Ani_27166343 Posted August 6, 2022 Share Posted August 6, 2022 All my rockets designs are very unstable during performing rolls Have no idea why they are fairly stable pitch and yaw Link to comment Share on other sites More sharing options...
jimmymcgoochie Posted August 6, 2022 Share Posted August 6, 2022 Sounds like a problem of having too much control authority. The roll axis is usually the easiest of the three (pitch, yaw, roll) to rotate around and if you have several engines which can all gimbal to exert roll control and/or lots of reaction wheels, they can easily set up an oscillation where the SAS keeps over-correcting. You can disable the roll axis in engine gimbals and reaction wheels (may or may not require advanced tweakables to be switched on, but advanced tweakables is definitely worth turning on regardless- main menu settings > enable advanced tweakables) to try and counteract this. If you want more specific advice or if you're getting a different problem, screenshots of the rocket(s) and/or a video of the problem will be needed.

DeadJohn Posted August 8, 2022 Share Posted August 8, 2022 What do you mean by "unstable during performing rolls"? Do you mean that pressing the Q or E key to manually roll makes the rocket unstable, with flips or other wild maneuvers? Or do you mean that your rockets slowly drift around the roll axis during ascent, so that the navball rotates? Link to comment Share on other sites More sharing options...
Ani_27166343 Posted August 9, 2022 Author Share Posted August 9, 2022 2nd one When ascending my rocket start rolling automatically and don't wanna recover from roll Link to comment Share on other sites More sharing options...
