    What will Hasegawa do next?

    Since "Movie Edition" is on the box of the Q-Rau what are the odd of Hasegawa doing a TV Edition?  I was surprised how quickly they released 4 different versions of the Regult although each of those were just additional sprues.  How significant of a difference is there between the Movie and TV versions of the Q-Rau?

    Hikuro,

    Any news on getting the drive fixed? I would be willing to bet you could get a used Seagate drive off ebay of the exact same model.

    Last year I bought the Western Digital passport solid state 1TB drive off Amazon.

    No complaints yet other than my PC isn't USB 3.0 so transfer speeds are limited to 2.0

    Hopefully this isn't a sour topic, but I just watched your dub Hikuro (via youtube), and I thought it was brilliant. I have a question that probably exposes the noob that I am, but at the beginning of the film when the Zentradi are talking there are what appears to be Japanese subtitles under your subtitles. Was the Zentradi dialog in Japanese or another language which required the subtitles?

    Here is my home theater room.

    http://www.avsforum.com/avs-vb/showpost.php?p=9796602&postcount=2222

    Setup:

    Ascend Acoustics CBM170SE Left and Right Fronts with CMT340SE Center and HTM200's for the rears.

    SVS PB10-NSD sub

    Onkyo SR804 Receiver

    Oppo971 DVD

    Xbox360 + add on HD-DVD drive

    Not shown in picture is a Sony BDP S570 Blu-Ray player

    Mitsubishi HC3000 projector (home made Monkeyman mount)

    Screen is 102" (16x9) also DIY with Silverfire super lite screen paint from the screen DIY forum.

    Back in 2007 when I bought the projector it was around $2k now you can get it used for $275 :( Buying a used projector I could put this system together for around $3k now. By all means do NOT buy HDMI cables at a chain store like Best Buy, Fry's, Circuit City, etc. Go to monoprice.com and pay 1/10 of what the chains are charging. I've got a 30' HDMI running up the wall behind the screen over the ceiling to the projector and it's perfect. And that's a "crappy" first gen HDMI cable. I made the screen from blackout cloth and a screen paint mix from the avsforum. I also made the couch riser, speaker stands, and component stand. If I were to do it again I would make a vertical component stand and put it in the back of the room and not directly under the screen. All the LEDs from the various components are annoying to look at while watching a movie.

    Xbox on anything smaller than a 100+ inch screen is now unplayable for me. It's also really nice when 4 people are playing because each person still gets a pretty nice size screen. My kids love it (spoiled little farts) "back when I was a kid and we played pong and loved it!"

    Halo Reach co-op campaign on Legendary is LEGEN.. wait for it... DARY! There are some lag issues but I guess it depends on the regions of the players involved. Also is it just me or is the weapons/grenade spam even worse than previous Halo titles when playing on harder difficulties?

    Love the new needle rifle too.

    I'm not that far into the campaign but what is weapons/grenade spam?

    Steve68, watch the video that anime52k8 posted, the VF-1 thrust vectoring has a range of movement far greater than what the F-22 shows in the video you posted.

    Watch the video I posted. The F-22 nozzle movement is not far off what is shown in the PS1 DYRL video. Also note that the horizontal stabilizers in the video I posted are moving in addition to the nozzle. So the plane would be pitching less if the stabilizers had not moved. What that means is that for a fighter to use thrust vectoring alone to achieve large pitch changes is going to require the nozzles move huge amounts. If the nozzles deflected that much then the plane is going to slow down very quickly as you are trading straight line thrust for a vertical component. It's a pretty simple trig problem to figure out that your thrust would go down by 30% if the nozzle pitched to 45 degrees. At 60 degrees the horizontal component of thrust would be 50%. I think the lesson to be learned is that thrust vectoring works well with horizontal stabilizers to 'augment' pitch control, but as the sole means of pitch control it is a poor choice.

    Steve, the F-16 can't fly if what you're saying is true. Nor can the F-22, F-35, or really any fighter plane since 1980-something. The computer controls the plane's control surfaces, making very minute changes to react to the slightest movements off-level. The adjustments are minute, so unless you were on the plane, looking at them, the paddles wouldn't appear to move. Also, Macross animated on a 1980s budget. That's just not possible to do that at that time. That said, the VF-1 is explicitly stated by all sources (Yes, even Robotech) to have both 2D thrust vectoring and Fly-By-Light controls.

    Fly-by-wire and Fly-by-light are used a lot lately, not only because the systems weigh less, but because they can provide changes to control surface area by the tiniest iota, according to computer commands, meaning the flight data actually goes to good use, keeping an unflyable plane in the air.

    Besides, the VF-1 likely has most of its weight towards the back, meaning it can be more easily thrust-stabilized, if I'm not mistaken.

    I'm not sure if this was directed at me, but what I'm saying is true. The center of lift of the wing is NOT at the center of gravity. That's a fact. Because of this the aircraft needs to have something to counter act the pitching moment that is created by the difference between the two points. This is why non flying wing aircraft have horizontal stabilizers. The stabilizer in level flight provides a downward force on the tail of the aircraft. Without the the tail the plane would pitch down and be unable to fly. The amount of travel that an aerosurface moves on modern fighters is directly proportional to the aircraft speed. You should watch some video of the planes taking off or landing. You will see surface movement that you could measure in feet! At higher speeds the aerosurfaces movement is less dramatic. Another point to remember is that tail surfaces by their shear size provide a lot of lift (remember all modern fighters have full flying stabs) so a little bit of movement provides a lot of force as the speed increases. Thrust vectoring is different. You need a lot of movement to get the same amount of pitch force. Don't believe me. Watch this video at about the 3 minute mark you can see how much nozzle deflection is required to get the nose to pitch up.

    I think it would be highly unlikely that it (the VF-1) could fly. The main reason being poor pitch control. Since the center of lift and center of gravity aren't at the same point then there will be a tendency for the plane to either pitch up or down (depending on where those two points are relative to one another). Now the center of lift changes as the wings sweep as well as when the plane goes super sonic. Yes I know that it could use the engine exhaust for thrust vectoring to control pitch, but the question becomes "did it?" I can't recall seeing a single scene with a VF-1 in fighter mode where there was any movement by the nozzles indicating that thrust vectoring was being used. I think if it were modified just slightly it would stand a much better chance of actually flying without a need for thrust vectoring. Just angle the tails out away from each other ala the YF-23.
