  1. As a Douglas DC-3 / C-47 nut, I really enjoyed Drew's build.  Last night I felt lucky to see this build in person at our monthly Club meeting.  As good as the pictures are, they just don't do his work justice.  The detail work Drew added, the insane riveting detail, the corrections made and - of course - the fantastic effort getting the faded paint work juuuust right make this an IPMS Nationals strong contender.

     

    Just WOW!!

  2. Lee,

     

    You need to answer your own question by going back to before PAGE 21 where all Oliver did was build the H-34 with incredible detail.  At that point he started on the "supporting characters" of the diorama.

  3. Drew,

     

    The "wires" in front of the direct vision portion of the windshield are actually tubing to spray alcohol on the panes as anti-icing.  A small tank above and behind the pilot's head held the alcohol and a hand pump was used to squirt it onto the smaller (direct view) panel.  This was for anti-ice (prevention), not de-ice (removal) so you had to be proactive with its' use.

     

    Again, as usual, GREAT work!

    " Remember there is a step when you install the slat mechanism on the TOP wing. This makes room for the slat to be flushed with the top wing when retracted."

     

    There should NOT be a step where the trailing edge of the slat meets the wing top surface.  At this point the training edge of the slat is only about 0.025".

    If there were a step, there would be major aerodynamic disruption across most of the wing at slow speeds (slats open).  Model companies mold their slatted wings this way because they can't mold the trailing edges of the slats thin enough if you wanted slats retracted.

    All anyone has to do, if they see something worth mentioning, is to privately message the guy building and send their suggestion to him and him alone. 

     

    Thank you for stating what was going through my mind.

  6. Simple answer from me: I don't know.

     

    I've looked at my OS2U pictures and a wide selection on the interweb.  It is NOT on all OS2U's - maybe only the -3 version?  It is not represented on the Pensacola, BB North Carolina, Cuba or Chile.  It runs from the vicinity of the main fuel tank and curves around the leading edge of the wing and terminates at the forward float strut attachment.

     

    Two thoughts I've had, but discarded:

     

    1) Cable run inside a tube (to prevent "flapping") that runs to pin(s) to jettison the wingtip floats.  A) Why?  B) Only goes to one attach point.

    2) A fuel line from aux tank(s) in the wingtip floats to the main tank.  I see absolutely NO evidence of fuel being carried in the floats.

     

    I'll be interested when we discover the answer.  Maybe someone has access to OS2U manuals?  The old Squadron/Signal "In Action" book?

  7. I think the answer is "it depends".  In the link provided above, the 4th from last picture shows XMU-470/A guns all pointing out "windows".  The last picture shows the aft most XMU-470/A is pointing out the door.

     

    The DC-3 / C-47 was not manufactured with a window one frame forward of the door.  This space was just the same as the spaces where there WAS a window, so cutting one in was not a problem.

  8. I envy your flight time in the DC-3.  While you would know better, each of those appear to be DC-3's, NOT C-47's as evidenced by the "air stair" style entry doors.  N80E is obviously an ex- Federal Aviation Administration (maybe flight check) aircraft and N222TS may have been an American Airlines "Flagship" owing to the right hand entry door.

     

    Please keep us appraised of your progress.
