Avio Posted September 21, 2014 Share Posted September 21, 2014 With dual-rotor, I would expect that the Ka should maintain nose straight upon vertical lift-off into a stable hover, unlike in the Huey with left rudder is needed. But strangely, I noticed the Ka tends to want to rotate clockwise on its own. I left it on its own and it could turn through several rounds, therefore it can't be due to wind, otherwise it would have just weather-vaned into the wind and stop there. Hope someone could help shed some light here. Thanks. Link to comment Share on other sites More sharing options...
RazorbackNL Posted September 21, 2014 Share Posted September 21, 2014 (edited) Could be it is yawing to the last selected autopilot yaw channel heading, but than it needs to stop at a surtain heading instead of keeping yawing in rounds.

BitMaster Posted September 21, 2014 Share Posted September 21, 2014 Dual Rotor doesn't mean that is is free of any imbalance between rotor efficiency, gear friction etc.. all of that combined with a rpm change to hover will cause some kind of drift, not much, but it will happen. Add some little wind and there you have the right and need to call yourself a Pilot. The 2 rotor disks do not have the same efficiency as the lower disk operates in the downwash from the upstairs disk. That alone has some effects, i.e. when you accelerate to 150+ km/h you will start to notice a roll to the right, the more you accelerate the more roll momentum you will gain. Still, compared to the UH-1 and Mi-8 it almost flies like on rails if you are familiar with the Red Lady Kamov Bit Gigabyte Aorus X570S Master - Ryzen 5900X - Gskill 64GB 3200/CL14@3600/CL14 - Asus 1080ti EK-waterblock - 4x Samsung 980Pro 1TB - 1x Samsung 870 Evo 1TB - 1x SanDisc 120GB SSD - Heatkiller IV - MoRa3-360LT@9x120mm Noctua F12 - Corsair AXi-1200 - TiR5-Pro - Warthog Hotas - Saitek Combat Pedals - Asus PG278Q 27" QHD Gsync 144Hz - Corsair K70 RGB Pro - Win11 Pro/Linux - Phanteks Evolv-X Link to comment Share on other sites More sharing options...
Avio Posted September 22, 2014 Author Share Posted September 22, 2014 Thanks a lot BitMaster for your illuminating notes. Indeed perfect symmetry can't be expected, just wondering if the imperfection is randomly modelled for each flight or if it is scripted to behave the same way each time. One thing for sure -- the Kamov is truly a dream helo to fly (and fight in). Great. Link to comment Share on other sites More sharing options...
flanker0ne Posted September 22, 2014 Share Posted September 22, 2014 The sudden clockwise rotation happen if a rotor overspeed occur, often at autorotation start and in too aggressive level quick stops.

Bucic Posted September 22, 2014 Share Posted September 22, 2014 Thanks a lot BitMaster for your illuminating notes. Indeed perfect symmetry can't be expected, just wondering if the imperfection is randomly modelled for each flight or if it is scripted to behave the same way each time. One thing for sure -- the Kamov is truly a dream helo to fly (and fight in). Great. There's no scripting within the Ka-50 FM. To supplement what BitMaster have said. If you need to counter yaw during lift-off it means the Ka-50 doesn't achieve balance in these conditions. Simple. Please also note... You've said yourself nose straight upon vertical lift-off into a stable hover It's rather obvious the maneuver involves rotor lift variation, hence torque variations. Thus any balance is out of question. If achieved it would only hold for a brief moment. Please note that the same model applies to the rotors/helicopter when it's in flight. https://akaagar.github.io/briefing-room-for-dcs/ F-5E simpit project https://forum.dcs.world/topic/318106-f-5e-simpit-cockpit-dimensions-and-flight-controls/ Link to comment Share on other sites More sharing options...
karambiatos Posted September 22, 2014 Share Posted September 22, 2014 I turned off the rudder trim, and since then ive had no random rotations. A 1000 flights, a 1000 crashes, perfect record. =&arrFilter_pf[gameversion]=&arrFilter_pf[filelang]=&arrFilter_pf[aircraft]=&arrFilter_DATE_CREATE_1_DAYS_TO_BACK=&sort_by_order=TIMESTAMP_X_DESC"] Check out my random mods and things Link to comment Share on other sites More sharing options...
