    The Tomcat couldn't do that if I recall, at least not the early ones with six Phoenix(es?) due to carrier weight landing limits.

    I know the missiles are getting all the attention, but thats not a Hornet colour scheme one sees often is it?

    That's Vandy-1, it is a bird that flies pretty exclusively out of CHina Lake for flight test purposes.  The coolest flight test bird flying.

  2. I am looking to rehome the following Valkyries from my collection, I need to downsize for an upcoming move.  All prices are plus shipping; Continental US is preferred.

    Unless otherwise noted (the VF-27) all are complete in excellent condition with no damage and were kept in a smoke and pet free home.

    Additional pictures available upon request.  All units are also listed on FB Marketplace.  Can also meet up in southern AZ.

    Bandai VF-27 (1st Edition)  $100
    Nose has broken off but is still included, missing manuals.

    Oh wow, that is a funky-looking design, not at all what I expected. I thought it would basically just make the bottom exhaust look like the top so you'd have this like three-pronged tail end sticking out the back with the exhaust nozzles seeming to be set into the airframe. 

    So the one of the left is the Production F-23A concept.  It would not have had thrust vectoring, focusing more on stealth and speed (YF-23-2 was so slick and fast nothing could catch it, not even the chase F-15).  A thrust vectoring F-23B(?) was discussed at NG but never made it far because they lost the ATF Competition.  The NATF concept is on the right, and had a couple of iterations, that is the first one, with canards (super sexy) and thrust vectoring.  The later iterations ditched the canards but were externally pretty similar.

    Thrust Vectoring was never a requirement for the ATF Competition.  But, LM put a lot of research and development into it so incorporated that into the (Y)F-22 because they wanted to give it more agility.  ANd it added an extra wow factor at the competition.

    I remember hearing in a random video or magazine article or something that in response to a late ATF requirement, McDonnell drafted up designs for a thrust vectoring YF-23. Anyone know if this is the case and/or if it ever made it to any form of visual representation? Getting a model or a Ace Combat mod based on even prototype artwork would be cool to see.

    In short, sort of.  The original ATF requirement called for thrust reversers and that was pulled late on, so the YF-22 never had them, but the first YF-23 did.  The second one did not, and because of the lost weight could outrun pretty much everything else.  A thrust vectoring F-23A and NATF were drawn up and proposed during and after the competition.
    Why was the YF-23 not turned into a Naval fighter like the YF-17 was turned  into the Hornet? - Quora

    Sorry for the delay in this, but this isn't the news I was hoping to share. In designing this, there was a part that had an issue that was unclearable. As I tried rolling it back to fix it, it lead to there being a roll back of everything to the very beginning. At this point, I had no choice but to scrap the work done on this. I will need to start from scratch. It's not the worst thing, as there were issues I wanted to correct, but it was a lot of work. At least on the bright side, I have a better know how of some of the complex parts, and being that I now have a plan of attack on this that will give me a better layout, I should be able to make this better, and incorporate some other features I wasn't planning with the first version.

    I guess the things that suck can be a point to fix things, as normally should be the case. As I am getting the new 3D printer that can print production and working type materials, I plan to incorporate these into the tests as I move forward, so I can test not only fitting, but materials under certain stresses that the figure will have. I have 3 materials that can basically make this a workable toy, and dyes for the resin that can give them the color it needs to hopefully require little to no paint for this.

    No worries, these things happen.  What was the issue that couldn't be cleared?  If you don't mind me asking.

  6. Well, the redesign of the YF/VF-19 and YF-21/VF-22 have real-world examples.  The YF-22, YF-23, X-32, and X-35 were technology demonstrators and were never meant to be representative of the final production aircraft.  The YF-22 is actually a good example since we did lose one during testing due to Pilot Induced Oscillation (PIO), which is a major concern in any fly-by-wire aircraft. I even worked on the Flight Test Program where the goal was to limit PIO as much as possible.  

    Now, we do not know why the YF-19 prototypes crashed; it could have been for any number of reasons.  But consider this: the YF-19 had one the most complicated transformations to date at the time (In the real world, yes, the SV-51, VF-9, and other advanced Valkyrie designs had some pretty origami transformations).  So, the crashes could very well have been a result of that locking up or the pilots initiating them at too low an altitude or other PIO-like issues.  The fact two pilots were killed leads me to believe that they were both aboard the first prototype when it was destroyed; perhaps one was acting as the onboard Flight Test Engineer (FTE) in the back seat.  The other two point to an issue with the flight control computer not being properly attuned, which tracks with what we know about the Chief Engineer wanting to do anything and everything to prove his design was the absolute best.

    Once selected, the -19 would have undergone an extensive redesign for the production version, eventually leading to the VF-19F/S/P/Kai.  However, like RQ-4A Globalhawk, there was an immediate need for the VF-19A to go into Low Rate Initial Production (LRIP) to fill a gap in the UN Spacy Space Forces.  These would likely have been derated in comparison to the YF-19 to make it more manageable for the average pilot, likely by adjusting the engine output, limiters, transformation mechanism, cockpit, and Tactical Operational Profile.  

    Maybe the Master File has a better explanation for the redesign and why the YF-19 flight test program faced so many issues, but that has always been how I looked at it.
