  1. A recent update to the forum software has given us another way to quote posts when replying: Click and drag your mouse over the text you want to quote to get a "Quote selection" button to appear right near your selection. Click the "Quote selection" button and the selected text will be included in your reply at the place where your cursor was last at. Repeat as necessary. Simple, and works great!
  2. That's a shame, and now a fairly involved repair (replace the entire canard, rerun lines, cables, etc.), but at least you can keep the wheels. The first thing I think when watching folks stress-test their wings is, "ok, now get that stuff off of there now!" You'd still want to rebuild that Quickie as a taildragger, which (being a taildragger) is the source of most of the Q's reputation. In other words, you could say that all taildraggers would behave better on more conventional gear. With the Quickie taildraggers, the effect of braking is much more pronounced than if the wheels were closer to the centerline. In the air the setup is more efficient than a conventional tricycle gear. I think the 3rd airplane I build/own will be a Q1. Looks like great fun with a tiny engine! 😉
  3. The very next email in my Inbox after this post's notification was from EAA about a discount for a prop balancer!
  4. What type of wood did you use? I'll just have to re-read this topic. Interesting stuff. I just figured out now how you used the templates as a reference for your cutting machine. My next question are: How did you get the stations/positions for the profile templates? Are you working from published plans of some sort?
  5. Or imagine you're in a Cozy where a left-hand stick is standard (unless you fly from the right seat). The canard may be a GU so just build a new one if need be. Looks like a great buy!
  6. Impressive Kent. Much of this is just short of magic for me and I can imagine how much research and learning you've had to do if you were not an engineer already (or even if you were)! At worst the 3rd time will be a charm and you'll be a certified prop builder at that point.
  7. Yes, and I'm sure the quality of the strip comes into play. Still, FOD is greater on grass than paved. My recent propeller research taught me that even rain can make a mess of a prop. I would definitely like to fly out of grass strips, but don't plan to in a 4-place canard. Not arguing, but why is this a bigger issue in the Cozy? Weight on the nose? Where are the general aviation "hubs" in New Zealand? Which cities/towns/areas are known for this over others?
  8. Wow!!! I figure those that are building Open-EZs register as Long-EZs, which -- based on a recent discussion on the Cozy Builders list -- would make sense for insurance purposes. Regardless, this is quite interesting. The timing is good too as I am halfway into the Open-EZ Revision 6 update. The FAA registration also brings up a few pet peeves of mine: It's 'Long-EZ', not LongEz, LoneEze, Long Eze, etc. Long-EZ. It's VariEze, with the same points to be made. EZ and Eze are pronounced as if you were to pronounce the letters 'E' and 'Z' individually, or "easy" as a shortcut. </rant> Awesome find Kent!
  9. Pretty pictures, but "yikes" -- a pusher on grass! Obviously not impossible on manicured grass, but problematic with grass of any length and issues of debris being thrown into the prop (which happens with rocks on paved runways as well). Grass runways are generally to be avoided with canard pushers.
  10. Now that is funny! Clean plans are available at www.quickheads.com I much more like the idea of running a Rotax on this, but Onan's were the standard for the original Quickies way back.
  11. Kim, well done with your approved milestone! You just have to do what is necessary. I wonder how much crackling is too much crackling? Thank you for sharing and I look forward to your future updates.
  12. See this thread with Nate sharing information just before and after this plane became airworthy:
  13. Wow, impressive! I assume doing this test is required in Denmark. Luckily we do not have to do that here in the U.S.A., although some still choose to. Congratulations on your milestone!
  14. I took another look at the IVO prop design and found that my initial assumptions were incorrect. It works like the neck adjustment for guitars, where adjusting a screw induces a bend in the neck of the guitar (a twist in the propeller blade in the case of the IVO). I could imagine this being used nicely for infrequent ground adjustments, but not for frequent in-flight adjustments. I am speculating, but I still don't care for the mechanism as a constant speed propeller solution. For my situation, I have decided on a basic climb propeller for initial flights and can move up from there once the front landing gear proves itself (along with the pilot, me).
  15. You can find the build log here, at least starting at the point where Nate picked the project up and took it to completion: http://www.mykitlog.com/users/index.php?user=jenatepilot&project=2121 From that, I'd expect it to be a "stock" Long-EZ and as Andrew points out it's well built, has been flying, improved and actively maintained.
  16. Stumbled on this video from 1985 when Rutan Aircraft Factory was in full swing. The introductions shows a Long-EZ in flight so I assume the builder doing the demos is building an EZ. Grainy and a touch outdated, but I found it to be a great refresher (although I take exception to the suggestion NOT to use gloves -- nitrile gloves may not have been available in '85).
  17. Randy, I'm not Kent but the work is clearly at a high level from the pictures. Many people have seen Nate's plane so you may get other feedback. I'd highly recommend a pre-buy inspection and to fully understand any deviation from the Long-EZ plans specifications and dimensions. For example, how is "Almost double the interior baggage capacity of a plans built long ez." achieved??? Was the airframe widened or lengthened? "Almost double" is a LOT, so what was the trick? There's also this gorgeous plane that does not have the same interior quality, but you could make that happen yourself if so inclined. With $100,000 you can certainly pick between exceptional and gorgeous!
  18. I'm betting that last picture up there is showing upwards of $1,000 in parts.
  19. Not being a weirdo might be a challenge for me. I'll do my best to use knots. I was wondering where the Diameter in your equation was so I reread the article and realized I skipped past the formula parts. I'm collecting information on options to get the plane back in the air and will verify other flying props against the formulas and eventually report back. Thanks!
  20. I stopped in the Engine Tent at Sun-n-Fun and spoke with a Rotary guy involved with the recent FAI time-to-climb record, which was set by a 600+ HP turbo-charged Mazda rotary. The feat and story are both amazing, but was a reminder why I came to the same conclusion as you Quinton. The story alone behind how they acquired a suitable PSRU should be enough to turn people away. They somehow randomly connected with some old piece of military equipment where they were able to adapt the PSRU. Once the record was set they have no plans to fly the plane anymore because it's just too much effort to keep in the air and the overall TBO is probably 50 hours. The specific concern was that someone would kill themselves. The Cozygirrrls are carrying the torch on this, but at best I'd expect -- and I only speculate -- that they MIGHT produce a PSRU but I doubt it. There is no more any good community support for rotary aircraft engines, at least at the level that would work for me. Someone that had engine experience and a machine shop might have results, but not me.
  21. I know someone flying a Warp Drive propeller behind an O-200 on their TriQ-200, which is ground-adjustable. I look at the IVO mechanism and I'm just not comfortable with it (whatever that's worth). At most and for my needs (it's crowded here in north-central New Jersey USA and long runways aren't all that common) ground-adjustable may be the next option if I need it. I probably will put on whatever is economical for first flights. The KOOLprop looks like an IVO, but might have different mechanisms. I don't know. @Kent Tarver is on this forum as well, with a lively discussion of the goings on at Aeromatic in this thread. @Voidhawk9 That makes perfect sense Cameron! Same here in the USA as to why there are so many older pilots -- they all got trained during wars and planes were cheap after WW2 here as well. Thanks for your feedback... I expect to be moving forward with a basic fixed-pitch prop before I invest in a Prince or Catto.
  22. Yes, I understand the motivation was for takeoff performance. The tradeoff is weight and dollars escaping your wallet. With all this in mind I am locking in on fixed pitch. I would never have thought about constant speed if it weren't already on the plane. I'm curious as to how aviation got so well-established in New Zealand. It's one of those pockets in the world where there's a lot of activity. Similar story with Brazil and France.
  23. I was looking at those SprintAero props earlier today. A suped-up O-200 is just about worthy of their SP20a, maybe. I'd also have to move to NZ to make it worthwhile, which wouldn't be the worst thing I could imagine! I know a TriQ-200 pilot flying a ground-adjustable Warp Drive propeller which is reasonably priced so that's an option. I'm also looking at Prince and Catto options which are popular with those flying Q2/200s. I am settling on getting max HP (expecting a touch over 100) with a fixed pitch due to budgetary constraints. Thanks for the feedback!
  24. Here's a free article from Kitplanes magazine titled Firewall Forward: Choosing a Prop for Your Project. Of course you can just ask other flyers what they're using to help decide. I bought a prop-stricken TriQ-200 that had a high-cost MT constant speed electric prop (on a 100HP+ Continental O-200). The refurb cost to that was just shy of $7,000 a few years ago, which led me to plan for changing over to a fixed pitch. Speaking with the original builder, he told me he would have never put the constant speed prop on if he had first installed the high compression pistons for a few extra horsepower. Later, realizing I'd be changing the aircraft, I decided to bite the bullet and keep the existing configuration with the MT to keep the configuration as-was. Flip-flopping still to this day, I would go for an alternative lightweight electric constant speed if I could find something in the $5,000 range. Then again, this thread on the Pilots of America forums makes a good case for moving back to fixed pitch. Just going through this writing exercise has me back in the fixed pitch plan, so thanks for listening!
  25. Sun-n-Fun 2019 flew by faster than ever this year. As usual I tried to fit too much into a short timeframe, which included a vacation with my better half, a visit to Disney (for her), a visit with my sister, Sun-n-Fun, then a tour of Kennedy Space Center on Monday to watch SpaceX's historic production launch of their Falcon Heavy rocket. Well, as soon as we got their we punted Disney which was partly a result of a Palmetto bug in the Airbnb bathroom ('Palmetto bug' is a friendly term for "nasty ass cockroach", and yes, I know they're more common in Florida but they're still nasty). With that we headed from Orlando to St. Pete Beach to see my sister for a night. Next day was off to Sun-n-Fun, where I realized I hadn't planned my agenda (which was partly because I wanted to balance my attention between airplanes and my traveling companion). She was more than accommodating, so by the 2nd day there I was able to see a few things and get into it. What caught my eye this year was the growing number of small avionics companies. A company from Italy caught my eye with an instrument that fits in a standard 3-1/8" hole and can be configured as 1 of 9 possible instruments. I spent quite a bit of time speaking with the vendor and probing the underlying technology, which amounts to custom microcontroller programming with devices connected through an RS-485 bus (as best I could tell). You can find more information from them here: http://www.ifd-net.com/ They want close to $1,000 per primary instrument, but perhaps less for "slave" units (just displays and knobs but without sensors). This strikes me as being expensive compared to other options such as Garmin's G5 electronic flight instrument which is $1,250 new. The benefit of IFD's approach is that their instruments are designed to look like classic instruments without the distractions of this new fangled stuff 😉 (which may be inevitable that we all get used to at some point). Looking back I definitely needed another day to take advantage the free information from various experts and vendors. I was able to relight my motivational fire to get my butt in gear with my shop, more flying time, and figuring out how to attend more fly-ins this year. I took a bunch of pictures and put a few into the Sun-n-Fun 2019 gallery for your viewing pleasure.
