  1. Sailing and flying overlap. Surface winds exist are not predictable. Planes do not run on rails. Like a sailboat they respond to wind they encounter.. Local knowledge is the key for many situations. Anabatic and katabatic winds, standing waves, mechanical turbulence Dust devils etc as examples Nev.

    Not to forget Rotors on the lee side of hills Nev probably wouldn't worry sail boats but aircraft close to stall speed and low to the ground something to be wary of.

  2. And of course in Australia we have heaps of VOCs (volatile organic compounds) from napalm, er gum trees. They ain't called the Blue Mountains for nothing. I suspect a few two strokes are negligible. We are governed by idiots as will become obvious when the lights go out.

    I think the term for some of it is polycyclic aromatics

     

     

  3. Anyone fitting them and not noticing shouldn't be allowed near an aircraft engine. "Boss, these bushes are too loose. They press in too easy".. Nev

    Being an aircraft engine as in all interference fits od of bush and ID of rod should have been checked and known

  4. You could just let the tail come up as the speed increases and take off in a tail low position. You get airborne at an airspeed slower than if the tail is raised , to the more level position and positively rotated for lift off. You then have more control of where the plane leaves the ground. Better in a crosswind. A fair amount of rudder trim is preset. On a sealed runway you can judge by the edges it you are tracking OK but it you need to see where you are going you need the tail up sooner. You can't see much in a C-180 either, let alone a long nosed piston engined fighter. The undercarriage is very narrow making weight transfer due engine torque or crosswind more likely. A geared engine may possibly cancel out most of the gyroscopic precession as rotating masses are in opposite directions. "P" factor is not happening when the pitch is aligned with the relative airflow. Weight and power together give an index of acceleration. Power weight ratio not just power alone. Nev

    I think your right Nev the strip was u/s to this type of aircraft maybe the old heel test on the turf before flight and kick the tires before lighting the fires or spitfires in this case..

  5. Thanks for the link Bex. It seems pretty clear from this brief account that the Ford boys definitely did the wrong thing and then tried to cover it up. Management can be aggressively dangerous to workers and (of course) labor sometimes get out of control. Nothing to see here...move on! Hehehehe. No offense meant Don:wave:

    Nothing helps like taking the workers outback for a weekly whipping until moral improves.

  6. I am not talking about the innovation, I am referring to the 120 million investment and the ongoing costs, and what returns are mathematically possible.Henry built a cheap simple car that everyone could afford, and invented the production techniques to make it possible - the very area where Icon are struggling. There is literally no comparison between the 2.

    These days it costs 120 mill to build a car park or pay a bunch of consultants to tell a local council what it already knows and the janitors cat has more wisdom. Give them a go

  7. Many have been predicting that for a long time. The math has never been there for the 100 million plus invested.Get lots of investment, pay yourself whopping salaries, sell your shares at peak, then find ways out so you walk away rich. MBA 101.

    Probably was said about a lot of innovators just maybe the world will end up with a great little aircraft remember a bloke called Henry Ford.

     

     

  8. So recent incidents have made me revisit this thread.Without doubt for me the two most disappointing things to come out of this incident are as follows.

    Julie has only been up with me a couple of times since the incident and to be honest I am certain that it was only to show some trust in me she has however lost any passion that she may have had for flying which was I will admit minimal to begin with.

     

    RAA's response was dismal as was Foxbats. I would simply never bother submitting another incident report.

     

    As callous as it may sound, any interest in this incident died with Maj.

     

    So disappointing. I have as a result become a critic of RAA and their reporting procedure.

    Sorry to hear that Geoff it seems RAA is more concerned with paperwork than groundwork.

  9. Rotax 912 ULS powered Savannah MXP 740 owner here, British but retired in France, just logged in after googling the thread about cracks in the nose wheel bracket. Great to find such a lively and well informed forum. Came across the thread after stupidly bending my nose wheel leg and smashing my Duc 3-blade prop. Now in the process of getting the leg straightened (only a slight bend) and fitting a new 3-blade Ukrainian scimitar prop. Hope to be logging in regularly from now on and especially following news and updates on the good ole Savannah.

    Welcome rollerball
