single aircraft incident, with or without fatalities is unlikely to be investigated by the ADSB. Had the same aircraft run into a house, a preschool or any public building then of course it would be thoroughly investigated (and the pilot, ((cowboy)) in said recreational aircraft) found guilty in record time.

    agreed with red, the pictures on the aircraft show 2 different types of exhaust system which are different from the one you are selling now. Brisbane is hard on motors but it does look like it is pretty old with extensive oxidisation and corrosion on the end of the crank and the flywheel. I'm not saying it isn't brand-new even though the photo showing running, but brand-new means as it came out of the factory. I really do hope it is the perfect engine for somebody's project but in one spot it says it uses 29 L per hour and another spot 9 L per hour. There are a lot of inconsistencies in your listing unfortunately

    Yes, it's shady white Couldnt resist.

    Is the plane epoxy or vinyl ester resins ? The specs are out there for max temps of all the epoxies, dont guess.
  6. FlyBoy1960
    Not sure ? 2CV ? Harley ? not many V's around
  7. FlyBoy1960
    Nope. Never a V twin

    good to hear this information. I had heard production stopped in Japan a long time ago and the engine was no longer being manufactured. Hopefully it continues for some time to come because it is an ideal option now that Rotax have killed off the 2 strokes

    There was a guy at AirVenture about 15 to 20 years ago who did something similar in a Yellow Cub but he also lost an aileron halfway through and managed to fly just as good (or just as bad) with it missing. The first time I saw it my heart missed a beat because I was walking along then looked up to watch the aileron depart and him going crazy out of control, not even knowing he was an air show performer because i had been in one of the buildings. Great days !

    But, the oil is the same mixture whether it comes in through premix or oil injection so it is the same spark plug. (in reality it is slightly different because you use less oil at lower throttle settings with oil injection but it is close enough to need/use the same spark plug)

    the sun will never be above you at the poles ?
  12. FlyBoy1960
    I would like to know if you are standing at the flag at the South Pole which way is South because no matter where you walk you are going north so how could you find your way back home from the South Pole ?
  13. FlyBoy1960
    The smell would be overwhelming
  14. FlyBoy1960
    What a bizzare looking aircraft., it proves engineers will try anything at least once.

    Oil tank hatch

    FlyBoy1960 replied to Red's topic in Skyranger

    you can actually buy these from places like Aircraft Spruce and they come with a template for you to cut the hole and then they just mount from behind either with resin or rivets

    if you go to the listing to have a look they have changed it and now it doesn't start for another 9 days ? https://www.pickles.com.au/general/item/-/details/1995-Jabiru-Model-553J-Light-Sports-Aircraft--TTIS-1398-5/745430/ Item Not Yet Available For Sale Check back soon. Starts 29/05/2024 02:00PM

    Its a factory built "certified/accepted" There she stays, apparently for the rest of her flying days. Would be good if you could do a MARAP (or whatever its called) but i think 55 rego locks you in solidly.
  18. FlyBoy1960
    I have used them in a cub clone and they work a TREAT ! Worth every cent
  19. FlyBoy1960
    Its like calling a Hyundai a Rolls Royce, you can call it whatever you want but its not an LSA which is all to do with certification, standards, paperwork and uses not to mention it doesnt meet LSA flight standards which might interest a newbie and then he/she finds out they cant do what they want with the aircraft.
  20. FlyBoy1960
    I Say Again, its NOT an LSA aircraft, its a 55 registered ultralight. Jabiru might have called it an LSA but its not. It was built BEFORE LSA standards were even published. Call it what it is; and thats a 55 registered ultralight.
  21. FlyBoy1960
    Its not a Light Sport Aircraft a advertised, thats a statutory offence! Its a 55 rego'ed factory built. 430 kgs take off weight is as good as useless. Pass.

    But there is only gravity flow, therefore very low pressure, and significant friction losses. The fuelis only a dribble until it gets to the Rotax fuel pump.
  23. FlyBoy1960
    Uneven feed is due to friction losses in the hose. If the hose from the right tank is longer than the hose from the left tank it is going to generate more friction losses which are very easy to calculate. Also not flying perfectly level will have an effect, if you are right wing down then you are probably going to use more from the left wing and vice versa because the higher tank will effectively have more head in the fuel flow will find the easiest route. Friction losses are significant in small tubes over any distance, an example most people can understand as the water pressure at the tap comes out screaming but at the end of the 10 m hose it is nowhere near the same pressure, this my friends is friction loss. From the Google Multiply the length of the pipe L with the volumetric flow rate Q raised to the power 1.852. Divide this by the pipe diameter D raised to the power 4.87. Divide this by pipe roughness coefficient C raised to the power 1.852. If all dimensions are in metric units, multiply the result from Step 3 by 10.67 to get the frictional head loss. If you're using imperial units, multiply by 4.52 instead.

    Its not the first time RA-Aus has changed or withheld documents for an inquest its been happening for years!
  25. FlyBoy1960
    The names in the report have retired or left before the start of the inquest, Not a good look for the RA-Aus by any means!
