Boomer_G-Loc Posted December 9, 2021 Share Posted December 9, 2021 It happens during the P51 vs P51 dogfight instant action in the Caucasus region. 1st time it was about 30 seconds into the flight right after the merge. I didn't see him fire at me, but assumed I had been hit. After that, it kept happening, but only seconds into the game (like 2 or 3 seconds after start). Each time I would do an emergency landing into a field. And I don't know if the game allows it, but on the way down, I'd try for an emergency restart, but get absolutely nothing. When starting the gameflight, the engine is already at the default game starting throttle setting, and again, this is now happening within the first 2 - 3 seconds of gameplay. All my engine gauges appear normal when it happens, only thing I see happen is the ammeter drops from normal to zero when the engine quits, but all else seems normal, unless I'm missing something deeper here.... I started saving and reviewing the tapes, and the opponent is not shooting at me, so I am not hit at the merge. Can someone tell me what's going on here? I have the 2.7 DCS version that is *not* the open beta one. Thanks, Link to comment Share on other sites More sharing options...

Paganus Posted December 9, 2021 Share Posted December 9, 2021 Check for a crossed controller mapping. Something that will shut it down quickly like the magneto or fuel cutoff. 1 Link to comment Share on other sites More sharing options...
Boomer_G-Loc Posted December 9, 2021 Author Share Posted December 9, 2021 I checked all those in the cockpit views, all switches were in operating position. Will the cockpit view not represent the actual condition? I have not mapped engine controls to my current stick. But I will review the file.

Paganus Posted December 9, 2021 Share Posted December 9, 2021 Does it only happen in the one mission, or all P-51 missions? Link to comment Share on other sites More sharing options...

Will the cockpit view not represent the actual condition? Well, there's still a months-old bug in P-51 with carb levers moving but not actually working if operated by mouse, but that in itself shouldn't kill the engine, it "only" reduces your power somewhat. What Paganus means is - there are always multiple duplicated assignments in default controls table and unless you spend some time browsing through it and deleting them, you might be cutting off your engine with some button press without knowing about it. In either case, posting a replay track would help a lot, otherwise we'll be running in circles here. i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.

Usually this destroys your Engine pretty fast when the Lever is in Idel RPM and the Engine is running full Boost with the Throttle. RPM Lever should be also fully Foward like the Throttle. Once you have tasted Flight, you will forever walk the Earth with your Eyes turned Skyward. [sIGPIC][/sIGPIC] 9./JG27 Link to comment Share on other sites More sharing options...
Mr_sukebe Posted December 9, 2021 Share Posted December 9, 2021 OP, you sure that you didn’t overheat the engine? It’s VERY easy to do, bizarrely so when the Spitfire seems to be near impossible to overheat, despite using the same engine System: 9700, 64GB DDR4, 2070S, NVME2, Rift S, Jetseat, Thrustmaster F18 grip, VPC T50 stick base and throttle, CH Throttle, MFG crosswinds, custom button box, Logitech G502 and Marble mouse.

Doughguy Posted December 9, 2021 Share Posted December 9, 2021 its unusual that your engine would die if you spawn in mid air if you do not make any adjustments and just fly straight level. the system starts with a default setting and takes a few seconds to read your inputs (eg throttle axis etc) and adjust to these unless you make adjustments on your own. make a quick editor mission for simple flight, check, and save a track so we can see. anything else is pure guessing. https://sr-f.de/ Link to comment Share on other sites More sharing options...

If he has sync controllers option checked it will sync all inputs as mission starts, this can lead to unaware inputs applied. But wild guessing is just pointless, track is very much needed.

Nothing could overheat in that short time - sounds like a controls conflict or mis-mapping (fuel cut-off?). All speculation without track file.

I have the 2.7 DCS version that is *not* the open beta one. Thanks, I was constantly having that problem, and panicking, when I finally realized that my Mixture was randomly going to Idle Cut-off. I still have the problem - no idea what is causing it - but I now have a switch on my throttle with 'up' being RiUN and 'down' being Idle Cut-off, and a button for Full Military Power. And as soon as I hear that Merlin cough, I just click on 'RUN' to fix it. I also thought that I may have a duplicate binding I didn't know about, so I went to that binding and deleted everything connected to Mixture, including the keyboard commands. It still happens randomly, but not as bad. Tell the truth, I'm beginning to suspect my X-56 throttle control, because I have also had both gear activations and flap activations with no physical inputs. ..both controls are on the throttle control.

Sarge55 Posted February 1, 2022 Share Posted February 1, 2022 (edited) I recall many years ago when using my old X-52 that there was an issue with ghost commands as they were called. That maybe what you have going on. Are you using the X-56 software to program any of the controls? IIRC I had to use the saitek software for a couple of commands to simulate an extra axis or something So it could be the X-56, just a thought… Edited February 1, 2022 by Sarge55 [sIGPIC][/sIGPIC] i7 10700K OC 5.1GHZ / 500GB SSD & 1TB M:2 & 4TB HDD / MSI Gaming MB / GTX 1080 / 32GB RAM / Win 10 / TrackIR 4 Pro / CH Pedals / TM Warthog Link to comment Share on other sites More sharing options...

I have the same 3 random problems using my X56: mixture going to cut-off, gear retraction on take-off roll, and random flap activation. I Also have the 2 fingertip buttons (labeled H and I on the throttle) mapped to chase and cockpit view. I get random jumps to the chase view in DCS and also MSFS.

71st_Mastiff Posted October 31, 2022 Share Posted October 31, 2022 (edited) same P51D30 engine just quits, instant missions, seems to be some issue with the oil and water coolers not working in auto mode again, when using the key binding customization assigned. de-Brief state engine failure, but all steam gauges show nominal. Screen front UI is green in the hanger, track I guess to big but at the end I'm rammed by a 109 K, didn't even engage me; just rammed right through my wing no damage to the 109 K4. https://www.mediafire.com/file/y0jtv6573o8n97g/28p51d30.zip/file Edited October 31, 2022 by 71st_Mastiff " any failure you meet, is never a defeat; merely a set up for a greater come back, " W Forbes "Success is not final, failure is not fatal, it is the courage to continue that counts," Winston Churchill " He who never changes his mind, never changes anything," MSI z690MPG DDR4 || i914900k|| ddr4-64gb PC3200 || MSI RTX 4070Ti|Game1300w|Win10x64| |turtle beach elite pro 5.1|| ViRpiL,T50cm2|| MFG Crosswinds|| VT50CM-plus rotor Throttle || G10 RGB EVGA Keyboard/MouseLogitech || PiMax Crystal VR || 32 Samsung|| Link to comment Share on other sites More sharing options...
AJaromir Posted October 31, 2022 Share Posted October 31, 2022 (edited) Yesterday I did fly P-51D for hours, without issue. Only once when the oil was not warm enough for take-off. In debriefing was "engine jammed". But that was pilot's mistake. I also was able to run it on full WEP for 10 minutes. Until the engine is not too hot or too cold, it will run smoothly for a very long time. Edited October 31, 2022 by AJaromir Link to comment Share on other sites More sharing options...

P51D30 I found only that when you use custom keybinds they seem to work but the oil and water cooler are not actually returning to automatic. and I don't see the oil & water inlets working. the mention of the BF109K is it didn't engage me it just rammed right through me..
