    Uh ... perhaps "better late, than never" ... ? With the upgrade of facilities here at the Canard Zone, I am motivated toward some upgrades of my own. First, the URL for existing Canard Flight Models for X-Plane (v9 and v10): http://vigilanceaero.com/X-Plane/Flight_Models/Flight_Models.html And, also to mention that I will be working to bring the flight models up to X-Plane version 11 standards, and ultimately to 3D cockpits and VR controls.

    This fellow in Alabama has two Varieze projects for sale $3500 and $5500, as well a a hangar full of canard airplanes he is working on. Here is the link or search FB for Tony Warnock https://www.facebook.com/groups/25741482604/

    I have purchased N40LC, originally built by Lynn Coltharp from Oklahoma. Lynn finished the VE in 1980 and put 569 hours on it over the next 29 years. He flew it out of his airpark home with a 2500' runway. He sold it in November of 2018, and it was resold again earlier in this year (2019). The last owner repainted it and added a nice interior. He decided he would not be able to finish his PPL anytime soon and did not want the VE to sit idle for several years. I started looking for a VE/LE in August and came across N40LC on Barnstormers. I inspected it in October. Everything seemed tight and clean, and the O-200 ran smooth. I bought it and picked it up (by trailer) two weekends ago. Lynn, the original builder, (now 79 yrs old) was the last to fly it and I had a lengthy discussion with him last month, going over his build process and experiences with N40LC. I was able to get all of his build logs, pictures, receipts, and documentation. It appears to have been meticulously built and well maintained. It was well kept during its years of non-flying. It needs some updating and small changes that I have started to work on. I will provide updates along the way as I progress. Here are some of the tasks I will be doing: - Re-balance all control surfaces - Change springs on elev. trim system and rudders - Add a starter - Add a an oil filter adapter (maybe) - Replace most of the wiring - Remove Garmin 250XL - New comm radio - ADS-B out (uAvionix) - New tires/tubes - Swap out pushrod nose gear with wormgear - New canopy seals - New ELT - Rewrap exhaust - New W&B I attached a picture of it when it was new in 1980, and a few recent pictures of it after I acquired it. I had two of my daughters help put the wings back on this past weekend. Note that it has the wing cuffs, not the vortilons, which was the initial suggested wing improvement from the CP's. I appreciate all of the knowledge on this site and the help I have received so far. I am looking forward to being a VariEze owner!

    The landing brake repair made it all nice and smooth on the bottom. I flew in the Cozy with an old friend who has bought an EZ and wanted some time. Looking in my log books, I had flown him in 1999 before he became a pilot. I think he has about 150 hours in Cessnas now. He did pretty well. After a bunch of landings the only thing I was concerned about was the "falling leaf": get slow approaching the overrun, rounding-out early and high, reluctant to let the airplane land. That's tough on my landing gear. When the canard is maxed out (about 63-65 KIAS in my airplane), there is nothing left to arrest a sink rate, hence the name "falling leaf". I like it much better when a pilot maintains final approach speed (75 for me) until the landing is assured but continues his descent to the numbers. The final approach speed will decrease a little but there will be adequate speed left to break the descent and round-out just above the runway surface. I would rather have a guy do an incomplete roundout and land a bit hard than drop it in from a high round-out and try to catch it before it prangs. In my airplane, he had to look all the way across the cockpit to see the speed but still . . . Fortunuately it was an almost calm day. We talked about flying patterns in a crosswind. If a base turn takes 25 seconds and you have 20 knots of crosswind, the wind will move the airplane 843 feet downwind during the base turn (1.68 fps * 25 * 20 = 843) so it is important to start the base turn aiming for an imaginary runway 843 feet upwind. As the base turn continues, you bring the imaginary runway closer to the actual runway. If you don't think of that, you'll have an angling final or overshot final and you can't figure out why. It is the same for 20 knots of headwind: you would begin your base flying to an imaginary aimpoint 843' down the runway (upwind). This is particularly important in engine-out landings where failing to take the winds into account is one of the many errors that will cause you to land short or long. For me, a Cozy pilot is proficient when he can regularly reduce the power to idle on downwind and land on the numbers or slightly beyond without touching the power again.

    Yeah, it looks nice ... however: They asked me to review this package, and I didn't even reply with a critique after flying it. The pilot view-angle is wrong, the flight dynamics/handling are wrong, and the thing is WAY TOO DEMANDING of the PC hardware. The designers have made a nice gaming model ... not a useful tool for real life pilots. So I am working on that problem: greatly improved Canard Flight Models for the X-Plane flight simulator program. And "greatly improved" here means the move to 3D/VR. There are compelling reasons to Train using VR immersion. I will be posting a series of articles here regarding this. I'll include a paper written by another pilot on the subject. I am finally making some progress at learning to use Blender and AC3D, Lua and SASL which are required for converting my canard flight models to 3D cockpits and VR control manipulators. These flight models for VariEze, Long-EZ and Cozy MKIV will be Optimized for Real Life pilots and affordable PC hardware. The goals are X-Plane aircraft for Transition Training, Proficiency, Airport Familiarization and Homebuilt First-Flight Preparation. The benefit from X-Plane that my wife and I had when we each first Soloed in our VariEze is inarguable. I have recently realized that First-flight potential problems is an area that might be of great usefulness. This is where I will explain simple settings changes in Planemaker that pilots can make themselves to create problems such as Lateral Control Imbalance, Yaw Imbalance, CG Too-far-aft situation, Gear Retract Failure, Landing Brake Failure, Avionics failure and others. Training for these potential situations in a newly-built airplane would be priceless. After updating the legacy flight models I have offered for many years, I will make an effort to include other homebuilt types as well. These might include Velocity, Quickie, Defiant, etc.

    Can't forget this one! https://www.youtube.com/watch?v=dU-zw5k2I-I

    Below is a conversation copied from a canard FB page. It is clear that 2/3rds of the respondents do not know what they are talking about or never heard of the Varieze wing-attach corrosion problem. Out of a dozen replies, Joe Person--an old guy--nails it. Tom Watkins gets close. The rest range from ignorance to bad guesses. No one offers a cogent discussion of the problem or supporting photos. Thank you Mr. Zuckerberg. So the OP says "Thank you" and goes away thinking what?

    Done some brief testing. Seems to be decently representative, though I wouldn't consider the flight-model to be particularly precise; It uses NACA 23 series airfoils, control surfaces are not accurately sized, stuff like that.
