  1. I like the design principle of the D-Motor in that the valve design isn't interference. Its a side valve. I was drooling over this 115Hp lycosaurus experimental which apparently still doesn't benefit from electronic fuel metering 233 Series
  2. Here (post #37) we have yet another example of someone arguing with maths. Please don't because its embarrassing. Anyone who thinks a motorcycle idling away on the side of the road charging a battery for some traffic cop 10 hours a day is representative of an aero engine application, please start a club of your own or something. Actually, scratch that. @fly_tornado please do tell us here how many thousands of trouble free hours your flying motorcycle engine has accumulated since 2010. Surely that's enough flying time to be able to give a representative real world example?
  3. I have about half my hours behind or in front of Rotax engines. I didn't express an opinion either way
  4. The maths is in the mean piston speed. A piston with a 2 inch bore is travelling 4 inches every revolution. The 2.4 inch stroke Rotax 912 continuous setting of 5,800 rpm yields a mean piston speed of 11.8 m/s The continental O-200 has a 3.88 inch stroke which at 2400 rpm yields a mean position speed of 7.88 m/s which is about 2/3 of the Rotax. TBO for the Rotax is between 1500 and 2000 hours, the O-200 is 1800 hours. They are apples and oranges so the numbers really only start a new argument rather than informing an existing one. Compare this to the speed of sound which is the maximum speed a flame can propagate in the absence of detonation ~350 m/s and it clear these pistons are moving relatively slowly but changing direction a lot. @fly_tornado the mean piston speed of a R1150 at 6000 rpm is 14.1 m/s. To get the same piston speed as the Rotax the engine would need 5000 rpm. It's not going to be a problem with your application because the engine will only see light and very occasional use.
  5. For those watching The the automotive archaeology is fascinating. Those crispy 15 year old wiring looms look ... interesting. There are now connector replacement kits for common GM and Ford looms where the connectors go to the injectors and ignition.I remember reading somewhere (two wheels magazine?) that air cooled BMW flat twins don't appreciate being stored and tend to eat their main and big end bearings when left for more than 6 months without a bit of oil circulation or some proper engine pickling. I have no idea why (new oil doesn't seem to help) and I've never tested the concept. I have a strong suspicion that the aero engine makers and the goop makers got this issue sorted a long time ago. I am aware that this thread started in late 2010 and the engine could have been new in 2004. Is there is a good chance the OP engine hasn't run since then? Given the bun fight I got into with the Bavarian Money Waster stealership over a clutch cable 6 months after the R1100 I owned was obsolete, I am very interested to see how much support BMW Australia has for something over 10 years old. For the record, the dealership broke a head stud, charged me to fix it then gave me the keys to a NSW Police K1200. When I told them the key didn't fit, this was the reply in the stealership show room: "HTFU and turn the key harder" because they already broke the lock for me with it. I kept the key and left the bike with them until NSW Police complained. Shortly after that incident they lost the Police MRO contract to another provider who was equally bad in a different way but that is a story for another bedtime. BMW Australia said "how bad for you, do let us know how you get on". I am not over BMWs. I am over the Ming Mole retail non-service that comes with the product. I tend to ride stuff I can fix myself for that reason among others.
  6. I bet I still can't get it to follow me home and it has no trailer
  7. My opinion is that when everyone has a good job, aircraft prices don't go down. When good jobs and flying hours take a hit like they did ~10 years ago, people are more keen to say goodbye to their toys. There is also a value second hand relative to the value of new replacment especially in the case of aircraft which explains why a 1977 Cessna 172 is holding its price quite well after the SIDS are done. A 19- registered drifter or fisher koala with a new engine and new wing skins should be worth at least whatever those parts are worth retail plus a margin for the general condition of the rest of the aircraft. If the aircraft is common, easy to fly and easy to maintain it should be easy to sell. Ask FlyerMe! As usual, a sale goes through at whatever price the buyer and seller negotiate. I suspect at least one Corby Starlet has changed hands for not much more than the outstanding rental fees on the hangar it was stored in
  8. Post 2 and 3 you are both right. 24- 25- and 55- registered aircraft (e.g. Factory built, fee-for-service maintained ... Have a look at the regs) are examples of aircraft that are commonly used for flight training where the person receiving training doesn't own the aircraft. When flying a 19- registered aircraft, it's between the owner who is receiving the training and the instructor to decide that the aircraft is suitable for the instruction being undertaken. For example, is everyone ok if there is only one set of controls? Of course if you are the instructor and the plane ends up in a report, there is still a lot of paperwork. I have many examples where it's come to this for a 19- aircraft so training does happen this way
  9. A few weeks ago I stumbled into a biker party (this is not a joke). The house was beautiful and the back deck had ducatis stacked up like cords of wood. Present were the Ducati 860 GT up to some 600 and 900SS and some newer stuff. In the back yard, trail bikes zipped around till dark. A Suzuki RGv 250 sat in pieces with a bucket under it to catch the radiator fluid. It was really nice to be able to stroll between the models and just look at the differences. In particular I looked at the brakes and the fuel metering. We have come a long way in motorcycling since 1975. The C172 I flew last week ... Not so much. A few days later I climbed on my Honda with its sequential injection, hit the starter and everything just worked. Even at -5C after a weekend in the shed. Its older sibling and shed mate would have struggled to get out of bed. Nostalgia is the art of picking up a bit of the past, polishing the sh1t out of it and pretending it's worth more now than it was when it was new

  11. I saw a Hipps J3 kitten with a trailer for sale at $15k two weeks ago. Can't remember exactly where but not near me. It was flown weekly and looked like great fun. I wondered for a minute if I could just get it to follow me home but I have nowhere to store it and nowhere to fly it
  12. I wonder, are representatives from d3thStar reading this thread? If they are ... Customer Guarantee | Jetstar So, is not having enough pilots at the same time of the week a commercial reason or not? What about cancellation rates now, since 2010? Australia's worst airlines and airports for cancellations | finder.com.au (for those who TL/DR;) From July 2010 to June 2017 Jetstar is the 2nd worst overall behind QANTAS for cancellations and Sydney is the 5th worst airport Also from Customer Guarantee | Jetstar In summary, you could pay more for the same trip on QANTAS and conceivably get less service (or free entry to the lounge) and still end up on a d3thStar flight because the QANTAS one got cancelled too.
  13. Is this a pilot shortage at work? Is There a Pilot Shortage?
  14. Some of those offers to give up a seat are in 4 digits by the end
  15. I will be looking at RPT cancellations very closely till the end of this year after this thread as I have some multi-leg trips coming up and getting stuck half way would make it easier to just go home. I don't have the option to fly JQ from where I am but I could fly Tiger Scare Ways on some legs. (Apologies to all the good and safe Tiger pilots its not you its everything else about Tiger) Not. Going. To happen. Happily this narrows it down to QANTAS or catching a ferry. Whoever said "Don't fly near or at the same time as Ian" is probably on the money. To that end I will be flying on Wednesdays around lunch time
  16. I am not providing positive feedback or otherwise on the flight training facilities noted in earlier posts of this thread. There are many historical threads on this topic. Have a browse, have a read. Some of the information is quite old and could be out of date but it will be interesting for someone new to the geographic area
  17. Any BS comparisons between US and AU carriers or BS pushes for single pilot operations are just that - BS. AU legislation operates in isolation to US legislation and Australia does not have any US carriers operating domestically. It takes several years to go from zero to the right seat of a single aisle jet so if a carrier is going to die from a lack of (low wage young naive unmarried starry eyed) pilots, the dice have probably already been rolled. Paying sign on bonuses to get REX captains into VA or JQ operations is a symptom not s soluiton. When VA offer head hunting bonuses to anyone who can get a Qantas Link pilot to make the switch to VA ... and the Qantas Link pilots still aren't making the switch (this is rumor not a verifiable fact) you know its not all about money
  18. I was just about to post the same link. "Dear Jet-Starfish passengers we regret to advise you the 17:10 scheduled flight to WoopWoop has been cancelled. Crew scheduling couldn't find anyone not already flying, not fatigued and not wealthy enough that they couldn't refuse ... to pilot your scheduled service". So much easier to not blame the strategic "thinkers"
  19. The Last Minute Hitch: 13 July 2018 - Australian Flying
  20. I know someone who started at 82. He is still going strong at 86. 20 years of flying to look forward to at 66
  21. Hence the name change to Toowoomba Wellcamp in 2017
  22. I just got back from YSCB a few minutes ago flying vh-cwy. Next flight is planned for 20th July. Between now and then, probably not at all
  23. I agree that the aircraft are a lot quieter than the old 727s and similar. So much quieter that the source of noise at flight idle now appears to be air over the gear, gear doors and flaps. I didn't suggest that the people voting in favour of any curfew were going to listen to reason, just that they had enough say and money to vote the member for the federal electorate of Grayndler out of office should the curfew be lifted.
