    Thanks. Just what I wanted to know. I have had my GA since the early 1980's. Then I did all my flying FullSAR. Since 2000 all my flying has been via the magenta line. Since 2007 via 430 into autopilot. It has come time to do my biannual flight review. This time, for the first time, I have been asked to do 3 hours of desk office review plus a 2 hour navigation solely on visual. First I find that NDB and VOR has nearly disappeared, I used these heavily before GPS. Now this is going to cost me serious money. So I am looking at a rec licence, I don't do long navigation flights any more and essentially only on my own or with a friend. So the question is if I have to do it for GA why not abandon GA for Recreational flying? I assume that I would still have to do a navigation exercise, maybe not so long, and the desk exam pass, is this so? If my GA licence has not got a BFR what restrictions would I have on a recreational licence? What medical would I need in the future? I now have a class 2, it is very expensive with a yearly stress test and heart ultrasound. Needed for age alone reasons.

    Is navigation training for RAA allowed with GPS?

    Unfortunately Cowra takes a long time for me to get there. But I like your idea.

    For me it is more about keeping costs down by trailering the aircraft. I paid a small fortune for hangerage when I had my GA aircraft. Being timber and 'fabric' the craft cannot be stored in the open. But i think that all that i would have to add would be cable quick releases. Geoff

    I have noticed that the aircraft with folding/removable wings seem to be metal aircraft. Is there a problem with removing and retightening timber bolts? What if the Corby was trailered by removing and re torquing the attachment and inter spar coupling bolts? Besides taking a long time would this deteriorate the timber from stress cycling (assuming that the bolts are not used in shear only capacity?
  6. Geoff_H
    I like it. Any details on the way it was converted?
  7. Geoff_H
    It appears that there maybe a 2 piece spar option with a joining plate in the middle. I was wondering if anyone had worked out a way to separate it or make some other arrangements for quickly changing the wings. If I bought one I know that I would prefer to trailer it. Geoff

    Has anyone made a trailable Corby Starlet? Folding wings maybe, or even removable wings with a reasonably quick reassembly.

    So true. Can't tell you how I know. Happens to a friend of mine.

    Once mild cases of autism were called NSD (non specific diagnosis) now they are called autism and often ADHD. People that were highly functional and have low interpersonal abilities were just regarded as different now they have something that needs examination and limitations. My daughter is like that, has a phd in a medical field now writes AI software for a medical company. She would be limited in flying, she uses ADHD drugs. Her worst feature is the drop kick she married and her subsequent boy friends. I will not get diagnosed, the diagnosis may be limiting after over 40 years of flying. It is interesting that CASA now asks the industry, rather than their own investigations, if the result of a rule change turns out to be wrong they can claim reduced responsibility.

    They are the GOTO at the moment. It is difficult to get stock and prices from them. In that respect aircraft spruce are great. Aircraft metals have not responded to emails.

    I did think of substituting 6061T6 to 2024T3, but after comparing their respective properties I decided against doing it. 6061T6 is far inferior
  13. Geoff_H
    Yes I expect to buy 6061T6 angle from them. Unfortunately they do not stock any 2025T3
  14. Geoff_H
  15. Geoff_H
    Sure. I am having trouble finding Australian suppliers. But I will buy from Aus where ever possible. Aircraft Spruce seemed like a godsend, not so sure now.

    I looked for a 1/4" bolt that I selected at random. No stock. Rivet random selections were both in stock. Shipping appeared normal for Australia. The sheet 2024 and angle 6061 shipping costs worried me a little, no estimate of cost just billing on shipping, an open cheque more or less.
  17. Geoff_H
    I wonder what stock they have? No .o4o 2024 T3 nor 1.5 x 1.5 inch 3/16 6061 T6 angle.
  18. Geoff_H
    How much are you wanting for it? Any pictures?

    My vehicle actually has laser lights. They are reported to have an effective range of 600metres. They are inhibited from operating where there are street lights and the car is exceeding 60km/hr. They have a pretty heavy heat sink on them so the speed limitation might be for cooling

    Both the laser and led headlights in my car are dot controlled. If there is a car in front or coming head on the dots in that area are turned off by their computers. One time when the laser lights came on there was a car in front of me, it only lit up the left side of the road a few hundred metres in front of the car in front of me. I don't know what that driver thought seeing the side of thr6road lit up

    After a websearch, always a little dodgy, I am sure that for thin thicknesses laser welding could be great for the homebuilder. Less distortion continual good penetrative and ease of use by amateur. I did a google purchase search on laser welders. 90% for sale are tig or stick etc welders. The price of welders from that laser search ranged from around $1000, very affordable. But on closer inspection none of these were actually laser, usually tig (already have tig set up so not at all interested). Then I found that the cheapest laser was $10,000. Just a lot outside my budget for new tools. $25,000 for a reasonably capable machine ( and I really do not know what makes a machine more or even less capable). To buy one I would have to be building a steel tube large aircraft to even start to think about one. Maybe one day they will get cheap. My car has laser headlights. Supposed to be able to light up to around 600metres ahead. The car manufacturer does not offer them any more. They were a $2k extra, I guess that they were not considered worth buying and hence not in demand.

    It apparently can make professional welder out of a dog dollop welder like me. It appears that you melt the filler the the filler transfers heat to the metals to be joined. Fast weld less heat into metals so less buckling. Expenditure for equipment that is needed to be purchased is vague, I don't know all that is involved.
  23. Geoff_H
    Anyone got any experience with laser welding for aircraft?
  24. Geoff_H
    Yes. Gliders have a very short relative tail to aileron distance so much more rudder is needed to counteract adverse aileron yaw. It's as you said a matter of rudder force times distance of the rudder to the centre of gravity creating a moment on the aircraft.

    I believe that casa have committees that look into your fitness to fly. Takes a while to assemble a lot of people. Committees are great no single person can be responsible! Consultants are often used as a means of deflecting blame,,
