    The Hi wing Cessnas with retracts have a very unusual and complex action. They have more drag with a part retraction than leaving the gear down. Having said that there is usually an emergency extension process.. Nev

    As far as the Factory is concerned the total Market is the main concern. Aero engines will only EVER be a relatively LOW volume thing. That's the problem with ALL of them. and why so many do not survive. I wish them ALL good luck and it's good for us that any of them attempt it.. Nev

    BMW don't have excessive cylinder Offset. . The effect I described is well known with engine designers. 3 cyls and narrow V 6's are not uncommon. Many fours in line have curious firing sequences for the same reason and there's plenty of 5 cylinder engines. Many flat four designs have crankshaft breakages . Some People who raced the aircooled VW's changed the crank at 6 hours. Nev

    I am reliable informed YES but it was NEVER put in production because of the vibration.. Nev

    It's all pretty risky. Leak proof well secured and vented externally should be the go. Nev

    Most are not aware of the advantages of a V twin over a boxer twin. The Jabiru twin was not a success because of the exaggerated offset of the opposing cylinders that results from having a mainbearing for each throw of the crankshaft. Nev

    You need the actual Aircraft basic wt and Index to start from. I made a graphical chart for the Citabria. It had a lot of room behind the rear seat and had to make sure the weight didn't end up too far back. . Nev

    That IS the difference. It cost Jabiru a fortune to certify some of it's stuff.. CASA would probably accept an FAA certification. or maybe BCAR . You couldn't be sure . There used to be stated ways of getting an applied TBO.. If there was a spate of failures it would be reduced. Some of these TBO's would be in the realm of an optimist wish. I'm not necessarily targeting this motor in my statement. The Rotax 9xx series need good quality control with fits and materials due to some of it's design features.. Reverse engineering might just drop SOME critical aspect and it doesn't take much.. it's NOT easy to make a good aero motor. Porsche didn't succeed. Nev

    I have seen a few pilots who on a new type have reverted to the Previous one. on some aspect like rotation rate and initial pitch angle That's obviously not a good trait. It is also likely to happen when the flight is back of the clock and you've not rested. Flare height on a different type may be vastly different as say a DC9 V/s an A-300 which is about 5 times as high and has a radio altimeter to help/confirm. When you first go on one, the Landing is more like Low Flypast. My first Thruster in 86 was after a full day of B727 legs the day before. It was at Mangalore at an Airshow and only 500' max in those days. I did the circuit OK . Just another aeroplane. Nev .

    There's a lot of room between a flying car and my bum and it will probably stay that way. Nev

    I have seen ex Big stuff people who want to have lots of instruments and who certainly miss having good anti icing systems, but often their background experience is still there. Don't make the mistake of putting people in"Boxes". Many Heavy aluminium drivers would never fly say a drifter or thruster and have NO DESIRE to do so but PLENTY have flown them well and even things more basic like MX's. More experience is rarely a burden. The more types you fly the more adaptable you become. It's pretty easy for a good instructor to tell if a certain pilot is all BS ,hot air and overconfidence.. An aeroplane is an aeroplane etc. Nev

    Moneybox ,space is for spacey. A further note, all masses act through their individual CofG's. Nev
  13. facthunter
    Yes it's BEST not to assume. but any mass which is situated IN the Range of allowable CofG won't take it Out of the range regardless. Wing mounted tanks often fall into this category. It's wise to KNOW where your actual C of G is. It can affect your performance. Slightly tail heavy is more efficient. TOO tail heavy is the most dangerous. Nev

    A V twin has better torsional momentum charactistics. There is a BEST angle of the V.. Nev

    Your basic lack of how W&B works is showing, space. It's REQUIRED to remain within the range of the Stated limits. Otherwise you are flying an unairworthy plane. Naturally the further things are from the CoG the more the effect. Nev
  16. facthunter
    Good plastic strapped down and vented would be fine. A lot a vehicle tanks are plastic. The plane must be in W&B limits when full and empty. Nev

    IT will sell ONLY IF it is substantially cheaper than the one it copies.. That's the Chinese way. AS far as a squeaky clean workshop and neat looking young people even the Royal Enfield factory looks like that. I'm NOT saying the product is junk but it's reptation has to be established. Nev
  18. facthunter
    The Price has to reflect the Uncertainty, Rotax IS very expensive. Experience in the field matters. Also the quality of the installation obviously matters. THAT may vary to quite a large degree. Nev
  19. facthunter
    They are NOT a Certified engine. I wonder how many parts interchange with the Rotax equivalent? How will Rotax handle the competition? Their motors and parts are Very expensive.. No Aero Motor is really ever going to be made in the numbers that Auto S are. Nev

    Probably FAR easier to assess the condition of an EV and be able to warrantee it once you put your mind to it, than something conventional or a Hybrid. Nev
  21. facthunter
    Spoils a lot of theories when you get FACTS into the equation. The maintenance is almost non existent also. Nev

    They (CASA) have been all over the Place with ADSB . Its expensive. Gliders use Flarm. TCAS is interactive with other traffic, Vertical separation is certain to be effective if you Baro procedures are observed,. Good radio as well. and look outside the cockpit. and use the passenger as well. . Nev

    Make it Happen, space. Life is short. Nev
  24. facthunter
    Use it to remove sludge etc from the innards of old engines. or to remove grease and wax prior to painting. Nev

    Don't think I had that on my Garmin. Anyhow unless you are over large stretches of water where one wave looks very much like any other, it seems like" by reference to features" gives more reality to the process and a sense of where you are. More awareness of what you are flying over. We are all by nature LAZY and tend to cut some corners as we find out how or presume it will be Right." I'm so experienced I don't need to bother with THAT stuff, any more" . Nev
