Referring to figure. Essentially (4) is the thermostatic valve that directs coolant straight to pump (7) bypassing the radiators (6) as long as coolant temp is below 80'C. If that isn't modeled, that's a shortcoming. "Tunnel dampers" must refer top the flap opening if coolant temp exceeds 115'C or if radiator switch is flipped to ON. "...that regulate the coolant temperature and oil." Bit of a word salad. It's a combined coolant / oil radiator? Original manual probably clearer.

DCS is up to date. Video drivers ... I may hold off a bit. Windows says I already got the best drivers. That doesn't mean much necessarily. If anything goes wrong I might have to restore a O/S harddisk image. If the the crashes other ppl have gets fixed, maybe this gets fixed. It mostly doesn't crash ... Finding the latest updated legacy drivers is a jungle. My current drivers are from 2017. Seems there are "legacy" drivers from 2018. The code is probably not touched. What is a Legacy GPU? Legacy GPUs are older-generation NVIDIA GPUs which are no longer supported in the regular NVIDIA Unified UNIX Graphics Driver. Instead, these GPUs will continue to be supported through special "Legacy GPU" drivers that will be updated periodically to add support for new versions of Linux system components (e.g., new Linux kernels, new versions of the X server, etc). https://www.nvidia.com/en-us/drivers/unix/legacy-gpu/

I regret causing confusion. I, took for myself only one possible meaning of DCS "dancing": Rapid back and forth medium inputs unrelated to anything except when seeing a trend favoring the opposition direction. In a real plane you'd have difficulty moving it this fast. The idea, maybe mostly my idea, to avoid prolonged inputs in any direction, this was discussed I remember. Prolonged input caused by lack of real world feedbacks that otherwise prevents this. This, ugly and unrealistic tactic kind of worked. But so does doing it more realistically. What works best of all is to find a cloud as reference to keep straight.

I never meant "full inputs", I meant rapid small movements. Tapdancing like. In real life (gliders) full input is a rare (rudder) exception only within the first few seconds (single digits) of the takeoff run.

About this "dancing on the pedals". Maybe depending on definition of "dancing". This is not something you do in real life. When I learned to fly gliders I brought with me very bad habits from an arcadish "flight simulator". I did rapid movements (maybe twitchy pots contributed) and you don't, ever. It's only ever minute smooth corrections. The only exception on the takeoff run, the first ~5 seconds before having airspeed over rudder, one might rapidly slam it fully to one side to keep straight. Maybe the lack of real life physical feedback makes rapid pedal dancing a thing in DCS. I've seen videos of aerobatic flying, punctuated "pumping" the stick through roll manouvers is something different. Learning to land the Spitfire smoothly is quite satisfying and worth it.

AUTO is forward, not rearward. All three switches are marked ON (rearwards) / OFF (forwards). The fuel pump and the pitot are ON rearward so I assumed for the radiator ON (rearward) = AUTO as well. There would be an "in flight" symmetry to that. All switches rearward = fuel pump on, pitot on and radiator AUTO. But no. ON for radiator switch apparently means flap fully open, auto off. Indeed key command [LCtrl A] AUTO does put switch forward (marked OFF) while [LShift A] OPEN does put the switch rearwards (marked ON). I tagged to this today when flap started to open in ON position with temps way below the 115°C overheat limit. I'm just asking for confirmation. This is how it works?

Having the ball centered on touchdown helps. Something I found immensely helpful learning Spitfire takeoff was fixing on a cloud to keep straight. I've recently taken to raising the seat for takeoff / landings too see better. Used to do that only for CV landings.

That's a major modeling shortcoming. Can't fly at alt or cold weather.

Took a turn for the worse. For some reason, maybe just me, I always had infrequent occasional, "stick disconnected" or whatever the exact message. It reconnects immediately and nothing usually happens. Except now it goes full throttle and I have to "retouch" throttle. <sad upside down Spitfire> <and sad upside down P-51> ... Now it happened when Alt-Tabbing away from DCS. Coincidence? --- Happened again, immediately on Alt tabbing away. Even an Alt+Enter shift from full screen triggers it.

It works. Asked how to put the CV in a silly loop long ago. It would be nice if it said "Go to waypoint X" so you didn't have to open the action to see which waypoint.

So I noticed multiple times when spawning P-51 start on runway engine spins up. When I touch the HOTAS throttle lever (Warthog) it goes to idle. Same thing Spitfire. HOTAS throttle idle but engine roars away until lever touched on mission start. Began with first 2.7 release I think. Yes, I checked the checkmark, I've relied on it for years.

Fixed? Animation inside cockpit when bound to TM Warthog slider seems to work now. Also a new(?) funny ticking sound when moving the lever.

Functions "Oxygen emergency valve" and "Diluter lever" are mixed up - fixed Yay, pointed that out Oct 22 2019. Not that it was game breaking ... Known Issue: DCS: MiG-21bis crash sometimes. Sure that's a bug?

Spitfire did that too IIRC. From the either or both of the Spitfire test pilot biographies (Quill and Henshaw), they did this, if required, to every Spitfire off the production line (and after repairs). Bent little metal pieces on the wings to make them fly straight. Which also suggests to me this was a practice done to lots of (all?) airplanes at the time. Still do I suspect. Agreed, makes perfect sense.

So there's document evidence it had "ground adjustable trim tabs". Statementys in the original I-16 thread were less concrete. I assume and would be disappointed if ED hadn't talked to an I-16 pilot. I had the impression that was a requirement for ED before releasing any module.

It's supposed to be warm I learned from Asterix.

My comment patch thread.

Depends on definition of "hands off" and how long. I wouldn't take a nap. P-51 and Spitfire are stable ... for a while. "Positive stability", don't think either 51 or Spit have it. I do know there are planes that do but that's not the point of a fighter plane.

You can't say "it flies on rails". It now flies somewhat straight at 420 km/h (MP 91 RPM 2200). It mostly sideslips leftwards. I guess there is a speed where's it's straight (sideslipwise). At 200 km/h it noses down and sideslips right. With gear down it noses down at any speed. I too noted the change in flaps. I used set to typically 22 degrees, never more than 30 or less than 20. Now (I have to experiment more) I set about 10 degrees. Full 60 degrees was ridiculous on the pre tweak as well. Did it work like that in real life I wonder? There's a number of flying I-16's. The truth is out there. It's been tweaked clearly. I like to think they changed "ground adjustable trim tabs" assuming that's a real thing (*1). It seems odd the real thing would constantly need a large amount of back stick. This isn't necessarily the same thing as "can't fly hands off", neither can any non auto pilot plane. But if there is documentation "you always had to have stick back", yes this is how DCS I-16 should work. Bf 109 is "always stick forward". Absolutely no "two versions", just make it as right as it can be. Seems as squirrelly as ever on roll out after landing. ~ 1) Ground adjustable trim tabs are a real thing. Comments have suggested the real I-16 had it.

The good news is with 2.7 this is fixed. The bad news is clickable cockpit is gone (again) (full screen monitor resolution differing from game resolution). Actually it looks like back to the 2.5.6 (err I mean 2.5.5, I think) situation. With a new twist. Going back from full screen to windowed the clickable stops working correctly. What happens is the click position is skewed upwards. On my 32" screen I have to click ca 5 mm higher up. As noted I vastly prefer the minor "cursor jumps" to not having full screen "clickable cockpit".

Screenshot didn't capture popup (orange) "Different actions have identical descriptions". Duplicated but empty. Again, I stress, opening and closing Canopy works fine for me.

The pedals indeed go back when released. Never watched for this before but I imagine they should stay pressed down with parking brake applied (I assume they used to). Functionality fine. A pedal animation thing.

99% sure it didn't used to work like that. Rotary is available with keyboard binding ("[1]") (was it always?). Fix: remove rotary when mouse clicking. Ie remove jumps from first-last and last-first while mouse clicking. Is mouse click rotary a new feature? Make more sense if it didn't (again 99% sure it didn't used to).

P-51 have (had) the best trim. Hold a few seconds and speed much faster. Not working for for pitch trim with 2.7.
