  1. interesting point; maybe <30kg could be saved, so if you wanted lots of endurance, this wouldn't be useful, but if you only wanted to fly for say 90 min, maybe it could work. if you know any well-considered discussions of electric motors in light planes, pls pass this on.
  2. perhaps if I could re-phrase the Q to: weight increase up to 5kg cost increase up to $5000 sticking with petrol engines. Personally I can't ever see a kg of battery ever storing as much energy as a kg of petrol.
  3. how on earth did he "use the controls of the top machine and the throttles of the lower?" I have enough trouble using the controls of just the one plane
  4. I too have owned lots of Japanese bikes. While they were all so much better than a duke in many ways, I don't miss them as much. Maybe that just says something about me?
  5. While it's fantastic to see so many people passionate about wonderful machinery such as Ducatis (and I don't claim they were great from an engineering perspective, merely seductive), it'd be nice to get back to the original thread topic. So I ask all the engineering geniuses out there (this clearly includes everyone who has contributed to this thread) the following question: if the weight of a small plane, eg Jabiru or Rotax powered, could be increased by up to 5kg, and the cost increased by up to $5000, how much quieter could the plane be? Assuming no penalty in terms of safety. These numbers I have plucked out of the air, on the basis of a rough guess of what might be acceptable to many pilots if push came to shove. If you see what I mean. Opinions, anyone?
  6. that's it. Yes, it looks like it was an airstrip once. Those shrubs would make it interesting.........
  7. no, it's not Huntfield. It runs parallel to Sullivan Ave.
  8. I would have too; my 900SS had Conti pipes.................nothing sounds better
  9. I spotted what looks like a strip on the SA Dept of Transport map, and can also see it on google earth. East-west. Does anyone know anything about this strip? thanks
  10. I'm not an accountant, but I point out that (i) the flying club is most unlikely, I think, to be a DGR (deductible gift recipient) and (ii) unless you plan to go into the aviation business in some way, the ATO will look askance at attempts to deduct any flying-related costs. Accountants on this forum will quickly prove me wrong, if I am.
  11. you're quite right, the annoyance factor of noise is often not what people think it is. Personally I would probably find my neighbour's leaf blower far more annoying than if he had a Ducati 900SS.
  12. I agree with this but it doesn't stop local residents complaining and sometimes the local council can be anti-aviation. I don't think the argument that "you bought a house near an aerodrome so you just have to put up with it" convinces many people.
  13. probably very few people would object to such noise, after all these planes fly mainly on special occasions. it's the local resident near a strip who hears light planes hundreds of times a day that get upset by the noise.
  14. from: http://www.adelaidenow.com.au/two-dead-11-hurt-in-burma-plane-crash/story-e6frea6u-1226543395871 an Adelaide woman who survived yesterday's Burma plane crash had this to say: "The wings were ripped off by trees before we crashed which, strangely enough, was a positive because it meant that there were no major explosions as the main fuel reserves were gone. "We were stuck inside for a bit while the plane was burning though, at which point things were not looking great" Sadly there were some deaths, however luckily most passengers survived
  15. I agree, and I think we should all avoid personally derogatory comments of any and every kind. Regardless of how much you might disgree with the poster.
  16. Merry Christmas everyone, and happy landings!
  17. the problems with local residents at strips like Aldinga would mostly go away if the planes were near silent. I can see pressure from regulators, local councils, etc, to make quieter planes. The YO3 shows it can be done, altho' we have no idea of the cost. Looking at the sharp edges on the jabiru prop, and seeing that fancy big paddle on the YO3 makes me think that a re-designed prop might make a big difference. When I was young and silly I had a Ducati 900SS that was very noisy, and I loved the noise. When I got rid of the duke, my family and the neighbours told me how glad they were it was gone. Now that I'm ancient, I hate noise. I'd love the jab to be a lot quieter.

    Brumby 610

    can I ask how much more the 610 cost than a rotax, and how thirsty is it? thanks
  19. wtf??? ah, I know, it's "white tiled floor" in land agent speak.
  20. I should have titled this thread "Alexandrina council......." not Alexandra sorry
  21. This is a great idea, well done. I fully appreciate the work you must have put in. Where are they advertised? they aren't showing on realestate.com.au, as far as I can see Peter
  22. an interesting read: http://www.alexandrina.sa.gov.au/webdata/resources/files/Goolwa%20Airport%20DPA_Nov%202011.pdf
  23. thank you, that is absolutely fascinating. Among other things, they went to huge trouble to silence the engine. I think this could be done much better with little increase in weight (carbon fibre) but it would probably add a lot of cost.
