  1. Lots of room on the right you could blow at least ten thousand more in that area ha.

    Ten thousand?  Amateur! :lmao:

  2. I generally load any pictures I want to post in to Microsoft paint first, resize it, usually to 30%, then save the smaller file as whatever it was with _small on the end (before the period).  The small size posts much better.


  3. Either there's a lot of time between those photos, or someone is really good at puzzles!

  4. Well, for some of us going crazy is a very short trip!  No reason to cross state lines for me! :P

  6. Well, if you paint it first, how well it sticks is entirely dependent on how well the paint sticks, since the glue will only be sticking the fairing to the paint.


  7. Great, now I have to get that image out of my mind.

    No worries, I don't wear it, the housekeepers I hire do.  Trust me, its not a bad image to have :lmao: 

    :BC:

     

    No worries, I googled 'French maid outfit' and got enough eye bleach to erase the mental image :biker2:

  8. Maybe, but I want to live more than 2 weeks personally.  They also didn't have to deal with crosswinds - Aerodromes (big round fields) not airports.

    Quote from Wikipedia:

     One man asked to be moved back to his infantry unit, where "he could be safe." 

     


  9. For airplanes, HP is the best gauge - the engine will spend most of the time working at or near peak HP, so it doesn't matter how it gets there - High RPM/low torque, or Low RPM/High torque.  Low RPM/High torque means you may not need a gearbox, which can have some advantages, but those engines usually weigh more so the advantage is primarily in simplicity.

    If you are pulling train cars, stumps, multiton trailers, or drag racing, torque wins every time.  If you are oval racing, HP is usually the king, unless you don't have enough aero to take the corners at close to full throttle.  Road courses need a balance.

  10. Neither ILS nor VOR's are going away.  There will be fewer VOR's, but the FAA has established a minimum set that will be maintained indefinitely that will enable navigation across the US if GPS is out of service or degraded.

    There won't be any new ILS approaches, they are too expensive to install and maintain compared with an LPV approach.  I also wouldn't be surprised if some smaller airports with limited commercial traffic get decommissioned when they become too expensive to maintain.  But the major airports will continue to have them for the same reason.

    ADF's however, have definitely joined the Dodo bird in history.  A few are still out there, but when they need major maintenance they are decommissioned.  I liked ADF approaches, but time and technology marches on.

  11. They indicate on the page the picture is just and example of the aircraft type, and state that the pictured aircraft is not UL powered.

    They do have a firewall forward package for the Avid.  I priced it a few years ago, and it was around $18,000 as I recall


  12. There would have to be a LOT of excess resin for that to happen!  The biggest hazard of wet layups is weight.  One of my other (very) long term projects is building a Cozy (Rutan Canard).  Since the entire airplane is moldless layups, even a little excess resin on each layup can add up to a lot of extra weight.  Excessively wet layups mean the part is too heavy, but usable.  Post cure evidence of a dry layup (white spots usually) means you either remake the part if possible, or cut out the dry section and repair it.

     


  13. I have followed UL engines.  They look great, and have good weight/power ratios.  They aren't cheap, but then neither is a 912.  If I was considering a 912, I'd definitely consider the UL engine.


  14. Wow, usually it is too much resin making fiberglass or carbon weak. Sounds like they weren’t attached well either. 

    Dry layups are much worse than overly wet ones.  Overly wet ones are just excessively heavy, but not dangerous.  Overly dry, the glass/carbon layers work independently instead of as a unit and are only as strong as the strongest layer, which in compression is basically zero.


  15. That only works if the two circuits are on different 'legs' of the incoming service.  Household single phase breaker boxes are designed so that adjacent circuit breakers are on different legs, that's why a 220v breaker covers two positions.  Hooking up to two breakers that are on the same leg will still just result in 110v.  You can't make 440/480v from a household single phase service, I don't care how many breakers you connect.  440/480v generally requires 3 phase commercial service, and that voltage is on each of the 3 legs.

    USA A/C power is 60hz, which it means it oscillates between + the rated voltage and - the rated voltage 60 times per second, so 110v oscillates between +110v and -110v 60 times per second.

    Single Phase household service has two 110 volt (nominal) legs.  The phase on these two legs are 180 degrees out of phase, so when one is at +110v, the other is at -110v, the difference between the two is 220v, and that's how you get 220v in a household single phase service.  Without a transformer, you will never get any more voltage than that.
