Awesomejlee Posted April 22, 2021 Share Posted April 22, 2021 Why does the nose wobble so badly in this thing? I understand at high AOA it is supposed to, but I can't shoot down a plane flying straight because the nose just wobbles back and forth CONSTANTLY. I'm not going too slow. 200 knots. I've tried it all all speeds. It's trimmed out. None of the other WW2 birds do this. I've never seen it do it in gun cam footage in real jugs. What's going on with it?

DD_Fenrir Posted April 22, 2021 Share Posted April 22, 2021 1. Which sub-variant? 2. Gyroscopic precession 3. Phugoids 4. 200mph is not fast for a P-47, especially as you add AoA. 5. Check auto-rudder in settings. Link to comment Share on other sites More sharing options...
grafspee Posted April 22, 2021 Share Posted April 22, 2021 (edited) Are you sure that you are not over controling your plane, very often issue with standard joystick available for gamers.

Awesomejlee Posted April 22, 2021 Author Share Posted April 22, 2021 D40, auto rudder off, warthog hotas. I’m not hamfisting it. I can settle the pipper on a target that’s flying straight, let go of the stick, and the plane wobbles around to the point that I can’t get a tracking shot.

Having the cowl flaps open at >200mph causes buffeting. Link to comment Share on other sites More sharing options...

Davee Posted April 22, 2021 Share Posted April 22, 2021 I agree with the nose wobbling when it should be stable when all trimmed out. Link to comment Share on other sites More sharing options...
Barrett_g Posted April 23, 2021 Share Posted April 23, 2021 I experienced the same twitching and wobbling. I added some curve to my joystick settings. I flew the P-47 again and it still twitched... but not as bad. I added more curve... but I was disheartened because I didn’t think I should have to add so much curve and I was afraid maybe DCS did something wrong..... until I saw this video that explains why WW2 birds feel twitchy in DCS: https://youtu.be/Gs2m-xlyK7o I added a little more curve (about as much as in the video) and it flew more solid... but still had a bit of twitch to it. looking in the external view I noticed my rudder would flop over when I was moving my ailerons. I checked my joystick settings and realized there’s a sharp spike in the rudder axis near the dead zone of my joystick. I think it’s a worn pot or maybe a dirty pot. I added (I think) 15 to the dead zone and now it flies perfectly with my old ass $20 joystick. Link to comment Share on other sites More sharing options...
grafspee Posted April 23, 2021 Share Posted April 23, 2021 (edited) From NACA raport And this is exactly what we do with short sticks. I have big problem with this in warthog stick, centering spring is so strong that i can not control my stick movement there. I think i need to change this spring to be a little weaker.

I have the same problem with my Warthog on a 20cm extension if my rudder coordination is bad (which is most of the time). Link to comment Share on other sites More sharing options...

A short extension will make all the difference, 7-10cm. Makes the standard spring perfect. You need to mount below your desk though. Link to comment Share on other sites More sharing options...
