    Coronavirus: I posting to this thread because it gets a lot of hits. Chris Martinson has a PhD and post-doc work in neurotoxicology. He has done a daily youtube on the C-virus but this one is particularly good because it discusses the importance of keeping your virus intake (inoculum) as low as possible in order to give your body time to recognize the virus and build antibodies. Apparently, we are all going to be infected eventually but you don't want a huge inoculum of the virus to start with. If you don't want to watch the whole thing jump in at 14+23. Good luck pals--see you on the other side. 🙂

    Saw an article about this chap (video) who is pushing a program to train pilots against synthetic aircraft for the military using a Berkut. Interesting. It seems the synthetic airplane is projected in the Berkut pilot's helmet and they fight it out in the air. I wonder who is "flying" the synthetic airplane? The Air Force is 2000 pilots short and having a hard time training enough people fast enough. I don't know why they just can't use simulators which are fantastic these days. In about 1977 I went through an air combat program run by Vought in Dallas. Vought had set up two spheres with a cockpit in each; the opposite aircraft was projected inside the sphere of the other. They could set us up line abreast or head-on and we would go at it. There was not much else to it except a crude ground projection and the opposing aircraft. You would maneuver for a gun or heat-seeker kill. An instructor could sit in a chair beside your cockpit and reverse the last 10 seconds of a fight and show you where you went wrong. Even that was great training (and fun) for basic close-in air combat.

    Eureka uses a CNC hotwire machine - it's still hotwiring. Steve does not machine the foam. Accurate, but hotwire, nonetheless. I'm at a loss to understand the belief that fabricating ailerons is rocket science - building a set of new ailerons, if required, should take a long weekend - maybe 3 - 4 days, just because there are about 4 serial cure cycles. Two skins, end ribs, and some reinforcing. Use 7/16" steel rod or tubing to put lead weight inside, and ensure good balance. It's just NOT that hard.

    I'm with you Ken. Google searches find none of this stuff on Facebook. And in a few months, to see any older posts, you'll have to scroll and scroll and scroll downward in the FB posts. Don't know why everyone likes FB so much.

    Now that's funny... I see the downloads Jon.

    I see that a chap on FB is trying to diagnose cooling with a wireless manometer (pic 1, $118). He got a differential of 3.86" (pic 2) which is 30% less than the Lycoming-recommended 5.5" for an O-320 so it's no wonder the engine runs hot. The chart (pic 3) looks official but I don't know what it comes from. I would not have used the small piccolo tubes that came with the kit (pic 4). I would have used longer ones (pic 5) and mounted them just above and below the cylinders--seems more accurate that way, and I would have plumbed the manometer to the cold side of the firewall or cold side of the baffles. He says he has only 1" from the top of his cylinders to the cowl. Visualize: air is blowing out of the fins (at what velocity--100 knots?). One inch later it impacts the cowl and has to make a 90° turn. What direction does the air go? Aft, off to the side, towards the engine centerline? Who knows. My guess is that the small space is creating back pressure and not allowing the cylinders to evenly pass air through the fins. Sharp turns, turbulence and nearby surfaces create cooling drag. Here is my gripe with Facebook: Most of the pics below are in the chap's thread but you would never find them with a search and they do not show up unless you click on every "view 8 more replies". It is a dog-ass way to display and archive good information and a shame the canard community is divided among 4-5 FB sites. 😞 tags: cooling manometer pressure differential piccolo tubes

    I use the whiz wheel to torture my wife: “we are at 12,000 feet, 5 deg C, 125 KIAS. Compute our true airspeed.” Always good for a laugh. 🙂

    This is a very stock per plans VariEze with excellent workmanship. I was involved with the initial construction on the Fuselage, Wings & canard. I would go to Ron’s house and do a hot wire cut, foam carving or layup on his VariEze, then he would come to my house and do the same on my VariEze. For the next part, we would switch the order, so no one A/C was a learning curve. Ron was flying Ken Brock Gyrocopters before he built the VariEze, and gyros seem to have been his first love, developing into one of this nation’s leading Gyro instructors, and Gyro kit assemblers. His VariEze is being sold as he has not had the time for it the A/C deserves! This in a good solid well built VariEze that Ron has always kept in a hangar. Best regards John Lambert From Ron: My VariEze N 718 RM has the following history: First flight-- Sept 19, 1982 Last flight--march 12th 2010 Total time engine/ airframe 1,040 hrs Total time on new engine rebuilt 35 hrs New engine installed 2004 $25,000 Ronald Menzie [ronsgyros@gmail.com]VariEze For Sale.pdf 501-766-6456

    Thanks Kent, just restoring a 0290 powered EZ. Have the plans out at my hanger, but plane is at home. Will get them, here could I upload them to so they are available to others?

    Great video, never saw this before. It shows the nose-gear pushrod system that I currently have...
