  1. Gadroc, I saw you mention the Leonardo board. Could this solution be implemented on other boards like the Mega or Due?
  2. Nellis plays host to many shooting ranges used for air to ground weapons practice.
  3. Well, it's good to hear that I was right on time. :)
  4. I figured I would need dedicated code on the Arduino. Is there an example somewhere that I can try? I'm not a very accomplished coder, so a guide would be useful.
  5. Hello, everyone. I'm have a question about getting Helios to talk to an Arduino via EOS. In Helios, I add a serial interface and select the COM port that the Arduino is on. Helios says it's scanning the port, and I see the Rx light on the board blinking. When it's done, nothing shows up in Helios. What am I missing?
  6. I'll throw in another vote for digikey. I like the part sorting/filter system they use.
  7. Froogle with the WarHawks fairly regularly livestreams many sims, including the Ka-50. twitch.tv/frooglepete edit: Forgot to mention that he announces streams on his Facebook page:https://www.facebook.com/Frooglesim?fref=ts
  8. I will add another voice to the praise for both of Mike's books. Even if it isn't in the format you want, I would say buy one anyway. It will probably make him feel better about writing his third book!
  9. In theory, none of them fell to the ground. The SA-2 had the rocket motor to get to altitude, but the flight controls were not effective up there, so they couldn't guide. What the Russians did was "shotgun" the missiles by shooting a bunch of them in the general area of the U-2 and detonate them at the same time. In the book I mentioned, Ben writes that they determined that the shock wave knocked the vertical tail off the plane and caused it to depart controlled flight. It also knocked down a Russian aircraft attempting an intercept. Something else mentioned in that book is that Powers' flight used the same route as the flight a week before, so the Russians knew exactly where to shoot.
  10. There's a book written by Ben Rich (the man in charge of the Skunk Works after Kelly Johnson) that goes into more detail about the U-2 and D-21 incidents. It's a very good and entertaining read. http://www.amazon.com/Skunk-Works-Personal-Memoir-Lockheed/dp/0316743003/ref=sr_1_1?s=books&ie=UTF8&qid=1324755334&sr=1-1
  11. With ~14 SA-2!:surprise: The launch must have been something to see.
  12. All sorts of steer! :megalol:
  13. :megalol: Merry Christmas everyone! :santa::yay:
  14. Damn, I have $300 just sitting on my desk? :surprise:
  15. Here's the actual True Type font file. Have Fun!:thumbup: MS33558FONT.ZIP
  16. I'm nowhere near a RL A-10 pilot, but those wings aren't really going to move much. You might notice flex if you crank into a really hard turn, or drop something really big. Also, http://en.wikipedia.org/wiki/Inner_ear http://en.wikipedia.org/wiki/Vestibular_system
  17. But it isn't the standard light gray either. It looks almost like primer.
  18. Lolz at the clip.:D My avatar is a concept airplane I sketched then made in Solidworks. Consider this at the napkin -sketch stage, and on hold while the A-10 simpit gets built.
  19. Low frame rate, anyone?:D
  20. Check out what these guys are doing: http://www.youtube.com/user/TheDmel
  21. Doesn't that lead to a heat exchanger for the cockpit air?
  22. I just Googled this and this thread was the second result.:D
  23. Cool stuff. Seeing all of those B-17s running at the same time must have been impressive.:joystick:
  24. The stall speed only goes down in 1G flight. Remember that a stall has nothing to do with speed and everything to do with AoA. In that regard, slats allow flight at a higher AoA. That fun fact also applies to the A-4 Skyhawk. From wikipedia: "The leading edge slats were designed to drop automatically at the appropriate speed by gravity and air pressure, saving weight and space by omitting actuation motors and switches." Also, according to the A-10 manual, if hydraulic pressure is lost, the slats will extend and stay there. Why thank you.:)
  25. Okay, I'll try my hand at a visual explanation. The first image is at a low angle of attack. The flow around the wing is nice and smooth, and thus stays "attached" to the wing over the vast majority of its travel distance. In the second line, the wing is at a high angle of attack, but without slats. The air by itself doesn't have enough energy to "make the turn" around the leading edge of the wing. The flow separates and becomes turbulent. This turbulence propagates towards the engines, and they throw a fit. In the last line, slats are added, which help turn the flow onto the upper surface of the wing. The flow stays attached for longer, and the engine is happy. So, in a word, slats allow a given wing to fly at a higher angle of attack without flow separation, which is what constitutes a stall.
