Hello, just like you (hopefully) I love the sleek lines of the blackbird, and after building, flying, crashing, and learning how to fly the FT-Viggen and its elevons, I decided to build the black-bird ( Yea I know it's still white in the thumbnail). First I went online to find the original blueprints of the SR-71, traced roughly the top-down profile of the jet and transferred the lines to some sheets of foam, from there it was mostly cut, measure, cut again, shape, then glue. I had an idea of what I wanted to do using simple creases and folds in the flitetest style.
The aspect that I wasted the most foam on were the motor nacelles, MAKE SURE YOU ARE BENDING WITH THE GRAIN. I wasted so many sheets trying to get those just right. The plane is 46 inches wide and 74 inches long, it is powered by two 5-bladed 64mm edfs running on two 50 amp escs off a 4000mah 3s. It does have differential thrust but has yet to be maidened. Sadly there are no plans for this bird yet because I still need to learn how to design planes in cad. I could measure every angle and line but it probably is easier to take all the panels off and trace them, which I don't want to for obvious reasons. However, if Flitetest is interested in helping with getting plans put together then I would gladly work to make them.
After the last large plane I made ( FT-A10) crashed due to wing foldage, I am a bit nervous to get back into the sky with a large project like this one.
Wish me luck,

Edit:
Plans on the way, testing a new model!

With a Thrust to Weight ratio of almost 1.7:1 - an absolute minimum would be 73mm EDFs, with 12 Blades, and 4S Power! 😉

Hopefully, I will finish testing soon and release the plans!

I live relatively close (1.5 hr drive) to the Evergreen Flight Museum who has an SR-71 with a real nice display of one of the engines. (They also have the spouse goose). I have also seen the SR-71 on the floating museum, the "Entrepid", docked in New York.
Up-close or from a distance, the SR-71 is the most beautiful plane ever. The fact that it is also the fastest is just bonus.
