Hope this helps:

After much wind-tunnel testing, it was found that the new McDonnell fighter would encounter severe stability problems at high speeds and would as a result probably be limited to speeds below Mach 2. In order to correct these problems, several important changes had to made. One of these was the application of 23 degrees of anhedral to the all-flying tailplane, which became known as a *stabilator*. This gave the necessary degree of stability but still left the tailplane free of the jet exhaust.

OK, fair enough...but what does a stabilator do? ::)

Erez:  What do the PW engines look like?  The F-4K was the only one to use a different engine and it shows when you see it next to other versions. ;)

Whitey. Read the description.  ;)

Stabilator is another name for all-flying tailplane. These work in the pitch axis only, much like elevators. They should be much easier to animate than elevons.

So, they're just basically pitched elevators?  Thanks for sorting that out. ;)

Nic and easy to animate. ;)

Just make sure you get the axis correct & they move in the right direction. I've seen too many people get it wrong.

Whitey, the PW1120 is a sub model of the F-100 :)
you can see it at the link I gave to Hagar before ;)
I also try to make a good PW1120 engine for my Lavi. I'm still working on it. It's OK until now, and maybe I could send it to you after I'll done. But please take your own try, since I bet you can do a better one than me;)

Well I just wrote to the Pratt&Whitney site in request of info and pics on the PW1120. they don't even mentioned it at the F100 engine's page..... weird....

Actually I can't model to save myself.  All I've done on the Phantom is rename parts and animate it... ::)...I don't even know how to make the engine nozzles open wider as more thrust is added... :-[...my real speciality is textures. :)

Anyway, I guess the PW1120 is afterburning?  Also, does anyone know how the Phantoms afterburners were controlled?  Was it with throttle postion or by a separate switch?  Thanks...

Getting the nozzle petals to expand with thrust is more tedious than it is difficult.  First of all, the "nozzles" aren't - they're throttle sticks.  Each petal is key-frame animated as a throttle stick, so that at low throttle settings, they don't move, but at afterburner throttle settings, they move.

Where you get the tedious part is in carefully crafting the overlapping petals and getting the coordinated motions "just right".  This is where you'll probably spend more time calculating the "math/geometry" of the positions to get them just right rather than visually moving the parts "to fit".

No kidding....... I'm also pretty good with textures......
Designing is hard for me, since I'm doing a model from scratch..... but I'm doing my best and I know there are people here I can ask questions and they will answer and help me.... ;)
Well I guess it gonna take me some "quality time" with that engine.... oh well.......... :(

Elevons are a rudder and elevator combined into one... while not much of an expert on military aircraft (ok, no clue)... They should be defined as a Stabilator.  It is clearly defined within the screenshot that the aircraft has ailerons.

elevons are elevator/ailerons - such as are found in tailless ) delta-winged aircraft...  .. and I believe in some of the more modern aircraft (I *think* the Blackjack) the horizontal tailplanes (all-flying/stabilators) also have a differential movement that complements the ailerons...


ruddervators are the rudder/elevator comination, as are found on V-tailed aircraft (Beechcraft Bonanzas, for example)

I confirmed this point yesterday by asking a friend closely involved with the F-4 & warbirds in general. He confirmed that no version of the F-4 Phantom is fitted with elevons (combined elevator/ailerons). It has a conventional "all-flying" or "all-moving" tailplane, sometimes referred to as a stabilator (horizontal stabilizer/elevator), commonly used on jet airliners.

All versions of the F-4 use a system of ailerons + spoilers for lateral (roll) control. The ailerons have no upward movement & operate between neutral & down. Both ailerons droop when the aircraft is parked. The ailerons were also used as flaperons on the F-4J to improve landing characteristics for carrier ops. "The F-4J introduced 16.5-degree drooped ailerons, which is a fancy way of saying that with gear and flaps down, a downward deflection of 16.5 degrees became the "neutral" aileron deflection."

Now that we know all that, do you have any idea when it will be released? I mean, the only hard thing that is left to be done is texture mapping and files :)
Do you need any help? should I find you something?
