  1. 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
  2. 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 !
  3. 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)
  4. the sun will never be above you at the poles ?
  5. 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 ?
  6. The smell would be overwhelming
  7. What a bizzare looking aircraft., it proves engineers will try anything at least once.
  8. 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
  9. 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
  10. 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.
  11. I have used them in a cub clone and they work a TREAT ! Worth every cent
  12. 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.
  13. 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.
  14. 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.
  15. 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.
  16. 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.
  17. Its not the first time RA-Aus has changed or withheld documents for an inquest its been happening for years!
  18. 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!
  19. There have been a few used in trikes, including one in a storm down in the Maitland regeon that I remember from almost 20 year's ago. Cant remember if it was HGFA or RA-Aus registered but he took off just ahead of a gust front which caught him out and made his flying uncontrollable. He deployed the chute and landed safely.
  20. I was flying out at the Forbes flat land competition in the 90s Aero towing using an airborne trike. I remember one of these passing me on the descent. He had been up to about 12,000 feet doing temperature traces so they can work out the atmosphere for the days adventure. He would descend past me at over 3000 ft/m almost heading vertically. An amazing aircraft, simplicity but so very well made and perfect for the purpose they were designed for. Certainly not a cross-country machine!
  21. I thought it was Bill Moyes who designed the Dragonfly?
  22. My tinfoil hat uses aluminium made in China, and now all I want to do all day is watch tik-tok. I obviously got Covid twice from the clouds, I was feeling really good and looked up at the sky noticing a dark and ominous cloud and then mysteriously I got Covid twice, double Covid, twice as bad for a man than it is for a woman!
  23. Yes i saw a Jabiru doing the same thing. Smoke trail out the back and then it just stopped and the plane went in silent mode so we couldnt hear it return to base. Something very fishy going on! 🤪
  24. WOOOOOWWWW But the front forks are mounted backwards?
  25. If he is then i am WAY off the track (again) Sorry
