You might consider "source grading" your drawings:

This idea is being picked up by a few other authors (Robert Godwin, Dennis R. Jenkins).

The information I used for this drawing was published by Alain Pelletier in his book "Les Ailes Volantes"
(The Flying Wings) ,ETAI publishing,1998
Como muchos de mis dibujos debe ser clasificado como "Hypothetical reconstruction"

No problem

The same drawing was published at Pelletier's Minidocavia Nº7 "Les Chasseurs Navals Américains" (2ème partie)

Very nice Tailspin Turtle - thanks for posting!

My Father flew F4D-1 Skyrays with VF-23 and VF(AW)-3 so anything in the Skyray lineage is interesting to me.

Enjoy the Day! Mark

It looks like an evolution from the Lippisch P.11 an Me P.1111 (source grading 3) wartime projects.

Can you read off the dimensions on that (span & length)?

Unfortunately, that drawing is in Connecticut and I'm in Texas for a couple of months. However, this is a pretty good trace of the original and the span is readable:

I was wrong again. I found a copy on one of the drives I brought down. The wingspan is 37' 6" and the length is 38' 3".

Thanks! Now I can properly scale it to 1/72...

Greetings All -

Years ago I received a number of Skyray related drawings from Harry Gann at McDonnell Douglas and this past weekend finally uncovered them while sorting thru some boxes I have had stored. I'll scan the rest soon but here is the D-571 drawings - the beginning of the design evolution that led to the F4D and then F5D.

Enjoy the Day! Mark

Greetings All -

Here are drawings of D571-4, note it's a tail dragger much as the early A3D designs were.

Enjoy the Day! Mark

I have one drawing that shows 5 D-571 designs but does not give a -X number for any of them - I've referred to them by the alphabetical designation for now. Note A-B designs use two J-35s whereas the single engine designs C-D-E use either an XJ-40 or a GE TG-190. Still all taildraggers....

Enjoy the Day! Mark
