That's pretty amazing, however, the title is a bit misleading. He made an RC Blackbird replica: not a drone, not life-size, not immune to radar, not weaponized, thus not a Blackbird.

That is just amazing. When I was a kid, I loved to read about high-tech aircraft and space ships and I recall that the SR-71 was known for being hard to handle at low velocities and altitudes (something about the shape of the plane). I wonder if the same is true about the small version. It looks easy enough in the video.

I think calling it a drone is a bit misleading. It's a radio controlled model aircraft.
shazow 14y ago
Wow, the most impressive thing is that he actually managed to land it while controlling remotely. That must have taken a lot of experience and skill. I'd feel more comfortable writing some autopilot landing code for the thing than to trust myself to not ruin months of work.

  Remote control aircraft hobbyists get pretty used to weeks/months worth of work smashing into trees, the ground, etc. That's why you start off on the small, cheap projects first.

Impressive. My initial reaction watching the clip is that he got the sound right (loud). I've stood near the runway as a real Blackbird took off and could feel my chest rattle from the sound as it rolled by.

I highly recommend a visit to the Museum of Flight in Seattle where you can see a real SR-71 Blackbird. It doesn't look like it came from this planet, gave me the chills thinking about the people who created it.

  > I highly recommend a visit to the Museum of Flight in Seattle where you can see a real SR-71 Blackbird There's also one at the Pima Air and Space museum, near Tucson, AZ. Considering that and a minuteman silo are the only things worth seeing within 100 miles of Tucson (kidding, but not by much, the "Landmarks of Tucson" article on wikipedia is 10 entries long, with 3 entries actually in Tucson), I'd recommend keeping it for when you need to go to this hellhole, and doing more interesting things in or around Seattle.

  Or when they created it. The first manned flight was in 1903. In less than sixty years we had this plane. That's unbelievable.
  - ortusdux 14y ago
    Few things about that plane that are not amazing. There is an engine on display at the aforementioned exhibit in Seattle. Every tube on the outside runs in a 'Z' configuration instead of just a straight line, because the engine grows 6 inches longer at full operational temperature.

    What's more unbelievable? After 48 years we don't have anything that comes close to it and we don't even fly them anymore.

  The Strategic Air and Space Museum in Ashland Nebraska has one as well.

There are many RC models of unique aircraft. Here's one based off the Horten brothers' flying parabola: http://static.rcgroups.net/forums/attachments/1/6/2/3/6/1/a1390320-156-Horten%20Parabola%20Aerotow2007.jpg?d=1184348723 http://static.rcgroups.net/forums/attachments/1/6/2/3/6/1/a1.... The Hortens were WW2 german aircraft designers who specialized in flying wings. This RC SR-71 of course doesn't implement the most technically challenging features of the actual aircraft: ramjet propulsion and titanium skin. It's a very cool looking toy though.

  (Also its top speed and flight ceiling, the handling of which posed unique challenges for the time)
runjake 14y ago
"Drone" implies autonomous, or pre-programmed planned flight. This is an RC aircraft. Cool, nonetheless.
- __float 14y ago
  This was my immediate reaction as well. But with a bit of consideration, I don't really think this is the case. Interesting connotation though.

There is no need to capitalize the word garage in the title. Also, the title should indicate this is a video.

I'm surprised the aerodynamics work at scale and slow speed. Very nice work! (Incidentally, I'm always amazed at the eyesight these guys seem to have, I'd have no idea which way it was pointed)
- watmough 14y ago
  If you have enough power, almost anything will fly. $100 (US foam kit, order electronics etc., straight from HobbyKing in Hong Kong) or so and few evenings work and you can make something like this... http://www.youtube.com/watch?v=NPATzx-Nx-4 http://www.youtube.com/watch?v=NPATzx-Nx-4 Just google for 3D foamies, I have one and it's enormous fun. Can be flown like a regular r/c aircraft also, not just for stunts, and they will carry keyring cameras easily, just tape it on.

    My personal favorite flying oddities are the lawnmowers: http://www.youtube.com/watch?v=kNWfqVWC2KI http://www.youtube.com/watch?v=kNWfqVWC2KI The reason that the SR-71 surprised me is that it seems like it doesn't have that much wing area (which is probably somewhat counterintuitive given the length), and it wasn't flying at a significant upward angle like those foamies.
    - watmough 14y ago
      Ahhh, if I remember right, the whole thing is basically a wing, and will fly at some slight positive angle of attack. As far as the model goes, it is probably constructed to be extremely light. It certainly appeared to have quite sprightly performance, implying lightness, since ducted fans aren't known for their especially high thrust.

Such a beautiful plane. I got the chance to see the second to the last flight of the NASA SR-71 at Edwards AFB in I think 2001 or 2000. The airplane is other worldly, loud as hell and simply beautiful. They did a full Mach 3 overhead pass (at 50k feet I think) and also a bunch of slow and high speed passes before it landed and it did a close up crowd taxi-by. The engines at idle have a unique noise, different than any other jet they had. From the front its a higher pitch noise due to the fact that you're hearing the eddies off the compressor (the engine had no slow RPM fan like most military jets), and from the back like the worlds largest hair dryer. At take off, it sent up a rooster tail of dust from the runway that went for a half mile. Sad that they retired the bird. Kelly Johnson was a super hero engineer.

RC Aircraft nerd here. This is very cool, but not at all uncommon (while this particular model is, making scale remote-control versions are not). Pulse-jet aircraft are some of the coolest things you can fly, but need a big field (for safety reasons).
