    Specialised application. Good design. light engine. Nev

    You lose a lot of heat when it's ducted. Water in pipes and heat exchanger weighs a bit.. The heat Pump gives you heating and cooling at good efficiency. Nev

    Big PASS on that Contraption. Nev

    Have you flown Rotax 912's in cold conditions? To get the temps right you have to do something like block 1/2 the Intake with foam rubber. I've also used electric Carb heat successfully. Your second sentence makes no sense, Glen. That would be a very inefficient Alternator, with those figures.. The Dreamliner is airframe deiced entirely with electricity. Yes the other stuff is free, but not entirely without consequences. Perhaps a small Heat pump could cool the Plane as well on hot days? Nev

    It behaved as if it was flown too slow. (high drag) IF performance is Marginal clean up and accelerate in ground effect. A headwind won't make any difference to stall speed but maybe early give an impression of performance that can't be sustained. Maybe the throttle wasn't fully open? Stranger things have happened. Nev

    You can't be serious. What about the TRIslander tail Mounted engine? How'd you Like to SPIN one of those Babies? Nev

    A pipe shroud will make the Pipe Hotter than normal when no air is flowing through the shroud. You have to use it or vent it. You don't need anything like 1000 watts in a small area if it is sealed reasonably. Taking more heat out of the coolant is likely to cause it to run well below Ideal in freezing conditions. It's only cooling the Heads, not the entire Motor. Nev

    It would only be an undamped slip/skid indicator. In a Barrel roll, it would continue to Point to the floor even when the Plane is Inverted. Nev

    The coolant use would be when the Motor is Probably already tending to be Overcooled in cold ambients. Consider a small electric unit driven from the Planes electrical system? Nev

    It's useless. A pendulum is worth nothing once you are Moving. Nev

    There's a 1.5 FACTOR on that. STRENGTH rating . I would think the Starlifter is no different. Look it up. Nev

    Military TRANSPORT, not dog fighter. SAME figure. Make them too strong, (Heavier) and the Payload and range diminishes. Already Most Planes can't lift a payload more than their Empty weight figure.. The Dreamliner might be an exception

    N0 Civilian transport has an ultimate G above about 3.8 . You have to be careful with all of them in turbulence etc. Nev

    The Later composite ones are high tech. The Allison engine runs at Constant speed. Power is altered by prop Pitch and fuel flow. An overspeeding / Runaway Prop would result in the loss of the AIRCRAFT MOST Likely. The Props are synchronised and ALSO PHASE synchronised so the Blade relationship to each other engine is controlled. Many safety features like Pitch Locks and auto coarsening are an essential Part of the Steel Props I am familiar with The Hamilton standard and Have never seen one fitted and it would have needed extensive Modification to be adapted. Brendan There's Plenty of ways a wing can come off a Fire Bomber. Pulling excess "G" is the Most Likely. Nev

    Look it UP. They have hollow Blade steel Props. Nev
  16. facthunter
    That would explain it. Nev
  17. facthunter
    I thought they would be the same as the Electra and Orion.(Allison Motor) I know it's Fatigue. They are hollow and LARGE with all sorts of overspeed and auto coarsening features and vibration Monitoring. Nev

    It does a Job and gets up Hours.. I think the Caribou is the Noisiest . P&W R-2000's with exhaust augmenters. You can hear them 20miles away .,Nev
  19. facthunter
    The Propellers are Made of welded steel sheet and often get Fatigue cracks in them. A vibration meter usually picks it up. Near the Hub is a "dark sheath of Hard rubber"? that can hide some cracks with only a visual Inspection. Poor Maintenance I would suggest and why fly people in an unpressurised Plane? Nev
  20. facthunter
    Maybe flat spin with fuel venting. Perhaps the Tail separated. It has 4 turbo prop engines( visible) . Nev

    Won't be applicable to U/L's for a while YET. Nev

    NOW you have qualified it. Thanks. Nev

    Timing is everything with weed control. Get them Before they seed. Hot steam will kill them Just after they shoot. Very environmentally Friendly. There's an OLD saying. ONE years Seeding SEVEN years weeding. Plough it up, and NEW seeds will take over unless there's no rain or you don't treat them at the right time, Weed control IS a BIG issue and an exact Science. Herbicides are POISON. Glyphosate is Now in everything including breast milk. Thanks to genetically Modified Glyphosate resistant CROP seeds being used widely all over the world and the crop being saturated with Glyphosate to control any Weeds. Monsanto's Brilliant Idea. Nev

    Not really good advice to put out there, without qualification,. Nev

    Pilot's have a smoother approach. (It is said). I think it's the Uniform. Nev
