  1. Early wing design too by the look of it. Wow, a rare bird indeed!
  2. Tricky, but not impossible. For as new type of conversion, mounting it on something slow and rugged would be a safer start. If it is a 'proven' conversion, then by all means. Just know what you are getting into, but this is experimental aviation, after all.
  3. Always nice to spot a canard! Posts can be edited, but only within a limited timeframe after posting. This prevents malicious editing later, which happens in some places (not here that I am aware of).
  4. Build log is broken - on the to-do list! I haven't found the distance from other canard builders to be a big deal. Online support is really good and with a little research most things can be figured out.
  5. Nate Mullins has the UL powered EZ, and he did resolve the issues eventually. He can provide guidance regarding installing them in an EZ if you want it.
  6. Hi Larry. I'm in New Zealand, not Thailand, but we share some similar problems. I'm building a (modified) Cozy IV, but haven't ever flown a Cozy. I did get to see a couple and fly in a Berkut and Velocity while in the States a couple of months ago (pandemic spamdemic!). If the design / configuration is one that excites you and you have a passion to build, go for it! It is a lot more time and effort than one of those kits, but to me it's worth it - I look forward to flying it very much, but I really enjoy the building too! I'm 6'4", and am confident I can build the canopy to suit. I have sourced equivalent materials here for much of the raw stock. Foam, BID, epoxy, no problem. Hardware, Cozy-specific parts, and UNI glass I have imported from the USA so far, though I haven't had to get any 'big' parts yet. Colan in Australia has some some good glass options, and I believe is the new spar tape supplier for Spruce anyway. You're clearly the 'builder' type. Have you done much composite work yet? I hadn't, so I did a couple of small projects with the stuff first to make sure I enjoyed it. I did!
  7. $400 for baffles being worthwhile depends where you are in your trade-offs between time and money, right? Looks like a nice kit.
  8. Well, that's the point I guess. Still, sounds like Izzy saved you a lot of money and headaches, you won't regret getting good advice like that.
  9. The study uses are Reynolds number of 1000. The Reynolds number on our use cases is in the millions. Not really applicable. Varying the inlet has been shown to provide little or no gain for cooling, provided it is large enough to begin with. Varying the exit does help, but mainly to reduce drag when you are going fast and flow is enough with the exit reduced. The keys, as Kent has shown many times, are pressure differential (ie flow will actually move from inlet to outlet - you may be surprised how unwilling it is to do so in the somewhat chaotic flows at the aft end of these airplanes) and ensuring the air only goes where it needs to with proper working baffles.
  10. 1135 with a -360 in the back doesn't sound so bad. If you're willing to share some photos of the bird, plenty of people (such as myself) are always interested to see.
  11. Thanks! Is that wide-set gear SQ standard? I've only seen that once before on the Stagger-EZ, but I may have missed it. What is the fuel capacity with the smaller strakes?
  12. Here's another method that I copied. Works great! http://berkut13.com/sucker.htm
  13. Looks really nice, Kevin. If you feel inclined to share more photos and information, myself and I'm sure others would be interested to see! The SQ is a rare bird!
  14. 'They' told us it was impossible. Turns out it's perfectly possible if you set your mind to it. Much like building your own airplane. Yeah, it's hot. It's winter back home - not missing that!!
  15. We're spending most of our time in SW Michigan, but presently in Georgia as part of a road trip that took us as far south as Orlando, FL. Took the kids to LegoLand, you see. No queues there at present!
  16. Today I transferred funds to my dedicated project account. I've accumulated enough there to keep me going for some time building airframe. Being that I am travelling in the USA at the moment, I'm not getting much building done, but I am getting a lot of inspiration visiting other builders and flyers!
  17. Another consideration is that the prop creates a pressure wave (it is a wing after all) that briefly blocks airflow flowing past it. Look at most props near the root where our cowl exits are; it is thick and rounded, it isn't moving much air back from the cowl exits! Apparently having the cowl opening further away (cut back away from the prop) reduces this issue. Air being a fluid will always flow via the least restrictive route (thus the need for baffles to force it through the cooling fins). And, it will flow from high to low pressure. If there is high pressure at your exit for any reason (and the aft end of bodies can be a bit chaotic in this regard), flow will be reduced. It might be interesting to experiment with a small 'flap' sticking outwards at the cowl exit to induce a low pressure behind it as a dignostic tool to determine if this makes a notable difference. If there is constriction on the flow, it will slow or stop entirely. As an illustration, open a door (or window) on each side of your house (or other closed in building) on a windy day with the wind blowing towards one opening. Varying the opening of the exit side will clearly throttle the flow through the house. As Barry noted as well, the air gets heated on the way through, so there is a greater volume to exit than enter!
  18. Hey Howard, welcome to the Canardzone. GlaStars look really nice, though I haven't had the pleasure of flying one myself yet. Certainly a different category to the canards! Had planned on lots of canard exposure myself at Osh and Rough River this year, but due to the Current Circumstances I will miss both. But there are a lot of friendly canard guys around willing to share!

    H-250 Foam

    I'd call that an early win!
  20. 2. Don't move house every 12 months, it takes a long time to get the workshop set up and functioning again!
  21. It isn't really US carriers that are the concern, nor here in NZ. It is the places that put pilots with absolutely minimum time and experience in the cockpit, and especially those people when they move up to captains and have someone with equally little experience beside them. So many pilot 'sausage factories' teach to pass the exams (even to the extent of memorizing question banks), not to create the best pilots.
  22. Hi Tim, congratulations on the decision. Keep us updated on your progress!

    H-250 Foam

    I couldn't get the 250 either. I did some research and determined that 200kg/m2 PVC should be adequate, so that is what I used. Near substitution is a necessity sometimes when you live half the world away from the usual suppliers, but it is 'at your own risk'.
  24. Between this and the PIA A320 crash recently, there have been some truly shocking pilot error accidents of late. There are those that have been predicting this sort of thing for some time given the changes to training and hiring practices in the last decade or so. Maybe related, maybe not, but I cannot help but wonder... Maybe these are isolated, freak accidents, or maybe we will be seeing more of these sorts of accidents in the years to come.
