  1. There is a difference between the two sets of AIRES nozzles, subtle though they are... The nozzle actuation rods/mechanism is slightly different as is the inner surface of the outer nozzle petals/feathers, although the differences are so minor as to be hardly noticeable, unless you're one of those rather sad, anal retentive 'rivet counter' types! -Daz

    Photo Phantom Phun!

    Yes, all USAF F-4s were dual control. -Daz P.S. once you get bitten by the 'Phantom bug', it doesn't let go...

    Italeri 2781 1/48 F-4J new release...

    Ok, thanks. -Daz
  4. Morning all, does anyone know if this new release from Italeri is a new tooling or just a re-box/re-issue? https://www.italeri.com/scheda.asp?idProdotto=2713

    Academy's 1/48 F-4B VF-111 kit markings

    If you have some doubt over whether a B is actually an N minus the ALQ-126 fairings and cable ducts, just look at the front cockpit canopy rails, if it's an N (with or without DECM fairings/cable ducts) it will have the VTAS kit fitted (also retrofitted to Js and all S models at rework), it's clearly visible in ground shots with the canopy open and usually shows as two triangular shaped protuberances just peeping above the canopy rails when the canopies are closed, the B's never had the VTAS kit, simples! -Daz

    Phantom FG1 auxiliary air doors

    There is often some confusion over the function of the Aux Air doors, the following is a summary of the info available from the USAF -1/USN NATOPS/RAF AP101 flight manuals. Put simply, the Aux Air on both J79 and Spey engined F-4s serve the same purpose, they provide additional cooling air at low speed and dump excess engine bay pressure when it exceeds engine bay pressure design limits, the main differences are, as I noted in my previous post, that the Spey engined FG.1/FGR.2 have the additional upper Aux Air doors (also called Ejector Doors) and are scheduled by the CADC, whereas J79 engined F-4s relied on the U/C up or down position. The excess pressure dump function was simply the pressure overcoming the hydraulic pressure of the actuator, once pressure is relieved, the actuator pulls the doors closed again, hope this helps clear things up a little... -Daz

    Phantom FG1 auxiliary air doors

    For those who may be interested... The Aux Air Doors on the FG.1/FGR.2 were always open below 210 KTS to provide additional air to the engines, above 210 KTS they would close but, would blip open when engine bay pressure reached +10 PSI above atmospheric, their scheduling was via the CADC. J79 engined F-4s were slightly different, firstly and most obviously, no upper aux air doors, just those on the belly, secondly, the aux air doors were controlled by gear selection, U/C down = doors open, U/C up = doors closed. Also, on J79 F-4s, when on the ground, if the engines were shut down or there was a sudden loss of electrical power the doors would literally slam shut, many ground crew have received serious injuries because of this and is why hydraulic ground locks were used. -Daz

    F-4C/D - Europe1 scheme

    Thanks, I'll know what to look for in future. -Dazza

    F-4C/D - Europe1 scheme

    Yes, Murph, that is indeed the picture I was thinking of, thanks for the clarification, weapons are not an area I am that up to speed on, among many other areas some would also argue! -Dazza

    F-4C/D - Europe1 scheme

    The AIM-7M was available to the F-4E/G/S, according to at least one publication, there is also a pic (official DoD) of an F-4G carrying AIM-7M but I can't find it at this late/early hour of the night/morning... -Dazza

    F-4C/D - Europe1 scheme

    What isn't? I clearly stated that TFS's carried out both attack and fighter taskings... -Dazza

    F-4C/D - Europe1 scheme

    As already answered, both, an easy way to tell is by squadron, FIS = Fighter Interceptor Squadron, these only undertook the Fighter/Interceptor air defence mission, TFS = Tactical Fighter Squadron, these squadrons undertook the tactical mission which comprised both fighter and attack taskings. -Dazza

    RAF Typhoon display aircraft Qu.

    It was mentioned (by someone who is on 29(R) sqn) that it has nothing to do with fuel needed to transit intergalactic mileage to faraway locations on our massive island, rather it was just easier not to have to drop (see what I did there?) the tank for every display and then add it again when the display jet was flown on normal sorties, that and the fact that given the Typhoon's SEP and agility, leaving the tank on would make practically no difference to the display routine anyway... -Dazza

    RAF Blue Phantoms

    I see your point re: establishment of 74 sqn using F-4Js but, that requirement only arose directly because of the need to deploy aircraft to the FI and it's associated impact on our NATO commitments, without that need the available FGR.2/FG.1 airframes was adequate (to what degree is open to debate of course) to maintain current squadron levels. Another point worth considering is that, as usual, government stupidity resulted in the FG.1/FGR.2 instead of an 'of the shelf' buy of an existing J79 powered model of the F-4. As far as the argument at the time for the RN/FAA's need for more power from the engines to operate from their smaller carrier/s, which the government decided could be solved by stuffing an afterburner on the civilian Spey engine (which was strewn with reliability problems before and after entry into service for many years!), GE had already said that the J79 could be made to deliver more power but, the UK gov had spoken! The resultant cost of the highly modified FG.1/FGR.2 (the most expensive new build version of the F-4) no doubt had an impact on the numbers bought, when quite a few more airframes could've been purchased of already existing models for the same or even less cost, thus enabling the spread of airframe hours/FI across a larger, easier to support fleet, hindsight though is a wonderful thing... -Dazza
