  1. Hi M6A1,

     

    Part of their criteria is ALL parts of aircraft are to be marked with ID.,

     

    I marked mine with the "Interim registration number" 10-1103, And painted rego no., on wings / fuselage.

     

    I suppose I could hand stamp big X's over every part I've machine stamped.

     

    then what, be told to identify all the bits again,

     

    they never said anything about "wing loads" before building, & there was "Terry Hinze" flying his legally under the 10-xxxx.

     

    so never thought there was any problem with the "HummelBird" design.

     

    16 builders were on my build list in Australia. I don't know any going to 19 or 24 /10- 95/55

     

    And to wait for the builder to finish, and try to get full registration !.

  2. BIG thank you, Jetboy.

     

    That link is fascinating. Will have to pull out my box of HP manual's, plugins, and programs, to see if any of it has survived, being stored away for such a long time.

     

    Every-one thought I was crazy buying such a very expensive calculator, now they're worth as much as the new price,

     

    ( so I bought another one, c & cv. )

  3. OLDK,

     

    The Hp 41 that the astronauts used, wasn't a GPS dependent but could still put you on to the Rumb-line, or do the ded-reckoning and lots of other nav calculations.

     

    The big snag here is getting the N type batteries. the keypad doesn't have an equal sign, the input makes that key obsolete.

  4. Hi,

     

    You do realize there's more ships sunk do to the "lodestone" compass than anything else.

     

    For the weight of the compass you can have multiple backup GPS gadgets, the men who went to the moon had two HP 41 calculators in their pockets, and they didn't miss their target.
