  1. "Sacrificial anodes can work in some situations" That must be why i maintain my good looks, and my wife gets older !
  2. I think it will fly again. It showed on the news the recovery and the wings were in proper wing stands, the fuselage was slung properly by the wing lift points and it was loaded onto a barge and sailed away. The care taken during the recovery leads me to believe it will fly again another day
  3. the powermate regulator has not been available for about 5 years from what I think I remember
  4. I got this YEARS ago, might be some use, dont know if its still even valid/current. XCOM installation in Jabiru powered aircraft The XCOM radio is ideally suited for light aircraft including those powered by the Jabiru engine, there are however some precautions which are necessary to protect your aircraft avionics, including the XCOM radio. The Jabiru engine is normally supplied from the factory with a Kubota regulator. Unfortunately this regulator is not really up to the job of aircraft operations. It is originally designed for use in a garden lawn tractor. In this environment you start the lawn tractor to mow the garden and the regulator only needs to recharge the battery so the next time you go to start the engine the battery is fully charged. In this application and environment the regulator performs really well but unfortunately in aviation use we are simply asking too much from this very basic regulator. In an aviation installation we are not just recharging the battery as we are in a lawn tractor. In aviation we are running radios, transponders, GPS, intercom systems, strobes, recharging the aircraft battery and most of the time also recharging our mobile phone or some other mobile device when we are flying. In this application the Kubota regulator is really going into trauma because it is being asked to perform outside its design parameters. The first thing that happens is the regulator starts to get hot and from there its simply overloaded/overworked and it starts to put out very damaging voltage fluctuations which can be either high-voltage or low voltage. These voltage fluctuations are only for milliseconds so they won't register on a multimeter or a voltmeter inside your aircraft but they will be sufficient to potentially damage your avionics. Items like a GPS with an inbuilt battery tend to be more durable because the internal battery protects the device from these fluctuations, items like a radio and a transponder do not have their own internal batteries and are more susceptible to damage caused by these excessive voltage fluctuations. There are several precautions which you can take in an effort to try and get better performance from the Kubota regulator. Firstly, try and keep the regulator cool. You will notice that the regulator has fins over the top to try and dissipate some of the heat, make sure the regulator is in good cold air flow, keeping the heat down will also help in reducing regulator problems. When you restart your engine after having not flown for some time give the regulator a chance to recharge the battery before you start to turn on all of your additional instrumentation including items which draw a lot of electricity like a transponder and strobe system. Finally, look at replacing the Kubota regulator with a more suitable unit made specifically for aviation use. There are a number of these available on the market from aviation businesses like Aircraft Spruce and others and we also recommend looking at the PowerMate voltage regulator which is suitable for most LSA type aircraft installations. The PowerMate regulator can be purchased directly from our website or from the website of the manufacturer, please visit http://www.powermate.com.au for more details.
  5. Do you mean XCOM ? Try XCOM Avionics Service Ken Luxford 36 Greenstone St, Yarrabilba QLD 4207 Australia Mobile 0412 674 349
  6. contact the company directly and ask them otherwise it could end in flames. If there is no draw on the battery when it is just sitting there it will last at least 9 months before it needs recharging
  7. this is probably representative of the numbers but there are 10 times more Rotax flying then Jabiru's then it is no use in waving your flag. Remember Rotax failures include 2-stroke as well normally although their numbers are in decline.
  8. Maybe the +7 mil in govt grants in the worst unemployment region in AU helped. (to stay in business) before you ask it was in the courier mail
  9. My guess is they will find water in the carb ! Sorry couldn't resist
  10. farming needs to be regulated with the salmonella poisoning in baby spinach. It is obvious that if they had a FSIC ( Farmers Security identification card) then there would have been no poisoning of the baby spinach just before Christmas and also now baby cucumbers. We need to lobby the government to roll out a FSIC card which of course must be renewed every 2 years ! Also, let's make sure they fence off their fields so nobody can get in under the cover of darkness
  11. Horses, no thanks ! https://www.aihw.gov.au/getmedia/b79fc4f1-a447-4e6f-ab76-d5257f4b738f/bulletin24.pdf.aspx?inline=true#:~:text=Although 20 deaths per year,riding participants reported for the
  12. there is some sort of ICAO regulation where if an aircraft registered in the country crashes outside of that countries jurisdiction then it must be investigated by the country where the accident took place. The investigation is reimbursed by the CAA. In this case Australia would investigate the accident, draft up their findings along with an invoice and send it through for payment. This is why you will find 100% of foreign registered aircraft that crashed in Australia have an investigation into what happened. CASA use this as income generation
  13. They investigate every foreign rego because they charge the costs to the other country and make big $$
  14. Yes it shows just how little people really understand, its the most basic part of your training but people just dont understand
  15. Delmar DH20 was meant to be used for medical evacuations where you could put a patient lying down on the back along with a medic. Could fold down for transport one of the big features but the "aircraft" never went into production. I remember this because it was recently used in an e-vtoll presentation showing how far we have come but also remained the same. I think this was in the mid-to late 60s
  16. A biplane that flies a little close to the underneath of a bridge ?
  17. German by the rego so i guess a Bucker Bu 131 Jungmann but not 100% sure
  18. that is a very ugly plane. Huge wingspan at 75 feet doesn't make it ideal for turning around on agricultural strips ? Also not much difference in the performance speeds. Stall 58 kn, Cruise 76 kn to 89 kn. Hardly a real big gap In cruise speed to stall speed. probably a good idea to have be relegated too museums. Thank you for bringing us another very interesting and unique aircraft

    Radios

    Found them, the range is just so NARROW it will cook most radios at either end of the frequency range. Mobile 1 Ground plane independent VHF aerial system

    Radios

    Sorry but these aerials are really TERRIBLE. I have the RF plots somewhere.
  21. Could be because they are flying over the mountain that they suddenly get into huge up winds travelling up the mountain that exceed the G limits of the trike ? that's what it looks like to me and if it is the 2nd time at the same place it would reinforce that there is meteorological involvement
  22. You are kidding ? There are probably more 4-stroke Rotax powered planes flying with IFA and CS prop's than fixed, especially in the past 15 years.
  23. Test pilot for what ? I am sure you will get a little bit more interest if you mention the type of aircraft ?
  24. The same happened to a young Japanese paraglidder pilot who was flying out near Manila in New South Wales. The temperatures were close to 40° and they found her frozen body 24-hours later apparently still rockhard except for the thin layer of skin which had thawed out.
