Brody.mack Posted January 14 Share Posted January 14 I'm still new to KSP (~50 hours) and I am planning a large mission to Duna with an orbitally assembled (through docking) spacecraft that has everything I need for a tour of all Duna SOI. However, I am having trouble designing a stable craft. When I tried to assemble it the components were too unstable to dock and after further testing via the cheat menu, when the entire craft was docked and in orbit, it still had stability issues. I most recently tried to add Vernier thrusters to it, but it mostly has the same issues. Any tips? Quote Link to comment Share on other sites More sharing options...
18Watt Posted January 14 Share Posted January 14 Can you describe what you mean by 'stability issues'? Quote Link to comment Share on other sites More sharing options...
Brody.mack Posted January 14 Author Share Posted January 14 It's either over-reactive to SAS changes and can't settle on an orientation or doesn't have enough RCS control. Quote Link to comment Share on other sites More sharing options...
Vanamonde Posted January 14 Share Posted January 14 You could try using more reaction wheel parts. Quote Link to comment Share on other sites More sharing options...
ArmchairGravy Posted January 31 Share Posted January 31 My tips for large ships: As few parts as possible Pull with the thrust rather than push Large docking ports only for thrust-bearing couplings Reaction wheels active only on main body Disable RCS on parts docked to main body Low thrust Struts to stabilize main body Getting the main body correct is the key to larger ships. Your vessel should not need RCS to turn when assembled. It will be way more delicate due to the couplers, so slowly ramp up the thrust. I initially turn my thrust limiters down so I don't put too much strain on the couplers. Then I save and experiment to find out how hard I can push it. Finally, assembled craft are more stable if they're pulling rather than pushing. Put the drive engines at the top and have them pull the rest of the craft along.
