spencer151801 Posted April 8, 2023 Share Posted April 8, 2023 KSP version: 0.1.1.0.21572 OS: Windows 10 CPU/GPU: AMD Ryzen 5 3600/Nvidia RTX 2070 Super Description: Elevons pitching is inverted, while roll and yaw are not. The elevons are placed behind the CG. Pitching motion is inverted, which makes SAS useless as it tries to pitch down, causing it to pitch up. Roll and yaw control are correct. I have a video on this Imgur link that shows the issue. Steps to replicate: Try to use elevons as a control scheme for your delta wing. Find your pitch inverted. Crash your poor airplane. (I genuinely don't know if or how it can be replicated) Fixes: None that I know of. Regardless of whether I make a new vehicle, restart the game, or make a new campaign, this problem persists. Mods: N/A There was another issue I found where one or more wings would magically invert itself if moved, but I'll leave another bug report for that. If I'm doing something wrong and it's simply a skill issue, please let me know! Otherwise, I hope the source can be found and fixed! Link to comment Share on other sites More sharing options...
spencer151801 Posted April 10, 2023 Author Share Posted April 10, 2023 Somehow this stopped happening. I have no idea what I did, but now it works. I'll investigate what fixed it and update here if I find anything. Link to comment Share on other sites More sharing options...
Davidian1024 Posted April 12, 2023 Share Posted April 12, 2023 This is definitely still happening. I was fighting with this before 0.1.2 released today, and I'm running into it right now. I have a craft that I seem to be able to consistently reproduce the issue with. I put the wings way behind the enter of mass in order to rule that out. Changing the root length of the wings of the craft seems to allow me to cause the problem to show up and go away. A root length lower than 0.32 seems to work normally. At 0.32 I sometimes see even stranger behavior. Pitch up causes one elevon to go up and one to go down causing the craft to roll instead of pitch. Above 0.32 I see the inverted pitching you're describing. https://pastebin.ubuntu.com/p/dV26MYfY2Q/ Link to comment Share on other sites More sharing options...
Davidian1024 Posted April 12, 2023 Share Posted April 12, 2023 I think I can consistently reproduce this bug. Here's a craft that has the issue: https://pastebin.ubuntu.com/p/GsYwShpPTN/ Root length seems to be the determining factor. 0.55 seems to be the threshold with this one.

Davidian1024 Posted April 12, 2023 Share Posted April 12, 2023 And here's a third using large wings for completion. The cursed root length seems to be 0.60. https://pastebin.ubuntu.com/p/QkdV2T66hq/ Link to comment Share on other sites More sharing options...
