  1. Brake chutes and reversers are designed differently, yes, but that doesn't mean that a chute can't act as a crappy reverser. When your clay sticks to the wall, that's what's called a totally inelastic collision. You spend some of the kinetic energy the clay had to reshape it, etc. Molecules, when they hit the chute, however, basically collide elastically. That's why this situation is like case 3 in my wagon example and not case 2. Also, in your drawn chute, you can't just have an eternal density buildup inside that box. If gas escapes forwards (the way your nose is pointing) (we need to assume that the chute doesn't leak or break), you have that momentum we are looking for.
  2. There's something funky with wind interaction, yeah. There's another bug report about the plane not responding correctly to crosswind.
  3. Not to argue from authority, but I do have a degree in physics, so at least you know I'm not talking 100% out of my ass. The thing to realize is that the exhaust gas doesn't stop the moment it reaches the chute, but recoils from it. That's also the reason blowing a fan into a sail actually does work, only rather poorly. I'd also ask you to consider a thrust reverser and ask yourself what the difference is (conceptually there are none). Imagine this scenario: You're standing on a wagon, holding a ball. You throw the ball forwards, off the wagon, and momentum conservation in the system means you roll backwards. Now, imagine there's a wall mounted on top of the wagon, in front of you. You throw the ball against the wall, the ball stops dead and drops to the floor of the wagon. You'll impart momentum on the ball, and the ball will put it back into the wagon, and you'll have no speed after the ball has stopped. Ok, now the crux: You throw the ball against the wall, and it bounces off the wall and lands slightly behind the wall. Clearly, compared to the previous case, there will result a forward net translation. It's obviously much less efficient as a mode of propulsion than just throwing the ball backwards to start with (analogous to mounting the jet engine backwards in our case), but it does work.
  4. Awesome. Looks like you had a similarly crisp, clear and beautiful (and warm!) autumn day as I did over here.
  5. It should reverse. EDIT: I'll expand. Assuming an ideal system (chute doesn't break or leak, etc), and that all the hot gasses from the engine hit the chute, then applying throttle will result in a net backwards force. It's basically like a (crappy) thrust reverser.
  6. The Sabre is such a stable aircraft that you generally need pretty much zero rudder to stay coordinated.
  7. The A-10 might be a bad comparison since it has two barn doors for rudders. The point still stands without that comparison though.
  8. Certainly: I expect, when I apply considerable rudder and keep wings level with ailerons, that my course should perceptibly deviate. It doesn't. Because I can barely even notice it when I apply FULL rudder. I don't have data, but in the sim currently, in my submission, rudder turns are completely impossible for any practical purpose. You can't line up approaches, etc. Again, I don't have any charts (couldn't find any) regarding what the performance should be like, so take this with a pinch or two of salt, but surely this can't be right. Further, considering that the F-15 would seem to have the same issue, it becomes more likely to me that BST's FM is a bit off in this area.
  9. I think it depends on which country you play as.
  10. The version you download and install from the purchase page is always the latest one.
  11. That layer of scratches is fugging awesome. Looks just like how old printed photos used to get when you had a bunch of them in a pile.
  12. Nothing tabulated has ever been false. Trust me, I'm a scientist.
  13. Sorry, but I don't care how well it flies, how cheap it is to make or what it can do. It's unbearably ugly. Scrap them all, please. If it could speak, it'd say KILL ME.
  14. I'd guess hardware problem. Almost certainly not game-related. I'd try reinstalling the drivers.
  15. Looks great! Good work, buddy.
  16. I mapped it to the NWS button on my Warthog, works great.
  17. Hold down NWS key! (S, I think?)
  18. You forgot the only relevant part of the url.
  19. Right. The early versions of the aircraft had aileron trim, but they removed it to save weight when they changed the shock cone movement axis.
  20. Nah man, you've got it all wrong. The 21Bis (and certain export versions IIRC) had a side-moving nosecone. It's to compensate for asymmetric load once a missile has been fired from only one wing.
  21. Holy crap. Want.
  22. The BEEPBEEPBEEPBEEEP from the MWS is even better. Found in dcs world/sounds/effects/aircrafts/cockpits/rwr/launchwarningus.wav
