  1. Heck, we have our own Hornet STOL for that: https://aircraftkits.com.au/blank-2/ (Easily bored? Go straight to 4:06 ;- ) And across the ditch even Skyrangers get into it:
  2. This guy took his sister for a fly ... she seemed to be enjoying the whole thing immensely, until ...
  3. Ha, ha ... where is it, anyway, Wal? Somewhere between Kabul and Tranquility Base?
  4. That's good to know. It set me a googlin' to discover if an old Garmin GPS 12 I have hanging around could still be expected to work. This is what Garmin says: Garmin Support Center GPS 12 Time and Date are Incorrect We’ve identified an issue with this product that causes the date and/or time to be wrong after the GPS Rollover on April 6th, 2019. However, all functions not dependent on date and/or time will continue to work normally. Due to the age of the device we have determined we will not fix this issue. What does that mean for my Garmin? The date and/or time determined by the GPS will be wrong Position, velocity, navigation, and all other functionality not dependent on date and/or time will continue to work normally What is GPS Week Rollover? The GPS satellite system communicates the date via a week number that is limited to 1024 weeks (about 20 years). On April 6th, 2019 the week numbers broadcast by the satellites will “rollover” to zero. If GPS receivers don’t account for this rollover in their software, it will calculate the wrong date and/or time.
  5. I'm not sure if these make it much clearer than the pics already posted. They're just a couple of clips taken last year of Pylon500 at work on some other of his projects. However, the subject of this thread (his original design for planet47) can also be seen. In the first shot we pan past it from the front. In the second clip, it can be seen from the rear in the background as Pylon tells me about the almost finished wings of that other project on-the-go. front view.m4v rear view .m4v
  6. The writer of this article in Aviation Safety Mag seems to agree. His essay is long and detailed and deserves to be read in full, but I excerpt a few bits to indicate the drift. What a Pushover Unloading the wing can prevent a stall or spin, but only if you're aggressive enough https://www.aviationsafetymagazine.com/features/what-a-pushover/ " .... // If the airspeed is rapidly approaching stall speed, even with full power, you need to act aggressively in getting the nose down, and this may require unloading the wing to 0 g. You can prevent a stall and maintain some measure of control. If a crash is inevitable, it is better to crash wings level with some control than to crash out of control and with the airplane in a bank. .... // The altitude loss that results from such an aggressive pushover is not much greater than in a normal stall recovery, but by unloading the wing you will prevent both a stall and a possible spin.You will be able to continue flying the airplane until the recovery is complete, and not experience a momentary loss of control as in a full stall or spin entry. .... // ... when the airspeed is bleeding off rapidly, aggressively pushing the airplane over to a 0 g state will keep you from stalling and spinning. It retains your lateral control and gives the airplane higher acceleration or slower deceleration until you can get the airplane flying normally again. Wing loading may seem like the province of aeronautical engineers, but knowing the dynamics of reducing the load may give you the ammunition you need to kill a low-altitude stall/spin before it happens." by Michael Friese Michael Friese is an ATP, CFII and airframe mechanic. He is a former assistant chief pilot at Embry-Riddle and currently flies for the U.S. government. And, right on cue, unfortunately, another illustration ... and similar analysis and advice from Blancolirio.
  7. Some interesting recent vids on the topic
  8. STOL Pilot Warned To ‘Lower Your Nose’ Before Crash By Russ Niles Published:June 1, 2022 https://www.avweb.com/aviation-news/stol-pilot-warned-to-lower-your-nose-before-crash/ https://www.youtube.com/shorts/Ch3o26Y5_0E
  9. Speaking of WX; this recent AvWeb article is a good read (needs some down-under adjustment, of course) Weather Deconstructed As a kid, did you ever take something apart to see how it worked? Let’s do that with the atmosphere to better understand it. By Tim Vasquez Published:May 30, 2022 https://www.avweb.com/flight-safety/risk-management/weather-deconstructed/
  10. I'm not sure but if the earlier posts in this thread still apply it looks like you can. I wonder if they're still being made in Gympie.
  11. We can lose it coming, and we can lose it going ... and sometimes be lucky enough to get away with it, anyway. But if the second one had have been 'fiery' then the outcome would have been dire. As usual, lots of interesting discussion in the YT comments. "Watch on YouTube" to see them.
  12. I see that the Aussie Aeropup is now being made in the USA: Fielden Aero • Home of Aeropup USA USA https://www.fieldenaero.com/ Brochure: https://www.fieldenaero.com/_files/ugd/f1dfaa_21e0c50e0ded415f8dc6985008ef0e64.pdf This is an interesting posted comment on the YouTube video above: R Barnard 9 days ago (edited) I think this is the right way to go. A solid platform designed for easy maintenance ("easy" means it'll be more likely to get done on time, translating to safety). A design that trades a couple extra pounds and a little extra drag for safety, durability, maintainability, utility, and economy....without exotic materials or technology at its core. Steele is strong, durable, can absorb a lot of energy when it's being deformed, and will often bitch loudly to anyone paying attention when it's failing (i.e. doesn't tend to fail catastrophically). Adding a smart flight adjustable prop and pairing it with a modern engine, fuel injection, and (redundant) ignition and engine management firmware makes good sense (IMHO) as it is now well proven to be reliable and performant. It also allows for data recording which can be used to spot trends, and help diagnose issues and potential issues. Leveraging modern electronics for trim servos, navigation, and to help with awareness and simplify the pilot's workload is another great move. There isn't a replacement for proficiency, but amateur pilot's (for the most part) will always lack the skills and proficiency of professional pilots (yet we all want to build and fly an F-18 or a Warthog). Making an aircraft that builds in a fare amount of safety margin, remains approachable in multiple aspects (costs, maintenance, storage, etc), and provides utility beyond the $100 hamburger seems a more comfortable and obtainable dream. Regarding proficiency... I like to ride motorcycles, which is viewed by many as a risky activity. In fact, a motorcyclist is at risk of serious injury at a rate of 25 time greater that car drivers. Therefore I try to ride every day (here in the Atlanta Metro area), to maintain proficiency. So far (and knock on wood), it seems to work. This is how I manage the risk.
  13. I think this is the one you mean Thruster. Yeah, an interesting suite of engine problems, trouble-shootings and seeming solutions:
