Very nice indeed. Really like that 'camo' scheme. What was the operation history of this beauty? Cheers mate  David

Col what other insert codes are those??? 151 0/1 - 152 0/1 are there now...these are the same codes i only see in the last Horten 3dzs??? Those are the action codes which switch things on / off. To make the Horten gear fold properly, I need at add Insert codes, so one gear folds back, one left, and one right. These codes create the animation of the gear folding Codes have to be added to the points, in the last column, which is normally 0 [zero], Normals last column, which is normally 0 [zero]. When the Insert codes are active, the points and Normals for each Element, are linked by the 0 [Zero] changed to 1,2,3, and so on. In the 3dz Header you will see the number of Parts increased, and extra lines added to the Inserts. [HEADER] INI=183 TEXTURE=PP51DTEX.PCX PARTS=1POINTS=190 ELEMENTS=225 ; place here the preview bitmap file's name. Useful to 3dz library PREVIEW= [END] [INSERT] ;I000=_cod _num _y _z _xThe folding elements normally are offset around the zero center of the model.

...in a word, dismal! for starters though do a search for Operation Steinbock. on the other no he177 was known to have been shot down by an interceptor because the crews initiated an excellerated dive before clearing the english channel to target, lost more ac just on takeoffs!!!
thanks Col, didn't know what that line was fully for other than those xyz coordinates related to shifting prop positions.

Some were used in anti shipping,some where used in the "mini blitz" late in the war..To make it realistic you have to have the engines catch fire for no apparent reason.Well being a siamesed engine (2x Db605,s coupled together) oil and fuel would leak onto hot exhausts.Also like most German bombers they were setup as a "dive bomber".I,m just thinking of a way on how the FritzX bombs would work..Coders??

Hi Guys,
Superb model - I agree with Mike about the colours as well. My old Airfix kit is two green uppers, light blue grey unders and sides with an RLM 02 mottle, and 3 Hs 293 missiles for anti shipping. I believe it is meant to represent an aircraft of II/KG40 operating from Bordeaux-Merignac alongside their Fw 200 Condors and later Ju 290. For Operation Steinbock ( the little Blitz) the undersides and sides were painted black.
The curious thing about the Greif ( to me at least) is the way it resembles the Avro Manchester. Both were designed with the idea of using 2 very powerful engines, in both cases coupled units, the Greif used DB 610's and the Manchester used the RR Vulture. The idea was that with only 2 engines and nacelles and a shorter wing there would be considerable reductions in both drag and weight. Unfortunately both engines were unreliable, failed to produce the expected power and had a habit of bursting into flames. Roy Chadwick of Avro extended the wing and fitted 4 lower powered Merlins to produce the Lancaster, and Heinkel were looking at doing the same but the German "powers that be" obstructed them until it was far too late.
The He 274 with 4 BD 603 A-2 was designed early enough but production was transferred to Societe Anonyme des Usines Farman in France and progress was slow and the Germans were forced to evacuate the plant after D Day, though the French continued work on the prototype which eventually flew in December 1945. Speed was 267mph at sae level rising to an impressive 360 mph at 36090 ft, range between 1770 miles and 2640 miles depending on speed, altitude and load, and a max bombload of 8820lb internally. Except for the bombload, pretty impressive. A "simpler" 4 engined version with a shorter wingspan, the 277 was proposed as early as 1940 but Goering did not like the idea and so it was 1943 before the first prototype flew, and the whole programme was scrapped in 1944 to make way for the " emergency fighter programme". Performance similar to the 274, bit slower but much greater range. Both 274 and 277 had twin tailfins on a basically similar fuselage.
The final odd parallel between the Manchester and the Greif is that there was actually nothing basically wrong with the coupled engines. RR were very busy with Merlin production at the time they launched the Vulture, so could not spend much time in developing it, but by 1943 they had worked out most if not all of he bugs and it was working well. Similarly, after exhaustive study at the Luftwaffe test centre at Rechlin again in 1943, no less that 56 possible causes of fire were found and eliminated and the modified DB 610 performed flawlessly on extended tests but by then it was too late. More info and plans available if anybody is that interested.
Sorry for another long "lecture" but I though some of you might find details of these little known aircraft of interest.
Cheers
Pete

itm! a quick B24 wing stickon test for that long range He277 bomber version using the v1v1 slot...  works pretty good there except i don't know why the resolution changed because thats as close as i could get unless am intercepting.

Hi Flyright, Actually that works very well - span of the real thing would be about 20' greater and the wing and tail surfaces tapered a bit more but it gives a good idea of what it would have looked like, so if somebody had the time and inclination it should be possible. For those unfamiliar with the aircraft in question:- This is the He 274 - much increased wingspan - built in France (slowly and sabotaged as like as not. One flew after the war.  This is the simpler He 277, two flew before the programme was cancelled.  Pete
