Paul, I don't know for sure what overflowed the last attempt at this.
Gmail showed a 15 MB limit and the file was 12.3 MB. The yahoo limit
shows 10 MB so I went to deleting again and got it below 6MB by
eliminating the derivation of the design, inserted raster immages and
anything duplicated. If you get this as usual-no rights reserved- copy,
redistribute ,  all or any part that can help anyone. The airframe
drawing when pared down this way is still 108MB. If you want this
data_no rights rederved-of course let me know a mailing address and I
will send a cd by snail mail. The airframe was entered in X-plane at
sun-n-fun
2008 by Alex Portalatin at the computer workshop using only 700HP and
was extremely stable except for too fast a roll rate at full stop
aleiron inputs and with travel stops that was solved. at idle power it
will come down but any attempt at dumping altitude to land speed goes
uncomfortably fast and it floats forever. I am considering
  adding spoilers on the wing upper surface which has not yet been added
to the drawings while I sort out the 6 rotor but if you want a copy of
the current design send me a mailing address.

It was a five meg dwg. I tried loading it into two cad programs. Rhino
could not read it and the other one Qcad will only accepted dxf.
What cad program are you using?
Can it export dxf, iges or stp files?

The other thing you can try is screen captures.
press the function pri scr key upper right on the key board. Load MS
Paint and paste into MS Paint then save as a jpg.

If you use Linux the screen capture program saves directly to a png file
which is almost the same as a jpg as most graphic programs and read it
directly. I think the Mac does something similar but I don't know how to
use it.

If that does not work take a picture of the screen with a digital
cameras and send that as a jpg.
Here is an example of that last trick.

I'd love to see that dwg.

Is a 1984 naturally asp.12A suitable for aircraft use. If so how much Hp.
could be expected?
Steve Hudson

In p-port form my guess is about 230 HP at 7500 RPM.
