    That's in still air. It's a fair bit of runway. Darwin's a long runway. (from memory) Those 707 types Had Dutch Roll issues. Wing sweepback.Nev

    WHY bring Rotor Blades into it.? You are just complicating things. It's NOT a propeller. It's rotary wing. Your Prop should be on the fine Pitch stop till you are doing 1.3 Vs. Nev

    .Google Map Helps if you have never been to a Place. Hypsometric tints on the WAC chats and spot heights also . Rivers and Mountains rarely move The Yass to Dapto Power line is useful. Nev

    The exported article should be Minus the Local GST. OUR GST is on everything . Nev

    I think Euro was 60 AUD today so well covered. Nev

    HIS last line is enough for you to go on. You have Manual pitch adjustment as well? WE don't know How the question was Put. The fine CS setting on the control is NORMAL apparently. That doesn't mean the prop is/stays at fine pitch or the Motor would overspeed as your airspeed increases. C/S means engine revs stay constant (over a certain range of Airspeeds). Nev

    Landing distance required is ONLY 1900 Metres (approx. 1 Nm.) Nev

    You check what's in the Element mainly. Use a Magnet to sort out the steel and Iron particles Wash the others with mineral turps or kero so you can see better.. Like panning for Gold.

    With a New Motor Cut the Filter open at the first Oil change. If metal evident try to work out why. Some new motors can have swarf in them from inadequate cleaning before assembly. IF I found that I'd be dropping the sump and check all bearings and oil pump intake screen and let whoever supplied it Know and ask what they want done. You don't want to be caught far from Home and at the Mercy of the Local Mechanic.. Nev

    Flu after the war, killed more People than WW1 did. Russia had a large number of deaths from Covid. In a world where starvation is common, some die from overeating ..Nev

    Think I'd rather a circular rotating cutter. Those single tipped things are pretty touchy how they are sharpened.. Nev

    HE makes it look easy. Nev

    Cut it when OFF the engine so no metal can get anywhere near where the filter sits. You can easily make a dummy holder, There's only 2 thread sizes. One NF One Metric. You can check them on the web. Nev

    More complex than that. Nev

    The centrifugal turning moment tries to force the Blades to fine Pitch when the prop is turning. Nev

    That's the Queue I usually end up on. Hey what you chokin that pick for Man? Nev

    Buyers dictate the price you will get for it. Supply and demand. My eldest always says. Do you WANT to sell it or NOT? Nev

    A "thingamajig will straighten things out. As you get older it becomes a Whatsitcalled. Nev

    Don't confuse Limit stops with Pitch control selection positions. I have difficulty determining what is actually being referred to. CS is Not the SAME as in flight Manually adjusted Pitch which stays at the Position you set it to.. The Fine Pitch Limit stop (in the Prop Hub) is set so that the engine does not have to Be revved too high for you to be comfortably above the Planes stall speed IF the Prop fails to full fine . Nev

    The First production Jabs had KFM motors in them which ceased production and Rod Stiff had to make his own Motors as he didn't ever want to have to depend on other engine manufacturers again. Nev

    Same fuselage cross section as the 3 engined B727. The B 727- 200 version was a lot Longer and carried More Pax a bit faster. Nev
