The instability never existed, Mk IX Spits have a bigger engine/nose not tailplane, if you like I can provide a diagram so you know which end of the aircraft we are talking about. Just because an issue does not exist does not mean we don't understand it. Anyway, feel free to produce the evidence of the claim.

Yes, not sure how your highlighted 'but' changes anything.

The misunderstanding is coming from you, don't let your childish personal agendas dictate the direction of this thread.

The document you linked is the evidence I know the subject well enough, when I make a mistake I always own it, the advice is irony.

This is extracted directly from the .pdf file you have linked, it is verbatim what I am saying, no confusion on my part sorry or in my understanding of it 'neutral elevator' trim, this may not be 'zero trim' on some aircraft but it may be on others, that will be entirely dependent on the individual design I accept.

There is not really a range of cruise speeds, you either cruise at just above Min drag speed or you are not in a cruise at all, it seems the only thing being wasted here is breath. it would help us greatly if we could talk about the same subject, clearly everybody else is discussing the cockpit adjustable stabiliser trim. when...not if I fly single engine aircraft, often on training flights in my capacity as a flying instructor I demonstrate the need to trim the aircraft pitch down to maintain the level cruise, this is because the neutral trim position we have just used in the climb starts to produce a marked pitch up force as the aircraft accelerates from climb speed to cruise, and this happens because the weight and balance of the aircraft is correct.

Not sure what you mean, at climb power I'm climbing, at cruise power with neutral trim I still pitch up because the function of trim is produced according to airspeed. Cockpit adjustable manual trim is not 'pre-trimmed' for cruise. if an aircraft is properly trimmed then it will maintain whatever condition you are trimming it for, you can trim for climb, cruise or descent and in various configurations, the point I am making is that aircraft that have neutral trim set will pitch up at cruise power.

Sorry Otto, I don't mean to sound like another hostile voice ganging up against you but in every aircraft I have flown the neutral trim position produces a pitch up in the cruise, the neutral position is almost always the setting used for maintaining a climb which is why most pre take off checklists call for trim to neutral.

Not cockpit adjustable ones.

I have found that going in to the settings menu and poking around (I used controller setup menu) sometimes allows me in to the game afterwards.

Precisely, had it been found to be a worthwhile/necessary modification then the present day regulatory bodies would be insisting the dual seat TR9's would have it, I fear we are witnessing another attempt at perpetuating a myth about Spitfire instability.

The Mk IX had no longitudinal instability issues, I'm pretty sure the only significant modification of tailplane size came with Griffon powered variants.

Wait until we have a CV1 in hand and make a judgement then. VR is coming regardless, flight sims may as well start adapting to the new tech now even if it means we sacrifice a little in the early stages.

Hope this is the suitable section to report, haven't seen any one else report a similar issue but I have noticed that water reflections suffer a similar problem to how shadows used to render, that is they seem to be slightly offset in each eye, the shadows are now working perfectly for the most part but I have noticed a glitch when your shadow falls on the wing of your own aircraft viewed from the cockpit, it's like only parts of the shadow shows, the glitch is particularly noticeable when the shadow falls approximately half way along the wing, I haven't tested all aircraft but have noticed the exact same thing on a few.

Worked for me, thanks :thumbup:

Some kind of sinister black magic has been performed, the fps gains in the Oculus rift I just witnessed are not natural, it didn't even make the fans on my Graphics card spin, the sim didn't skip a single beat, very slight flickering judder with fast head movement but the immersion just overwhelms small stuff like that, roll on DCS2 and oculus CV1

I thought 1st stage of flap was quite small, 15 degrees on a Hunter I heard, I have seen pictures of Hunters looping with and without flaps, I just thought the flap setting on this hunter looked a bit excessive, of course we will all get to find out in due course.

Aircraft are not allowed to fly beyond the manufacturer specified life spans, all flying vintage aircraft are operating within their fatigue life indexes, not all aircraft even have a manufacturer imposed limit. What happened to this Hunter does not appear to be a structural failure and therefore is not likely to be a factor of it's age, in some cases civilian owned and operated ex military jets are less worn out than the Hawks the Red Arrows are flying.

but the flaps were deployed from the beginning of the loop, that is the point, even in the case of a problem developing it's a bad idea to go flipping flap levers in the middle of a manoeuvre , you need to get the machine to a normal attitude and under control first.

pictures seem to show the Hunter had it's flaps down the entire way through the loop.

The Fw190 seems to have quite an unusual main wing spar, it is cranked longitudinally and is situated quite far forward compared to typical designs, particularly on the outboard section of the wing, to me it would seem the wing would twist with increased washout under aerodynamic loads but maybe g loads could have pulled the trailing edge down?

I have parts for sale.

Maybe the South American runway was strewn with those, though I would have practiced a rejected take off instead of a V1 cut......unless of course the engine ingested a hood ornament just before V1, in which case it's not really practice.

Do me a DCS Beaufighter and I will start a new religion in your name Pman!

it's still cool we will get to fly them so yeah.....cool.
