That's quite possibly the case .... and I did consider that prior to replying, but, also wanted to clarify things in case anyone was under the misapprehension that this modification was a re-enginning program .... as well as also wanting to posture FINE AIR's association with this particular HK3 modification too since I think they were the only operator whom employed this particular version .... although at least one of their HK3 modified DC-8-50F's did enter service with another operator (ATC COLOMBIA) for a brief period

We started this project early last year and as it progressed we ran into all sorts of difficulties with it .... all of which (thanks entirely to Paul's talents and efforts) we've been able to completely overcome and/or resolve per acceptable compromises
As I started out by saying at the commencement of this project .... when we begin making adjustments to established 3D models, and for which we already host "vast quantities of textures for", then we're limited, to some extent, in regard to what we can easily achieve .... simply because we can't risk applying edits to models that are likely to bump existing textures. We can't possibly replace every single DC-8 texture we've ever produced over the past 22 (now) years .... "OBVIOUSLY"
We took a much needed break from this particular project during the final quarter of last year .... but .... BOY OH BOY we needed that break !
As I've already implied .... this hasn't been a particularly easy project .... despite the fact the improvements applied have been of more than a pleasing nature despite some of the compromises we've needing to make along the way .... "UNAVOIDABLE"
We've just recently recommenced work on this project .... and are now well into the "NEW" DC-8-10, -20, -30, and -40 model edits .... the first of which are presented below for the DC-8-31, -32, and -33 SERIES.
These edits follow the same type of improvements applied to our already edited, and yet to be released, "NEW V6" DC-8-50, -61, -62, -63, -71, -72, and -73 models presented throughout past installments within this thread ....
DC-8-31 (PAX version)
DC-8-32 (PAX version)
DC-8-33 (PAX version)
DC-8-33F (converted freighter version)
DC-8-30 engine pylons .... fixed/improved over original 3D models ....
DC-8-30 engine Thrust Reverser's/Translation Rings/Silencers .... corrected detailing over original 3D models ....
DC-8-30 engine exhaust/tail pipe details .... corrected over original 3D models ....
DC-8-30 .... corrections and general improvements over original 3D models ....
DC-8-30F .... also subjected to the above-mentioned corrections/improvements ....
Expect more over coming days/weeks in relation to this "NEW V6 PROJECT" .... this time covering the balance of our DC-8 SHIP ONE 1958, DC-8-11/-12, -21/-21F, -41-/42/-43/and -43F models .... "as time permits please"

A dream would be if similar engine model updates could be done on the cv-990
As I mentioned within another thread recently. I do have something going on at the moment and in favor of the CV990's .... BUT AT THIS STAGE .... it doesn't extend to modeling (engine/pylon modifications can be "A MAJOR" and if undertaken for these models then there's no guarantee it won't bump the existing textures and which is something needing to be avoided at all costs). A separate presentation about this will be made later .... when I sense the time's right to do so
In the meantime .... let's try'n keep "this thread" focused upon "these DC-8's" .... please
Post by aerofoto - HJG Admin on Mar 22, 2022 0:37:12 GMT
Moving along now .... to the DC-8-41, -42, and -43, each of which are essentially similar to the P&W JT4A powered DC-8-31, -32, and -33 SERIES .... save for their (the -40 SERIES') RR CONWAY 509 fanjet engines.
The DC-8-40's were the first of the DC-8 flight line to be fanjet powered.
DC-8-41 (PAX version)
DC-8-42 (PAX version)
DC-8-43 (PAX version)
DC-8-43F (converted freighter version)
DC-8-40 engine pylons .... these details have been fixed/improved over those of the original 3D models ....
DC-8-40 engine Thrust Reverser's/Translation Rings/Silencers .... again corrected detailing over original that of the original models ....
DC-8-40 engine exhaust/tail pipe details .... also corrected over that of the original 3D models ....
A note concerning the DC-8-40's RR CONWAY 509 fanjet engines. Unlike is the case with RR CONWAY 508 fanjet engines fitted to B707-420's and which featured "considerably flared engine exhaust nozzles" (quite different from the B707-220/-320 type P&W JT4A exhausts) .... the exhaust ends of RR CONWAY 509 engines, on DC-8-40's, appeared "almost" identical to those of P&W JT4A series engines fitted to DC-8-20's/-30's. The DC-8-40 RR CONWAY's did feature a few extra nozzles/tubes, but, the additional number required is "INSIGNIFICANT" .... given the effort and mental anguish that'd be endured trying to incorporate these "TINY LITTLE" extra details, for our "NEW V6" DC-8-40 models, but which would barely be discernible anyway. Given the difficulties endured trying improve some this new detailing we now have, it's simply "NOT WORTH THE EFFORT"/additional frustration trying to do more .... and more-so given some of the original model source code is no longer available as I mentioned within the start of this presentation. What we now offer "IS (definitely) BETTER" .... and therefore "FINE" as it is. It's one of the fre and small compromises we've needed to make under prevailing circumstances
Be assured though in all other respects (panel/gauges, sounds, and FDE) these simulations are "GOOD"/authentic representations of DC-8-40 SERIES aircraft
DC-8-40 .... corrections and general improvements over original 3D models ....
DC-8-40F .... also subjected to the above-mentioned corrections/improvements ....
In regard to ARCA COLOMBIA (AEROVIAS COLOMBIANAS) DC-8-43 HK-1854. When acquired by this carrier (from ALITALIA), during 1976, it was never modified with a main-deck forward fuselage cargo door. It's possible the companies intention was to fly both parcel type freight or PAX (?). So far as we're aware (the father of HJG painter Camilo LUENGAS.R .... "captain Hugo LUENGAS" .... flew this particular aircraft for ARCA following the 1980 AEROCONDOR COLOMBIA collapse), HK-1854 retained in this particular configuration until its withdrawal from service and storage at BOG during the early to mid 1980's.
Expect more still over coming days/weeks in relation to this "NEW V6 PROJECT" .... covering the remaining DC-8 SHIP ONE 1958, DC-8-11/-12, -21/-21F models .... "as time once more permits of course"
"A REMINDER TO EVERYONE" .... none of these "NEW V6" models have yet been released, so, don't go rushing over to "DOWNLOADS" expecting to find something new. We'll announce when everything's ready/available .... but bear in mind please .... there's still "a lot" of work to be done

And now it's DC-8-20 time
Technically speaking that's both the PAX configured -21 and later -21F conversion/s .... "a few" of the latter type re-configurations were undertaken and actually flew into the 1980's.
Not working in any particular order among these simulations .... I just please myself as I go
The DC-8-20's were the first of the P&W JT4A turbojet powered DC-8 SERIES. The-20's, -30's, and -40's were all subjected to wing modifications (that were also retrofitted to the -10's) and which "progressively" improved the DC-8's performance .... given the under-performance of these aircraft in original DC-8-10 form. This's something that was slowly resolved .... although not entirely .... as the DC-8, with its 5* less wing sweep than the B707, was always slightly slower, but also, a bit more stable too in rough air conditions. The progressive performance improvements between these early versions is something we've incorporated into our FDE's (since 2015) and which results in each type being able to perform slightly faster/better than its preceding version .... provided these simulations are loaded and flown properly for starters of course The DC-8-20, -30, and -40 were each dimensionally identical, but, varied considerably in both their engine thrust and operating weights as these aircraft also became more range capable with each successive version .... something else we've also worked into our FDE's as well
DC-8-21 (PAX version)
DC-8-21F (converted freighter version)
No need to present wing, pylon, nacelle and T-Ring/Ejector/Silencer/Reverser details again .... as these features are all identical to the DC-8-30 and -40 versions already presented above.
DC-8-21 .... corrections and general improvements over original 3D models ....
DC-8-21F .... also subjected to the above-mentioned corrections/improvements ....
Still more to follow and covering both SHIP ONE 1959 and the DC-8-11/12 SERIES .... "again as time permits my doing so"

Have the engines the only things been updated on the dc8s? I can’t remember sorry
Engines (and their related features) are "just one of" any number of details we've "been able to" tidy up.
Other features have been "COMPLETELY REBUILT" .... along with new details added too .... among other features that "can" now be detailed which weren't possible to be detailed previously as well .... and whilst also (and most importantly) continuing to ensure the integrity of our "current texture mapping" for each model remains intact in order to avoid bumping every DC-8 texture we've ever released.
Suggest you "refresh your memory" by re-reading the entire thread again .... from first until the most current presentation/s as all of the "essential information" (that we at this time care to share) has been communicated
