  1. Well at least we can land on sports grounds, golf courses and roads without power lines in our small aircraft.
  2. This bloke clearly has not done his homework. Who is going to finance an unproven new internal combustion engine when clearly all manufacturers are moving to electric and hydrogen power to meet zero emission standards in the future. Janus trucks here have an electric B double that can get from Sydney to Coffs harbour on a single charge & the battery can be swapped out in 15 minutes while the driver has a compulsory 2 hour stand down period. All he is advocating is another Hybrid & these have been shown to be the worst of both worlds, though Toyota is persisting with them...... for now. He hasn't kept up with battery development. The new Sodium batterys have energy density almost as good as lithium 200Wh/KG and CATL says they will surpass lithium density within 2 years. They also do not require cobalt or nickel & even the LIFePO4 batteries do not require cobalt.
  3. MARAP of course relates only to factory built aircraft but I think the $660.00 fee is over the top and some justification for this fee is required even though it is published as such. I built my own aircraft and so can maintain and modify it as I wish. I installed a new 2 blade Bolly BOS-5 prop in December 2018, completed the appropriate form with the prop data supplied by Bolly and that was it. No fee and my aircraft record is updated so why this exhorbitant fee for doing essentially the same thing. Given the prop being replaced is identical and I imagine is also installed on other Gazelles I can see no justification at all. RA was supposed to make aircraft ownership more affordable but all they seem to be doing is trying to emulate the ridiculous compliance costs of GA. The circumstances surrounding this specific case should see the fee refunded in full in my opinion.
  4. I have a twin piston compressor for inflating tyres. It will inflate a completely flat tyre to 40 PSI in a couple of minutes. It came with a cigarette lighter fitting as well as aligator clips for direct battery connection. I tried the cig lighter fitting & it blew the fuse straight away. It uses about 25 amps. Any mob that thinks their jump starter can be used via a cig lighter socket has rocks in their heads. Don't even think of buying anything they try to sell. There are heaps of jump starters on Ebay from $35.00 to about $300.00. Lots around the $100.00 mark. Check for a money back guarantee and Australian supplier plus customer ratings. The lithium packs are pretty light & they also often have a torch & various USB outlets so can be used to charge your phone, SE2 and other devices. Some also have wireless charging.
  5. Cars usually have them specially made with all the appropriate bends in the one hose. This won't be the case for a homebuilt aircraft unless you have planned everything around the chosen radiator hose. Not my field of expertise but I'd think that you only need flexibility between the engine and fuselage and the rest could be an alloy pipe if there was a longish run.
  6. Who cares when the wings have fallen off.
  7. The alternator on my 3300A engine charges at a consistent 14.2 volts but I would have thought it is the current (amps) that it charges at via the regulator that is more important. Most vehicle batteries are never fully charged by the vehicle alternator. Even after a long run you can put the battery on charge with a good quality intelligent charger like a CTEK MXS-5.0 and it will usually go in to charge mode for a while before deciding the battery is fully charged and switching to trickle or maintain status.
  8. I changed the lot at the time from about .024 to 021. I couldn't believe the difference. It fired instantly once the change had been made. Having one lot at 021 & the other at 024 is an interesting concept. I am not sure how or if it would affect performance or fuel conumption or in fact cold starting. Someone might like to comment if they have tried anything like this.
  9. Anderson plugs should be a standard addition to any amateur build. I had my plugs set for warm weather & woke up on Monday after Airventure in Parkes to a decent frost & the aircraft covered in Ice. The engine would not fire & the battery got too flat. The bloke in the tent next door had one of those lithium jump start battery packs with an anderson plug on it. Stlll wouldn't start till I closed the plug gaps but the little unit was used 3 times. Once warmed up my battery had recovered sufficiently to restart the engine. I have never been tempted to buy one as I'd probably never use it but having the anderson plug with 2 alligator clips in the kit is enough. There are always people around with cars and jumper leads anyway.
  10. From the jabiru Engine Installation manual. 3.3 Ignition • The ignition unit is a dual breakerless transistorised ignition with the magnets mounted on the flywheel and the coils mounted on the alternator mount plate. Figure 11 shows the coils of a Jabiru 6-cylinder engine.
  11. Like all these devices there will be good and bad ones. Anything bought on-line from a Chinese supplier cheap will be crap and have ridiculous specs. One of the guys at our airfield has one and he can start his iO360 with it. I'll ask him what brand & cost. You can't hand prop a Jab engine either. It requres 300rpm to excite the transistorised ignition & there is no gearbox advantage being direct drive. I put a new battery in the other day. The last one was only 6 months old but someting went wrong inside & there was no voltage at all. It was replaced under warranty. I'm glad it happened at the hangar & the battery shop was just down the road.
  12. Trading insults is not what this forum is about. I agree with most of what Bex has said. Morrison took this country down a dangerous road that we are now trying to repair. Youtube sensationalist videos should be taken with a grain of salt till details are verified. The problem is often they never are, so the protagonists get away with it because it suits the narrative of those who support it. China is the worlds factory and produce some of the best products available today, EVs being one of such. There are over 300 EV manufacturers in China making more that 700 different models. China is now the world leader in battery technology. Their platforms are now being used by European EV manufacturers. Battery development to market is occurring at an astonishing rate in China & CATL, the worlds largest battery manufacturer & BYD will be putting sodium batteries in cars this year so if you were thinking of investing in Lithium mines in Australia you may be in for a surprise.
  13. No, both IOS and Android are operating systems and both were originally based on Unix. Both generate GUI (graphical user interface) and commands using gestures. The main difference is that IOS is proprietary and only Apple products can use it. Android is Open Source so the code can be modified by hardware manufacturers & each hardware manufacturer can have a different flavour of the same version. That said it does not alter the functionality of the standard version, they just add stuff to it to try and out perform competitors. When a new version of Android is released phone makers like Samsung, Xaiomi and the other hundreds of brands add their bits to it and they create apps that need their extra functionality. Other App creaters will ensure that their app runs on the standard version so it will run on any brand of android smartphone using that version. Apple make sure they have control to keep prices high and they keep preaching to the converted who often have an almost fanatical loyalty to Apple even though there are plenty of Android phones that are equal or better and a lot less expensive. So Oz runways are telling porkies because they don't have the expertise or development expertise in Android. I have an iPhone SE (2022 model) provided by SES. My own personal phone is a 2017 LG G6 (bought in 2019 for $270.00) The G6 was ranked as the best flagship smartphone available when it was released but LG now don't make smartphones. It is still a great phone now and runs rings around the iPhone SE. Ozrunways need to smarten up ther act because not everyone is going to continue to buy expensive iPads when there are hundreds of Android tablets available with better features for half the price.
  14. Last time I was at Warwick it was pretty cruisy. They have model aircraft & gliders operating & the fencing was very basic (only farm 7 wire fence around most sides) & no gates so ASIC is unlikely to be an issue. LF is $12.00 & parking $12.00 a day after the first 24 hours.
  15. We are about to instal weather cams at South Grafton through Auswebcams. If power is available as well as internet access all you need is a 2 camera system costing $200.00. Annual cost is only data so about $50.00 in subsequent years. If no internet is available you will also need a router, & mobile SIM card & the cost of data upload. Total cost for year 1 is about $440.00 & subsequent years about $200.00. If no power is available you will have to add solar panels and a battery. Cameras/router can run on mains power or 12 volt DC. Photos are uploaded every 6 minutes and are live on Ozrunways, Auswebcams website and Windy. Windy also has a historic stream of the past 24 hours so you can see the weather change data overthat time in a few seconds
  16. I believe that Ozrunways was developed with Apples IOS and the conversion to Android that is called RWY for Android has not been done that well nor is it fully functional. IOS is Apples proprietory tool and while it is good, costs are continuous so everyone pays and pays. Android is Open Source and you can modify it as required and there are no continuous costs. Apple even tried to build in redundancy so you were forced to upgrade when they made older versions of IOS to slow down. Of course iPads are also good quality but expensive. I believe that the Android version of AVplan works well. AVplan is generally preferred by GA pilots. I don't use either. There are a lot of good tablets available for Android. I bought a Teclast P20HD (8GB/64GB now superceded) on line for $180.00 & it is excellent & I have a 256GB SD card in it & have all my documentation & photos on there & room for tons of stuff. iPads cannot be upgraded and do not have card slots.
  17. There are many theories put forward by all sorts of people some with qualifications that on the face of gives their opinion a measure of authenticity. Over 95% of the worlds scientific community agree that climate change and impending catastrophe if not adressed will change the planet so that life as we currently enjoy it will be something of the past. I have not found any that say everything is fine and we have nothing to be concerned about other than those few who have some odd concepts that do not tie in with any verifyable data. After thorough investigation and analysis their theories are always completely debunked. Human need for the resources of the planet to satisfy the ever increasing consumer lifestyle we live is unsustainable. We have used most of the fossil fuel that took more than 3 billion years to create in less than 400 years and pumped all the waste into the atmosphere the land and the oceans. Many continue in their denial and that is their right but it does not give any credence to their opinions especially when they have no verifiable evidence to back those opinions up.
  18. Entrepeneurs keep on striving for never ending growth even though throughout the ages they eventually crash and burn. Environmental damage has not abated even though we know that global temperatures are rising and all the agreements to date have failed. The 1.5 degrees increase by 2100 has well gone and 2 degrees is now unlikely. We will all be dead when it all happens but some may be around to see the tipping point to global catastrophe. There are now over 8 billion of us. There were 2.5 billion when I was born. Growth is slowing but will reach around 11 billion before starting to retract. We have the capacity to deal with it and save civilisation as we know it but eternal greed and quick money over rules sensibility and always has.
  19. An oil cooler is just a radiator heat exchanger. The number of rows, cooling fin size and design, materials used, quality of manufacture, flow rate and weight are all significant issues from an aviation perspective and of course physical dimensions for your build. I chose a 7 row Positech often used in RVs Lancairs etc. It is quite thick and is at the bottom of the firewall with its own NACA duct intake. Works great. Oil temp never gets over 90 deg C even on hot days. I can't remember the cost but it wasn't cheap.
  20. Trevor Jacobs had his licence cancelled by the FAA last year and has pleaded guilty to lying about the aircraft engine failing, staging the aircraft crash, illegally recovering the wreckage and disposing of it. He is facing up to 20 years in Jail.
  21. Does "Northern Australia" double for "Northern Territory" because there is no such named region. AFAIK Northern Australia contains all of NT and QLD & WA above 26 deg South.
  22. So the rudder failed, that is an inconvenience but the aircraft is still fully controllable. All of a sudden there is no resistance on the pedals so the effect is stuff all on the ability of the aircraft to continue to fly albeit a bit out of balance depending on throttle and attitude. Mentally though it has likely thrown a curve ball in to the pilots brain and things start to get out of control from there.
  23. Remember in this situation the young pilot was reportedly at 100 feet and at 78 knots with 25 deg of flap so getting rid of the flap straight away at full power would be the best option. Just put the nose down a bit and fly away. Plenty of speed and altitude & now much less drag. I only flew a 140 twice but from comments here power does not seem to be a major problem but with added drag & high attitude there would be a lot less grunt available than in my old Archer 2.
  24. The battery life is supposed to be 12 hours per charge. I waited for the battery light to go yellow which is 66% of charge before I recharged the first time. I can't remember now how many flights/hours I did but it seemed a long time. Now I just charge it up about once a month as recommended & the charge has never got to 66% since. You can check the state of charge by connecting your phone via wifi & enter 192.168.4.1/stats in your browser. For a club aircraft it will run all day without a problem so just stick it on charge every night like most people do with their phones. You can probably charge the batteries at least 1000 times. My LG G6 phone was new in 2018 & still holds charge for a day & it is charged every night. The SE2 has LG batteries.
  25. Proxy votes in any contested issue are fraught with possible problems. Members get coerced in to making a proxy vote on an issue they know little or nothing about often with devastating consequences. In NSW the Associatoons Incorporation Act was changed in 2009 and made proxy voting illegal unless specifically detailed in the constitution. Most organisations no longer have proxy voting so you must attend a meeting and vote personally.
