  1. @canamex you might want to add useful load to original post.
  2. Skip, What did you use to create these drawings?
  3. The shipping cart comparison is more odd as the zero axis (axle and contact patch) and steering axis do not intersect.
  4. At no point did any thing I described meet the definition of negative caster with the exception of the shopping cart.
  5. The axel of a bike never is as far as I know. It either aligns with the fork/fork slider or is ahead of it as pictured.
  6. I noticed that it had been registered to the same owner for 18 years, which added to the mystery of the incident.
  7. Perhaps on some bikes, but I don’t think thats the norm. I have restored a few different motorcycles from various eras (Jap and Brit) and all had triple clamps with the fork mounts offset forward of the steering pivot. The axel mount is typically at the center point of the fork. HD springers have less offset at the triple clamp, but the wheel is offset on a swing arm at the bottom of the fork. Many MX bikes have axel mounts offset forward of the fork, which is already offset forward of the triple clamp.
  8. Yes, I think the change happened in 69 or 70. Incidentally, the button lock version on my early F has required little more than lubricant and a new rubber seal every 8-10 years. I expect the cable will be due for replacement in the next 5 years.
  9. LASAR calls for 70+ hours to install the one piece belly on an undamaged plane. Is it fiberglass? Was there a UL penalty?
  10. So what is he disagreement about? I would think that between the IPC (attached) and the damaged parts, it would be pretty straight forward. I have 67F which should be the same. More info would help me capture the details you’re looking for.
  11. Baggage door still intact and was open and in the up position at the crash site. Possible that it went through the crash sequence in that position, but seems more likely that it was opened by first responders.
  12. If you are able to get some info, please report back.
  13. I had not thought about that to be honest. I might give them a call. Looks like Isaac sold his Mooney in 2018. If you look up his N number, you can see his full name, and where the plane was registered during his ownership. Maybe you can track him down and ask.
  14. Much better if you flip them around backwards. They make better tail draggers…
  15. I honestly had no problem opening and closing the door to retrieve the seat belt tail. I don’t remember exactly how I set the airplane up. Maybe trimmed for nose up… this was at least 6 years ago so not fresh in my mind. Just remember that I was expecting it to be a problem and was pleasantly surprised.
  16. Perhaps. Looking at ADSB data from other AC in the area at the time of the accident would give a better idea.
  17. I did not know that “Fantom” had passed. I always wondered what became of him. I enjoyed his aviation insights and his dry sense of humor. How long has he been gone? Seems everyone has had trouble with a door close in flight. I guess I’ll have to make a video demo. Did you and Gary slow down? I’ve never tried it at cruise speed.
  18. It’s pressure altitude so it can be off by hundreds of feet. As much as 300’-500’ off is not uncommon. The inaccuracies are usually consistent throughout a pretty large range of altitudes, e.g. if I level off at 4500 and then climb and level off at 8500 the ADS-b data might show 4760’ and 8775’.
  19. I’ve never had a door pop but I once departed with some seatbelt webbing closed in the door. I had moved the pax seat forward for some reason and the part of the door with the belt tail hanging out was on scurry from view. At some point in the climb, I heard a slapping noise. Took a few seconds to realized what I had done. At about 3k I slowed to 100mias. I then opened the pilot side window (don’t think it mattered one bit given the size of the cabin vents but remember reading about it so I did it). I then unlatched the door, retrieved the seat belt tail and closed the door. It was not difficult at all. I have very good mating between door jam and door (absolutely no leaks) so maybe that helped. As to ASI increase with door opening, you raise an interesting question that leads me to believe that my alternate static source is open. If I open the pilot side window in flight, my indicated altitude jumps about 80ft and my IAS jumps a few knots.
  20. perhaps there is a pressure drop in the cabin affecting IAS? like when opening the pilot side window in flight. Cant imagine it would affect the airfoil much nor the ram air at the pitot. PSA. A door pop does not require a RTB. Door can be closed in level flight with little trouble.
  21. This is a full service forum. Seriously though, imagine trying to steer a motorcycle with the front end configured like a shopping cart...fork out in front with a trailing link and the axel well behind the pivot.
  22. Figure 32 from Factory IPC for 1966 MY Item 12 is the vacuum valve assembly. I may have a spare in my hangar. Service Manual download link at the very bottom PC service Manual here.
  23. If you tried to steer a shopping cart from it's steering pivot point, it would handle horribly.
  24. It’s shown in he Mooney IPC as well as the Brittain maintenance manual. I’ll get copies to you as soon as I am back to my computer.
