I'm working on a Griffon XIV mod as we speak...

I've discovered another inaccuracy with the 3d model. Not only is the wing too thick at the tip, it also appears to have zero washout. Compared the model with my accurately washed out wing ribs in Blender: vs. From this I've also been able to discern that, in the DCS model, the cannon/stub has no incidence relative to the fuselage and wing datum lines, when it should in fact be 1 degree.

The model/systems REALLY could do with an overhaul, inside and out. I'd personally pay for a "2.0" style upgrade.

For anyone interested, this is the sight picture of Spitfire IXe TD314. The gunsight is clearly misaligned slightly, but it seems to confirm my suspicion that the reticle texture itself in-sim is too large i.e. the ring has too great a diameter.

MH487 makes a lot of sense! As a contemporary of MH415 and 434, it would have been constructed with the early air intake, which it still has in the photo. (MH434 in March 1944 at Hornchurch with No.222)

The supercharger control switches are currently mislabelled "Supercharge" vs. The labelling for the airscrew control may be somewhat correct for an aircraft with interconnected throttle and prop controls (which our aircraft SHOULD be but that's another story), whereas the label for earlier aircraft not so equipped is quite different: vs.

Mk IX AB505 See section 13: Sighting View 13......... The Spitfire IX is fitted with the G.M.2 pilots reflector sight and although the aircraft is longer in the nose than the Spitfire VC, the 100 m.p.h. ring of the sight is still just clear of the nose.

Yes I am well aware of this. My point is that the limited number of E wing conversions from standard Mk IXs retained the bays, blast tubes and gun ports for the 303s, which had to be blanked off. Hence why Johnson's Mk IXe in the photos has tape over the 303 gun ports. And yes, the Mk Vc could carry two cannon per wing, but as I've stated before the Mk IX could not for reasons already mentioned. Nor the standard Mk IX or Mk IXe variants could carry two cannon. It was for a very short time intended that it could use the eight .303 fitment as was also provided for in the Mk Vc but this was never even trialled let alone used in combat. To clarify further, there is no "Mk IXc", only Mk IX and IXe. As all Mk IXs were originally built with the same wing and armament a suffix wasn't used till the E wing was introduced. The prefixes F, LF, HF etc. came into use in March and April of 1943. The Mk IX wing is not a "C" wing in the sense of the Mk Vc in that it is not universal. Mod 683 was eventually embodied in late 1943 and officially standardised armament on the Mk IX (and Vc for that matter) exclusively to 2x 20mm and 4x .303s., although some squadrons removed two or all four of the Brownings in service to reduce weight. The removal of the outer cannon stub and use of slimline feed motor blister began in April of 1943, though this modification was cancelled in November with the future introduction of the E wing in mind, to easier facilitate conversion to that configuration.

Very clearly a Mk IXe - most likely a standard LF IX converted to E wing status, as was very common in the run-up to D-Day. The E wing conversions maintained the blast tubes and gun ports for the .303 guns, so they still had to be covered over with tape. In any event, the Mk IX was not capable of mounting four cannon, due to the cannon heating plumbing running through the outer cannon bay, and aside from one prototype no Mk IX was ever so equipped. For the E wing the gun heating system was rearranged, but still precluded the fitment of four cannon. The Mk IX "Universal wing" is in fact not universal at all, and "Mk IXc" was never a designation that was used officially.

Quick note - the Spit figures here are for open radiator flaps. I did some testing with them shut and these were my figures (brown line): These match up better with historical data.

Here's a V2 with improved reticle texture. Don't use full gunsight brightness; I use the "Day" setting on the dimmer switch. When assigned to an axis, the reticle is at full brightness at 100%, then turns off just under that, then switches back on as you reduce the brightness on the axis: use the brightest setting you can achieve before it momentarily switches off! The transparency of the texture doesn't play well with the maximum setting. Spitfire reticle 20 degree ring v2.zip

This is the case! The battery hatch is just afore the tail unit on the starboard/right side.

This mod changes the gunsight reticle from 30 degree ring to a 20 degree ring. When the target is in range and is at an aspect of 20 degrees angle-off (and below ~280 mph IAS) place it on the ring and fire. At higher speeds more deflection will be required. Range is also a factor. With your TrackIR/pilots head as high as it will go with the lid shut the ring will just clear the engine cowling, allowing you to see the target as you take a shot. Since refraction isn't modelled, this is the best we'll get. The real life tactical trials with AB505 stated that despite the lengthened cowling, the ring of the sight was still clear of the engine cowling, which is verifiable with in-cockpit photos. I've also taken the liberty to make the graphics more accurate, with the correct chiselled-edged crossbars and vertical bars which do not intersect the ring. They are still WIP however so expect an update.

Both! The battery is always "live", the switch on the throttle quadrant hits the relay for the lighting in the cockpit and that's it. It's even called the "Undercarriage Indicator Master" switch.

The switch doesn't actually turn the battery on or off - it only affects the indicator lights in the cockpit.
