Hi mldixon,
Looks great! Kind of curious if you have some three views of the d-21 you used to do your rendering? I only had some photos to use, haven't been able to find a 3-vu anywhere. I have some photos I took of the M-21 Blackbird and D-21 at the Seattle Museum of Flight. Not very good perspective, but if you need any I would be happy to send you them. Although they recovered hardly any of the canisters, several were launched from B-52's after Kelly Johnson ended the program. Launching them from the M-21 Blackbirds was canceled when one was lost with a pilot. In his book, Ben Rich says that this is the worlds most efficient aerodynamics aircraft. Best regards, Mike Bauer |

Try this link for a good three view image. http://www.donsmodelworks.com/wmprods/images/wm72076.jpg Thanks for the offer of additional material but to be honest with you I have hard drive overload already on this one.

After questioning him for several minutes, I learned a lot about the aircraft, and what it could do, and also that it had recently been quietly declassified. I recall reading somewhere about one of the drones being found in either China or the old Soviet Union. They was a bit of confusion as to what it was and where it came from. I think I would have been somewhat confused if one morning, one of them appeared in my backyard. 8v)

PLA Retired Gen. admitted China once got D-21 Drone in 1971|China Military Power Mashup Pictures of the Chinesse standing over the recovered drone. Also the Russians recoverd one and gave the pieces back to a Diplomat. They also developed one by reverse engineering the recovered drone, but never produced it.? Maybe. ? Who knows for sure? |

Those curved trails behind the SR71. Are they there because of the curved atmospheric flightpath where it is so high in the stratosphere? Are they there from the fish-eye of the camera lens? or are they there because the SR71 is trying to create more uplift force on the drone?

" Unfortunately, the drone was not able to penetrate the shock wave coming off the mother-ship. The D-21 (#504) had almost cleared the M-21's rudders when it encountered the shock wave, bounced off, rolled 45 degrees to the port (left) side, and impacted the mother-ship almost directly at Station 715, where the forward fuselage attaches to the wing root. Between the impact and resulting explosion, #941 was for all intents and purposes cut cleanly in two." |

First unfolds Mock up
Here are some pics of the first unfold of the white model. UV mapping next. Formers need some fine tuning. Tail just added quickly as I have not attacked that for true form yet.

Your further along than I am. I currently did a test piece to check on the profile. I like this little drone because it is very aerodynamic. The initial test looks good, did it with typing paper. Should have used card stock, but this is just a test. I am using descriptive geometry (and trig) to figure all the curves and angles (old school). I will confirm with program in the next few days. Hope you like.
