    I'm very careful around aircraft and not likely to change at this stage and I've not scratched a Plane or injured a passenger. The situation where you can't say a word about Rotax that isn't praise is JUST not Logical. You're Paying a considerable price and expect it to be good. All things CAN fail. .I Pick on all Motors Non are perfect, Even the Merlin never had a TBO above 650 Hours. and that's got RR in front of it. Nev

    It stands to reason that a Motor with Less hours will be MORE reliable. The cost is for insurance covering the added risks of running engines over the normal TBO. You don't run Aero engines till they start to lose performance. Planes are certified on the assumption the engine makes pretty much the Power it did when new. It's a well Known fact that the older engines deteriorate faster than Better condition Newer ones do due Mainly to less engine contamination by blowby gasses etc Nev.

    They would have to be aware of the shortcomings. They are NOT idiots but at the end of the day it's about $$$s and a relatively Low rate of production As compared to the MASS Production unit cost. ANY experienced Race engine tuner Knows the fundamentals of all this. Carburettors should not be on the top of an aeroengine. Fuel lines too are in a bad Place and heat rises after an engine is shut down. it seems you only read what suites your case which is Basically it's Rotax so don't you dare criticise anything about it which is illogical. I evaluate ALL engines I have to deal with and Plenty of so called good (and expensive) ones have Basic obvious weaknesses that let them down. Nev

    That plane's wings to start with But No plane has an aerobridge Hooked up and some are Positioned wrong. Nev

    This Obviously WORKS is NOT the answer. That's confirmed by the Bolt instead of a spring and extra inspections which Indicates excess pressure in the Bowl which has predictable consequences. It's NOT negativity to investigate and comment on such things no Matter What brand of Jigger it is ON. That particular Carburettor is a Pretty cheap and Nasty thing to have on a modern (and expensive) engine in an aeroplane. It's way out of date. There's infinitely Better stull on good ride on Lawnmowers with one throat to each individual cylinder. nev

    I'd say the whole thing is faked. There's a Lot of things that don't make sense with that Picture. Nev

    If you believe that your experience is very Limited. Most engines give Little or NO warning of a failure. Lack of proper servicing causes Failures and not Treating inhibiting engines that SIT unused or an overheat or overspeed that may have happened quite a time earlier. An AME that Knows particular Motors Quirks can keep them reliable. That may Mean looking at things Before any symptoms show based on vast operational Knowledge or experience with the Engines in question.. An Ansett DC3 crew experienced an engine failure and came unstuck when a rough running engine experienced over a few days was shut down but the Failure was in the Other engine that wasn't running rough. It's dead foot dead engine But they Jumped the gun by ASSUMING and anticipating . Nev

    Rubbish Mate. Face FACTS. Facts can't hurt you. Blind trust can. It's NOT a new principle. and O/T covered it thoroughly. I don't see that as unsubstantiated. Quite the Opposite. Nev

    With grapes you HAVE to cover them with nets once the Grapes start to ripen. Gas guns etc just tell them "Dinner's over here". Nev

    VERY well explained. Simply put, the carburetter is not designed for it and can't really be. Injection would be fine. Direct preferably That would stop damaging backfires, that can happen on start up Nev

    Nothing will work for Long . The birds get used to it Nev
  12. facthunter
    It's not often done and is generally considered not to be the way to go with float carburetters.. Nev
  13. facthunter
    Limiting the elevator authority is like having your hands tied in case you do something wrong. The Nut on the end of the stick is the Problem. If the plane is nose heavy you can run out of Back stick in the flare..Nev
  14. facthunter
    Boost THROUGH a carburetter is not a great idea. Full stop. Nev

    You have to decide whether it will perform or it won't There's ways of determining that. Like what altitude will it easily achieve in those conditions. Some Planes wouldn't make 3,000 feet so I would not even try, The Lsa 55 Jab is a bit of a rocket with the small Motor also but just Off the cuff, I would think the 230 is Better. How readily it gets airborne is another confirmation of capability. The 4 seat Version struggles in hot conditions, understandably. Nev

    I've flown a 230 at Ballarat as the owner was anxious to complete the training at 42 degrees ambient. It performed well enough but for the Occupants it is just Awful. You can't function in those conditions. It went back in the Hangar. fairly quickly decided by Me. . I recall some other small Plane was flying too. There was no issue with the engine temps if you climb at a faster speed. Ballarat is well above sea level Enough to affect performance significantly, Nev

    SS in SS is dicey anytime it tends to gall and weld,. In other circumstances watch for dissimilar Metals with salts etc (electrolysis). Keep dry or seal from moisture. Nev

    Is that Posted in the correct topic? Nev

    Anyhow its Foxes 3, Roosters NIL.' Nev
  20. facthunter
    That's their Job. It's a fowl task. They get taken for a ride often. The foxes silence the Ones my Neighbour keeps purchasing. Thank Dog,. Nev

    How much elevator you Need to flare depends on the C of G, and with some 3 Pointers the Plane is stalled Purposely. Stick stall Position is only for One configuration at a time. Nev
  22. facthunter
    Moor or lessabin. I goi inside when it's above 30 C. Mad dogs and Englishmen go out in the Mid day Sun. I hate Heat.. Ideal temp is 24. Nice day today. The Ulysses Boys were lined up ready to go at 10 00 as I went to the Men's Shed. Nev
  23. facthunter
    Not referring to this specific Incident. Just a general comment and density altitude must be allowed for Always. Best climb performance once airborne will be with flaps up. (Rate of climb). Nev
  24. facthunter
    Easily fixed by raising the climb speed slightly BEFORE the engine temps get too high.. Nev
  25. facthunter
    Not in an aeroplane. No one has ever aimed for that. 2.000 is about where that is. Remember race cars are stripped and checked between race days. Jet engines can go to 10.000 but have Hot end checks regularly and visual checks on every turnaround. and debris checked in filters. Anything there and she's pulled and stripped. That's why aviation is safe. Nev
