Raisuli Posted November 14, 2018 Share Posted November 14, 2018 Hornet seems to constantly bank either left or right in Instant Action. Aileron trim does nothing. Symmetrical load out. PEBKAC. What does your rudder trim look like? Are you rudders centered electrically and mechanically? Same with the stick. Equal thrust from both engines? What does the FCS page on the DDI show for control surface position? A screenshot of the DDI page and the IFEI might help diagnose the issue, but Occam says it's not going to be a difficult fix.

fael097 Posted November 14, 2018 Share Posted November 14, 2018 if it's a small bank then it's wind, the slightest wind will make it bank in dcs. I've never flown myself a real plane but I'd assume that if trimmed properly, a plane would be able to fly straight without auto heading or constant pilot input. that never once happened to me flying the dcs warthog and hornet Rafael Ryzen 7 1800x @ 4ghz | MSI GTX 980ti | 32gb DDR4 Ballistix 2400Mhz | Asus ROG Crosshair VII Hero (wi-fi) | 480Gb Kingston NVMe ssd | Western Digital 1TB x2 | EVGA 850w PSU | Noctua NH-D14 | NZXT S240 | Windows 10 Pro 64bit | 4k 50" Philips android TV | Dell P2418D | Oculus Rift S | Thrustmaster Warthog Hotas Link to comment Share on other sites More sharing options...
Flamin_Squirrel Posted November 14, 2018 Share Posted November 14, 2018 PEBKAC. No it isn't, and don't be so dismissive. I occasionally get this too, the cause is an off centre rudder (as shown on FCS page) when spawning. My hardware is fine (centred) and so is the trim. I'm not sure why it happens, but it doesn't happen frequently so I re-trim and ignore it. if it's a small bank then it's wind, the slightest wind will make it bank in dcs. No, wind doesn't work that way. An aircraft moves with the airmass in which it flies, with only ground track being effected. Takeoff/landing and windsheer being exceptions, but that's not relevant here. Link to comment Share on other sites More sharing options...
Pandemic Posted November 14, 2018 Share Posted November 14, 2018 With my limited flight experience, you’ll never be able to get a perfect trim going. Little variations will throw you off. In aircraft with no autopilot its recommended to never take your hands off the stick unless cleared by a co-pilot. I’m unsure of how FCS works in the Hornet so I don’t know if it’s realistic for specifically it, but I do know that this isn’t some UFO behavior.

Pasquale1986 Posted November 14, 2018 Share Posted November 14, 2018 This is pure speculation and might be super dumb as i use a TM Warthog Throttle, but i would assume this is related to ever so slightly asymmetric thrust. Aren't both engines modeled with a slight Variation between them? Main Module: AH-64D Personal Wishlist: HH-60G, F-117A, B-52H Link to comment Share on other sites More sharing options...

The aircraft is doing what it is supposed to do, so if it's doing something you don't want you need to figure out what isn't set correctly, which is why I suggested looking at the FCS page and checking the rudders. Those are generally stuffed under desks and getting one pushed out of position isn't uncommon. That's the beauty of a sim. We don't have to worry about bent aircraft here.

When this happens to me, the rudder is off, but everything is centred (including rudder and rudder trim). You're right that it can be corrected, but it's still strange. Assuming this is what's happening to the OP of course. Link to comment Share on other sites More sharing options...
fael097 Posted November 14, 2018 Share Posted November 14, 2018 (edited) No, wind doesn't work that way. An aircraft moves with the airmass in which it flies, with only ground track being effected. Takeoff/landing and windsheer being exceptions, but that's not relevant here. what I meant is, afaik real wind shouldn't work that way banking the aircraft like that, but in dcs it does. it's easy to diagnose if it's wind related 1-fly straight 2-notice banking 3-turn around 180º 4-check if it banks to the opposite side if it was a trim issue or asymmetric loadout/thrust issue, you would bank to the same side regardless of your heading.

Aren't both engines modeled with a slight Variation between them? My assumption as well since the engines never run exactly the same parameters even if just one throttle axis for both is being used which I tried back then as soon as I noticed the differences especially in EGT.

fael097 Posted November 14, 2018 Share Posted November 14, 2018 Categorically, patently, and absurdly untrue. Airflow around an aircraft isn't a homogenous, constant value, it's constantly changing, and unless you have a good autopilot you will have to make constant corrections no matter how well you have the aircraft trimmed. while I agree with this, airflow variation is one thing, but that doesn't happen in dcs at all. what happens is a constant, homogeneous and annoying bank towards the side that the wind blows Rafael Ryzen 7 1800x @ 4ghz | MSI GTX 980ti | 32gb DDR4 Ballistix 2400Mhz | Asus ROG Crosshair VII Hero (wi-fi) | 480Gb Kingston NVMe ssd | Western Digital 1TB x2 | EVGA 850w PSU | Noctua NH-D14 | NZXT S240 | Windows 10 Pro 64bit | 4k 50" Philips android TV | Dell P2418D | Oculus Rift S | Thrustmaster Warthog Hotas Link to comment Share on other sites More sharing options...

Sure, but turbulence doesn't make you only roll in one direction only or the other does it. That's how I read the OPs post (rightly or wrongly).
