Hello friends::)

See this video, you can see the slats moviment, are like in the F-16 or 18. No like in the AsiaSRC model or Miniflyer´s post drawings. Which is the version in the video ??? F-4N ???

http://www.youtube.com/watch?v=zdXGNhKZ1LQ

See too in the video the moviment of spoilers, airbrakes and all surfaces. GREAT !!!

Regards from Spain.

Carlos.

Hi Mark::)

If I want to make the naval version I think that I need to make leading edge like the video not droped slats, no?

Regards.;)

Carlos.

Hey Carlos, I am not very familiar with the Navy versions. I believe the J model had fixed leading edge slats on the stabilator but did not have slats on the wing. Depending on what picture you see, the inboard wing leading edge slat or flap on the J model is fixed and on some other pictures it is extended so maybe that is a B model or N Not sure. Sorry, my partical experience is with AF version. I have read somewhere that very early E models did not have slatted wings and where modified, someone out there can clarify. If so the RC jet above could in reality could be very accurate with leading edge flaps?

Just a few without, gotto to be black/white era.
5000 out there, just hard to track each!!:)

Hy Mark,

you are right, the early E's did have hard-wings, the slats were incorporated after severe losses due to stall buffet and spin onset in close combat maneuvering (high alpha). I believe many of the early productions were also retrofitted with those slats in an upgrade program.
There are 2 combination of leading edge devices used on F-4s as far as i could find out. Apart from "none at all" that is....
-"Leading edge flaps" on inboard and outboard wing, mostly used on recce and navy versions (short-noses)
-"extending inboard slat and pivoting outboard slats" on most air force variants (long noses)

The inboard extendings are very very difficult to get right, very small deviations (around 1/10th of a millimeter!!!) in the rod length cause very very wrong movements. We have chosen to go CNC-machined to 3/100th of a mm) on those, otherwise there is simply too little guarantee for scale function.
The pivoting outboards are fairly easy to do....

Best regards
Hank

PS: The RF-4E was flown with the german air force :-)

Hey Hank! Very cool what you are doing, looking forward to seeing the final product! I believe Turkey is still flying RF-4E's as well...

Another maybe unknown tid bit of useless info, RF-4C's at one were nuke capable... a little box with a timer and a lite with a stencil below the lite saying pull up! Must have been for the bomb toss half loop immelman manuver. Talk about in the hit or miss!

Hello::)

I put two drawings of the F-4E and another two of the S versions with the same leading edge slat.

Cool! That F-4S scheme is RC model worthy. Folding outer wings would be a unique touch for a detail to add to yours.

Something I have never seen on any RC Phantom is the use of the spoilers. Phantom Ailerons dont operate in the traditional sense as they do not deflect upward in a turn (only a couple of degrees) the spoiler operates opposite of the aileron.
There was a Century Jets Phantom somewhere that used the scale wing surfaces (aileron/spoiler), but I don't remember who built it.

The F4J did have a slotted stab. as did some other variants to improve control at lower approach speeds. Here is my rendition of it on my BVM F4, a J model aboard USS America.

Made of moulded layers of 1/64th ply wood. Zero affect but looks good though !

Never did get around to incorporating the LEDs, too hard box !

Gary Baker,

That plane with the scale wing with the spoilers , I saw Lewis Patton fly it at Superman Jet rally, and it was a Century Jet F4, but it was a ducted fan.

It was also a very simple setup in such that the spoilers were activated by servos directly below the spoilers. The servo horn rotated up to raise the spoilers and they were spring loaded for the down position.

Hello::)

In the video you can see the moviment of the spoilers in combination with the ailerons. The Ailerons move only down and a little up mixed with the spoilers.

And what happen with the airbrake ??? anybody will try it ???

Regards.

Hi Albert

Nice Aircraft ! Is that your entry for the 2009 WJM ?
