Pocket Sized Posted February 8, 2017 Posted February 8, 2017 I am currently running 1.5.6 update 2. It's also present in 1.5.5 and 1.5.4. Problem: Ailerons seem to create a tremendous amount of drag when deflected. Replication: Accelerate to 600-800 kmh at low altitude and stabilize your airspeed. Do a full deflection aileron roll and note how much airspeed is lost almost instantly. The amount of drag is comparable to extending the airbrake! Does anyone know of this is accurate behavior? It makes high speed dives difficult as countering uncommanded roll results in severe speed loss. The F-86 has much bigger ailerons that deflect further but they don't have any noticeable effect on airspeed when used, especially not to this degree. I will probably upload a video later today replicating the problem. DCS modules are built up to a spec, not down to a schedule. In order to utilize a system to your advantage, you must know how it works.
Werewolf1025 Posted May 9, 2017 Posted May 9, 2017 Alright after you brought this up I did some testing of my own. Your results seem similar to mine, the drag produced by even the slight movement of the Ailerons on the Mig-15bis seems massive. In the video below I demonstrate this and compare it to the similar F-86, an aircraft with larger ailerons. The Mig demonstrates a loss of +80kts in a high speed roll while the Sabre would appear to actually gain speed in some instances. https://www.youtube.com/channel/UCz7qqa3ryy_qgwQI5HDd7GA
SeaQuark Posted May 10, 2017 Posted May 10, 2017 Yikes, that just doesn't seem right. Hope this gets looked at soon. [sIGPIC][/sIGPIC] WNG. CMNDR. 39th Virtual Fighter Squadron SeaQuark Sims DCS YouTube channel
Pocket Sized Posted May 10, 2017 Author Posted May 10, 2017 Holy crap, I knew the drag was bad but I had no idea it was THAT significant. If/when this gets fixed, I wonder how the "balance" between the MiG and Sabre will be effected? It seems like they're pretty even in game despite the MiG having to deal with such a massive handicap. DCS modules are built up to a spec, not down to a schedule. In order to utilize a system to your advantage, you must know how it works.
Schmidtfire Posted May 10, 2017 Posted May 10, 2017 Wow. That definitely looks like a bug! Hope that it gets reported and fixed soon.

gulredrel Posted May 22, 2017 Posted May 22, 2017 Did a quick flight yesterday. No joy to fly at the moment. Doing two aileron rolls slows you down faster than airbrake usage.:cry:

Talisman_VR Posted June 30, 2017 Posted June 30, 2017 fixed it!:) But probably in the FRIDAY-update it fix will not be included:( PS. WILL BE included!)) Hi PilotMi8, Will the fix be included in the new version DCS 1.5.7 now planned for release next week? I am a big fan of your Mig-15 :) Thank you in anticipation. Happy landings,
probad Posted June 30, 2017 Posted June 30, 2017 i believe that is what he means, it will be in 1.5.7 patch.
gulredrel Posted July 1, 2017 Posted July 1, 2017 It isn't mentioned in the 1.5.7 change log :( https://forums.eagle.ru/showpost.php?p=3182611&postcount=49
probad Posted July 1, 2017 Posted July 1, 2017 this isnt anything new, patch notes regularly omit 3rdparty module changelogs. heatblur also noted viggen fixes for 1.5.7 and those weren't posted in the patch announcement either. i would think pilotmi8 to be a trustworthy source of information, if he says its in the incoming patch, then it will be in the patch.
Istari6 Posted July 2, 2017 Posted July 2, 2017 Yes, could we get some confirmation this will be fixed in the 1.5.7 patch once released? I just started flying the MiG-15bis (after months of flying the Sabre), and I've been astonished at the speed bleed during simple aileron rolls. I scrubbed 100 kts of airspeed in a simple 180 deg roll. I understand these kinds of bugs can appear with constantly evolving software, just hoping it'll be fixed soon.
Talisman_VR Posted July 3, 2017 Posted July 3, 2017 i believe that is what he means, it will be in 1.5.7 patch. As I understand it, he was referring to the fix in relation to the DCS version 2.1.0 update for Friday 26th May. I am asking if it will be included in the version 1.5.7 update due this Friday 7th July. His post about the fix was dated 24th May, at which time there was no news of version 1.5.7 update, only 2.1.0. There is no mention of the fix in the version 1.5.7 changelog, so I am concerned about that. Some information on this from the developers would be very welcome, as many of us are not involved in testing version 2.1.0. I hope that version 1.5.7 users will not be left out of this fix. Happy landings,
Istari6 Posted July 3, 2017 Posted July 3, 2017 Agreed. I tested the MiG-15bis in the latest 2.1.0 Alpha last night, and it flies VERY differently. The problem is definitely fixed there. I can do complete aileron rolls with almost no speed loss. It feels like it should - a rocketship just bursting with power (albeit a glacial roll rate :>). Hopefully we can get confirmation for the 1.5.7 release on July 7th. I'm looking forward to getting back into Museum Relic (which is dependent on the Caucasus map).

Nice to know that the performance is good in version 2.1.0. Thanks for the feedback and good news :) Happy landings,
gulredrel Posted July 13, 2017 Posted July 13, 2017 Yes, works good in 1.5.7. Forgot to deploy flaps on landing, only speedbrakes... plane was too fast on approach and floating and floating and floating... Will try with flaps next time. Now MiG-15 will get more airtime again.
Dunravin Posted October 12, 2017 Posted October 12, 2017 Greetings I'm having lots of stalling issues and loss of control hence why I'm here. Found the performance stats pdf here - https://belsimtek.com/upload/docs/DCS_MiG-15bis_AERODYN_OPER_LIMITATIONS.pdf I quote from page 4 - Minimum airspeed limitations "Minimum control speed at which the control surfaces retain sufficient effectiveness is 300 km/h at altitudes above 12000m" I'm losing control at @400kph at even low to medium alts in dogfights and the AC is too slow to recover in a dive. Hella draggy. I'd like that extra 100 kph margin if possible :D Now I remember in beta phase this was a joy to fly, bags of power, now it feels like its too draggy and underpowered. I understand the beta FM was not accurate but IMO the current iteration does not tally with the documented statistics either and needs bumping up. I also notice slightly worse performance in 2.1 but I put that down to the QFE of Nevafa being around 900-1000 meters higher above sea level than Caucasus. I'm learning to let the MiG fly me and I just help it along but still I feel something is a miss here. I can live stream it if dev's are interested in seeing where it all falls apart in combat. Many thanks The FALSE is real, but it's not THRUTH right? Intel i7 8700K OC4.4GHz | 16GB | GTX1080Ti | Logitech G940 | TrackIR5 |
