I understand the Stuka had dive angles etched in or painted on the Perspex on the pilots side window to give him a quick visual cue of (surprise, surprise) the angle of the planes dive. Does anyone know the answers to the following pls:

1) What were the dive angles? (I think I remember reading 60, 80 and 85 degrees);

2) Where exactly were the lines placed i.e. which windows and left of right side? and what were there colour;

3) Did all models of the Stuka carry the marking on the window? (this is particularly relevant because the variant we are working on is the G-2 'tank-buster').

Any info is much appreciated.

For anyone interested in an update on the cockpit, the front panel and cockpit wall are complete, as is the rear cockpit. Tonight I will do the window reflection textures (limited to a few windows to remain framerate friendly) and begin work on the instrument textures (many of these are unique to the Stuka and have to be blended into the panel background).

According to 'Battle of Britian' (Bickers) the stuka enters the dive at 15000ft and dives at 80 deg 350 kts. The pull-out height was preset at about 4000ft with automatic bomb release soon after.

30-90 degrees is 10 degree increments, on the pilots starboard side window. (Foremost window on the starboard side of the opening part of the canopy)

THe JU87 A had a large trousered landing gear,and full equipment for dive bombing , including a HEAVY BOMB CRUTCH the swung the missile well clear of the fusalage before release.

The spatted Ju 87b was the first aircraft in production with the Jumo211 engine almost twice as powerfull as the Jumo210 of the Ju87.
and it had an automatic device (autopilot) to ensure proper pullout from a steep dive, AS WELL AS RED LINES at 60, 75 and 80 degrees painted on the pilots side window,, Experience in SPain had shown the pilots could blackout and lose control in the pullout. Later a whole formation of ju 87b's in Spain was late pulling out over misty ground and MANY hit the ground.

Found this page :
http://www.kotfsc.com/aircraft/ju-87.htm

to quote :

The Ju 87D-5 had the outer wing panels extended to give a span of 49 ft 2 1/2 in (15.00 m), the increase being necessary to cope with the heavier loads that were being carried. Dive brakes were omitted as the variant was intended only for ground-attack.

Ju 87G

Dive bombing was not possible with the additional weight of the guns, so the dive brakes were also deleted.

Your variant wouldn't need the marks...

Any chance of a B variant, the spit 1B and hurricane need something to mash!?

The tank busting version (Ju87G-1, Ju87G-2...) was a strafing variant that did not do much (if any) diving. It was used mostly over the Eastern front as well. If you need any info (weights, dimensions, ammo, weapons, flight performance, cockpits, side views, views on how things looked and worked on just about any part of the aircraft...) I probably have it. The earlest info I can provide you with is the Ju87V1 prototype and the latest info is the Ju187 project. The dive brakes were removed so I dont think the window angle markings were there.

P.S. The Ju87G variants with the 37mm BK 3.7 (Flak 18) anti-tank weapons are my most favorite of the Ju87 series so Im glad you are doing this model. I hope one day some B variants are made for the Battle of Britain side of SDOE but any Ju87 is exciting to me!

Ju87D and above Operational/Proposed Variants:

Ju87D-1:
The basic "Dora", and first of the most widely produced series. First operational on the Eastern Front in Febuary 1942. Like all subsequent Ju87D variants, often flown without main wheel fairings due to the soft conditions of landing grounds in the East. Could be adapted for close-support tasks, with provisions for underwing gun packs. Retroactively fitted with explosive bolts to jettison the main undercarrage.

Ju87D-1/trop:
Tropicalized variant with engine air intake dust filters, protected lubrication system and desert survival equipment. First operational over Bir Hakeim in May 1942.

Ju87D-2:
Strengthened rear fuselage and combined tailwheel/hook for towing the Go 242 cargo glider. Intended for use in North Africa and the Mediterranean area.

Ju87D-3:
First specialized ground-attack variant. Basic "Dora" air-frame with added armour protection for the crew, engine and radiators. Retained wing dive brakes, but deleted propeller driven dive sirens in undercarrage fairings. Late production series had completely mass-balanced ailerons. In production from late 1942; operational principally on the Eastern Front. Frequently carried disintegrating plywood containers with 92 4.4lb SD 2 anti-personnel bombs on underwing racks. Total production amounted to 1,559 Ju87D-3s completed at the Lemwerder (559) and Tempelhof (960) plants.

Ju87D-4:
Intended as a torpedo-bomber to carry one 1,687 lb LT F5b or similar torpedo. Evolved to a June 1941 requirement, only a small number of Ju87D-1a and D-3s were so converted. None used operationally, and all aircraft reconverted to previous standards.

Ju87D-5:
Close-support aircraft. Basic Ju87D-3 airframe but with tapered and extended wings. Deleted wing dive brakes (except for first production series) Fixed armament changed to two 20mm MG 151/20 cannons. Reinforced ground observation panel in the cockpit floor, mass-balanced ailerons, undercarrage jettison facility and revised bomb rack arrangement on late production aircraft. Production ceased at the Weser Bremen-Lemwerder plant in July 1944 after the completion of 771 Ju87D-5s. Operational on the Eastern Front. Occasionally used 8.8 lb SD 4/HL hollow-charge bombs, fitted with rocket boosters, aginst Soviet tank concentrations.

Ju87D-6:
Proposed as a "rationalized" version in 1943, but not developed.

Ju87D-7:
Night ground-attack bomber. Conversion of the Ju87D-3 airframe and re-engined with the Jumo 211P of 1,500/1,410hp with exhaust flame dampers and night flying equipment. No dive brakes; jettisonable main undercarrage; D-5 standard fixed and defensive gun armament. First Ju87 night bomber, became operational on the East Front in December 1943. Also used on the Western Front, in the Balkans and Italy until the end of hosilities.

Ju87D-8:
Night ground attack. Conversions of D-5 airframes to similar standards as the D-7 (Jumo 211P engine with exhaust flame dampers, night flying equipment) In early 1945 some Ju87D-8s also flown in daytime with removed exhaust flame dampers.

Ju87E-1:
Proposed navalized version of the Ju87D-1, intended to carry one LTF5 torpedo. Project work began in July 1941, and a modified early "Dora" designated Ju87D-1to (for "Torpedo") was test-flown at the Travemunde test center in spring and summer of 1942. Developement abandoned when construction work on the carrier Graf Zepplin stopped for good in February 1943.

Ju87F:
Proposed developement of the Ju87D. Initial project submitted in late 1940 envisaged the use of the new Jumo 213 engine of over 1700hp then under developement and featured reinforced undercarrage with larger tyres and a completely revised wing structure of increased span. After examination the proposal was rejected by the RLM in spring 1941 because the estimated performance was considered insufficent improvement to justify production.

Ju87G-1:
Specialized tank destroyer evolved in 1942-43. Basicly a conversion of the Ju87D-3 with attachment points to carry two 37mm Flak 18 (BK 3.7) cannon in streamlined fairings outboard of the main undercarrage legs. (Cannon attachment points could be exchanged for bomb racks) Standard defensive armament; often had improved ground vision panel in the cockpit floor. The use of large-caliber cannons to combat the increasing number of Soviet tanks from the air was proposed by front-line aircrews in Summer 1942, and first trails with various aircraft types (Ju88P, Bf110F and Ju87D) were carried out in late 1942, when the Ju87D was adjudged by far the best. Deliveries of converted D-3 airframes commenced immediately afterwards. On operations, some Ju87G-1s were flown with, others without, the fixed wing armament. Operational principally on the Eastern Front, but small numbers also used in North Africa in spring 1943 and on the Western Front late in 1944 and early 1945.

Ju87G-2:
Tank destroyer. Aas Ju87G-1, but conversion of the Ju87D-5 airframes. Deleted fixed wing armament. Some machines fitted wth exhaust flame dampers and used at night. Operational areas as Ju87G-1.

Ju87H series:
Dual-control trainers for conversion training of ex-bomber and other pilots. The Ju87H-1, -3, -5, -7 and -8 were conversions of Ju87D-1, -3, -5, -7 and -8 dive bombers respectively incorporating the following major changes: gunner's seat replaced by foward-facing seat from the Ar96 trainer; dual controls and instrumentation; new rear cockpit canopy with side blisters; deleted armament and wing bomb racks. Some impressed into operational service in spring 1945.

-From: "The Great Book of World War II Airplanes"

If anyone wants, I have TONS of information on the variants before the D model (Ju87V series, Ju87A series, Ju87B series, Ju87C series) and after the H model (Ju87R series, Ju187 prototype)

All you need to do is ask....

Ok, Im done with all of those variants. Any more questions? requests on the Ju87?

P.S. As you can see above, there are a butt load of Ju87 variants. (even more that I didnt type up) I expect to see more than just one...... Some things wouldnt be to hard to put in the loadout... for example the flame dampers or the desert gear. Just make that particular object a Gun (like the skids on the Sopwith Pup or what I did with the bombs bays on the 'special' tall-boy carrying Lancaster) Then you just select your loadout, change your skin and wala! a whole new Ju87 variant to play with.
