  1. Nonsense. The FAA and industry, have been addressing safety using the very method you claim does not work. That is, looking at the causes of the most crashes, then actively working to reduce that risk. They actively avoid 'low hanging fruit' and go for the worst issues first. The result has been the safest airspace in the world. The FAA publishes good information, it's a great tool for us. https://www.faa.gov/news/fact_sheets/news_story.cfm?newsId=21274#:~:text=Loss of control remains the,accidents involving amateur-built aircraft.

  2. It's been a decade since I've looked carefully into the statistics. Back then, single engine, amateur built aircraft had a 6x hourly crash rate, vs their type certificated counterparts. Unfortunately, the hours were estimated. More careful examination really did not help the cause of amateur built experimental aircraft. As they tend to fly far fewer hours and much shorter trips. Whether it's 4 to 1, or 10 to 1 depends on how data is chosen.
  3. I work in high end corporate aviation and have some minor involvement in smaller aircraft GA. I lost 3 friends in crashes in the last 2 years. 1) Joe crashed his OV-1 Mohawk at the SUA Airshow practice (looks to be a broken elevator cable) 2) Guy crashed somebody else’s Wheeler Express (unknown cause, speculation, he may have been doing aerobatics and blacked out) (control integrity was verified and he was observed doing rolls) 3) Dan crashed an Aerostar due to misfueling I’ve also known others in the past who crashed and died. 2 friends died in Midget Mustangs within mo
  4. I use daily contacts that are about +1/4 diopter (or a touch more) too powerful. I wear them all the time. As we age, our focus accommodation reduces from 10 diopter to about 1 diopter at age 50. It’s possible to utilize optics to “bracket” the accommodation you still have and be able to see relatively near and far with good clarity. This is not for everybody and it does take about 2 to 3 weeks for the eyes to adjust to a different “distance” focus. But the end result has been 15 years of not needing reading glasses. (For all but the smallest of things) I’m 57 I’m finally get
  5. The RV8 is a fairly comfortable fit for a normal sized pilot and in my opinion, far too tight for normal sized men as passengers, as the passengers feet fit in a little area on either side of the pilots seat. Once you are in, there is not much room to move around, stretch your knees and no possibility to reposition the seat. As mentioned above, they are configured before flight for the pilots size. They fly very well, can be quite economical to operate and the performance is excellent, even on lower HP engines. In some ways, I like the side by side RV’s better, as there is more wiggle r
  6. I picked up my Norwegian Elkhound at 8 weeks old, in Ohio. She's been flying with me ever since. As a young pup, she needed to be in a crate. As she aged, she calmed down and can be free in the plane. She knows to look for the runway, once we are in the pattern, and gets excited when she sees it. That's kind of cool. However, it's good to know that some dogs can't handle the same high altitudes that people do. I've been flying with dogs for many years and none of my dogs have ever been alert over about 10,000 feet. Even my super fit and healthy Siberian Husky was out like a light at 10K.
  7. I'll take the Pilatus, it's actually designed for such operation. We operate a PC-12 NG, it's an amazing plane.
  8. Our flight department operates a 1998 Extra 300L aerobatic plane with just over 200 hours on it. At the 20 year mark, one of the condensers finally failed and the magneto produced unsteady performance. It took 20 years before any problems cropped up, and even then, it was a simple fix.
  9. I'm a big fan of properly accomplished field overhauls. Using the existing crankshaft without prop strike history... Owners can source engine parts themselves and then hire a capable A+P or local engine shop to do the work. Years ago, I was able to get a 10% discount for a bulk order of engine parts. Worked out really well and they even honored one bad connecting rod bolt that refused to stretch. Here is my IO360 while I was performing the field overhaul. Also, I wanted to give a "thumbs up" to Barrett Precision Engines in Tulsa. I had them build an engine for me and I
  10. In the past, I've laid out the many positive reasons for ownership. Many of which are touched on above. But, it boils down to the fact that shared expenses only work with extremely like minded individuals. Otherwise, MX expenses skyrocket, as none of the multiple owners will do any preventive work, or even employ any cost saving measures. There is incentive to find "the best/fastest nearby shop" (read, most expensive) . For shared ownership (club, partnership or shares) to be financially viable, everyone involved in owning and operating the plane must make a profit. Individual owne
  11. Walter Extra's EA-300 electric stunt plane set a world speed record of 210 MPH. We operate a "conventional" Extra 300L, with a BPE engine and an experimental 4 bladed MT prop (wider cord 3 blade blades on a 4 blade hub). It's top speed at sea level is an indicated 182Kts. Or 209.3 MPH. I'm impressed that the electric version of the plane can actually match our speeds. Of course, the electric plane can do it for 5 minutes and we can do it for 2 hours.
  12. As you probably know, there are already a few local agencies with Tesla patrol cars. They are really good for that application as there is enough range to complete a shift. Initial cost is a factor as police cars are often competitively priced. The savings on fuel and maintenance costs do add up over time. Time will tell whether it actually evens out. Some of these areas don't have cheap electricity. One "internet" famous car chase had to be terminated because the battery died... but they failed to charge it before the patrol. https://www.extremetech.com/extreme/299166-cops-abandon-high-
  13. No, not my world. I work for an exceedingly wealthy individual as Director of Maintenance in his corporate flight department.
  14. One thing NASA has noticed with certain designs using electric drive is the ability to eliminate the variable pitch prop. Instead, designing for low RPM on takeoff and climbout and high RPM in cruise flight. The benefit is low noise at the airport and fewer moving parts.
  15. 1) Is not as true as many of us had hoped. Tesla is packing more and more cells into ever larger battery packs, giving the illusion of improvement. The 150WH per KG reality remains pretty steady in real world applications. Example: The upcoming 100KWH battery for the Model 3 is going to provide 400 miles of "non highway" range. Nobody mentions that it's twice as heavy as the Base Model 3's 50KWH battery. In fact, the 100KWH battery is so heavy, the Model 3 is going to be modified to carry the weight. 2) Correct, moving power requires substantial cable runs. In the electric Extra 300, the
