The previous link is to a description of the longest time flight. Held by a Cessna 172. Well over 60 days. I could not hold for that long LOL. It was in 1958.

I bought some very light and fine close weave. You don't roll it you just crumple itto a ball. So fine that it doesn't stay crumpled. It will cover very tight edges. You can have the small quantity that I have if you wish.

They don't let you out of hospital until you can achieve that level of emptying. They measure residual urine using ultrasound scans.

After years of finding the nearest strip for a pee, I no longer have a problem. I got a TURPS operation. I can easily go down to 30 ml in my bladder before the flight. Hanging on for 4 hours no problem.

I have 2 single cylinder engines. I need one engine. A single cylinder engine has put of balance forces in the xy plane.i the engines were contra rotating and synchronised the vibration would only be in the Y plane.

95.55 amongst other things states: (b) that has a single engine and a single propeller; If an engine was made from two small engines bolted together with each driving through belts or gears to an output shaft that is attached to a propeller would that be a regarded as a single engine? One starter motor and one set of controls.

Yes. The picture is of the one for sale. I am trying to find what happened to the other one. The one in the picture was damaged. The other one flew until 2011, why did it stop flying?

Anyone know what happened to one of the two KOLIBRI AK4 imported into Aus around 1997? One was damaged before being registered (the one in the picture) but the other was registered on 7/7/1997 as 24-4530 and deregisteted on 7/1/2011. Does anyone know why it was deregisteted?

Hi Nev, I expect that your artery is the same one that I have. Found in 30% of the population, always comes from the aorta and goes to the heart in addition to the other 2 all people have. It is never found in babies. Nature have you a premature bypass operation. I am no cardiologist but I expect that you have a good cardio system. 😊

The Did one of my usual aerobics classes this morning. Max heart rate according to Samsung watch was 188 bpm. I have not dropped dead yet, if I do I will keep you all informed. Lol Actually it is not good, it happens before my body heats up. I pushed too hard with cold arteries/ veins as soon as they heated and expanded the maximum was 165 bpm. Much more reasonable. I have had an angegram ( x-ray of heart with die injected) it showed minimum artery blockage. It also showed that I have 3 arteries going to the heart, normally there are 2. Nature have me a bypass operation lol.

I continue with the Class 2 medical because the Class 2 Basic cost me more than the class 2. I also had ideas of doing some aerobatics. I did the Basic some years ago and the eye test cost made it too expensive. Now I have to do a stress test maybe the basic is an option. Does anyone know if I need a stress test for a Basic?

In the late 1990's CASA published an article saying that there were five medical issues that could loose you your medical. If I remember rightly heart, diabetes and three others. In that time your DAME was instructed to ask how much exercise you did at the time of your examination. I replied that I walked to the station, around a kilometre each way, he said he would give me a yes on that. At the time I thought that he was being too generous. However despite many go it alone exercise attempts I started doing aerobics in 1998. It is a passion that I do this day. My resting heart rate hovers around 50. My biological age is 20years younger than my physical age. I would recommend it to anyone. I have to thank CASA for my fitness and enjoyment of life.

I expect to live until 99years of age, then expect that I will be shot dead by a jealous husband. Said first by some American celebrity

116% was coasting, I was still walking and they terminated the test saying "that's enough we don't need anymore'. My heart rate will go to 180bpm. This morning at the gym I got to 184bpm no pain at all. I have had a test that injected x-ray dye into the heart area and had only small blockages, much less than 40%. It is with these results I wonder why I have to pay for a yearly stress test, my age? Certainly not my fitness. By the way I have to suit comprehensive blood tests every year. I take these anyway every year and they have always been in the centre of the correct range for my age. It is pretty hard to keep anything from my DAME, she is also my GP.

I just recieved my 2 year Class 2 medical. Only eye correction required, another story altogether. But they require that I do a yearly heart stress and ultrasound etc. I do a two year test anyway, and the latest test was that I could get to 116%heart rate. I am 75. Has anyone over 75 also got this requirement?

Well my experiences with instrument control systems says that it is. 45 years of instrument control system work I was wrong it appears. When both ends of the shield are earthed a ground loop current can exist in the shield, this current can induce currents in the conductor it is shielding. Earth only one end of the shield and no current from earth loops appears. But I submit to your superior knowledge.

Not quite sure of exactly what your system looks like but could be owing to am earth loop in the shield. A cable shield MUST be only earthed at one end or the conductor inside can get all sorts of funny voltages appearing. When RS 232/485 control systems were introduced I was a contractor and earned a tidy sum fault finding new installations. Most time it was because the installer had earthed both ends. A side cutter and disconnect one earth and bingo the control system fired up and worked.

I have flown through there many times when I was living in Kalgoorlie. There are no places to land between Southern Cross and Kal. I had a door come open half way between the two and had to fly with a wind fury in the cabin for 20 minutes before I could land at Southern Cross. Flying through there at night means that your engine has your life in its hands.

Over the years I have noticed so many marriage problems for aircraft builders. In the 1970's a friend was building a VP1. His wife left him for another woman. I have stopped building my own design because of the extreme hassles I was getting. Why do our partners object so strongly? Sorry if this is a little off subject. I hope things work out well for you PP. I am behind you all the way. Your craft will be great, you are putting a great effort into it.

I am becoming very interested in building a D1. It has a retractable steerable monowheel with a tail wheel and small wing wheels. The way that I read this thos aircraft cannot be registered in RAA and the pilot needs a tail wheel endorsement. Am I correct in this?

90% of the axial load of a bolt is taken in the first one and a half threads. A bolt with a lower modulus of elasticity make load 90% in a slightly larger number of threads. So lock bolt material would not worry me so much. But the galvanic action of dissimilar metals would worry me.

Richmond hangars were sometimes available at Richmond but very difficult to be a pilot other than the airforce personnel . You will possibly have to let them rent your aircraft. I don't think that they use RA so that maybe difficult. I walked away from leasing the Mooney I owned as their lease requirements were unacceptable to me.

I have used two nuts locked on a thread in the lathe and carbide tools to cut down nuts. This system keeps the tool away from the jaws and an expensive collission. I have also made nuts using hex bar in the lathe. Beware of cheap Chinese dies I have bought some online that don't cut a thread that will connect to a standard bolt. One fastener supplier that sometimes has the odd fastener is Lee Bros of North Parramatta they are an outside chance. But if you find that they have one I will buy it and post it to you.
