tmk2 Posted July 20, 2011 Share Posted July 20, 2011 Before I launch all of my dials (throttle, G meter, yaw, roll ect.) seem to alll go crazy and mid flight the ship becomes unstable any ideas why? Link to comment Share on other sites More sharing options...
tjrieves Posted July 20, 2011 Share Posted July 20, 2011 I'm not saying you're stupid, since I've done this, but you're not pressing random keys before launch, are you? Are you using the keyboard or a joystick / controller?Also, it may be because your rocket is not symmetrical, although that probably wouldn't make the dials go crazy.You might just have to download the game again. If so, save your parts and your ships folders in a back up folder, so when you re-download the game, you can have the same parts and ships.Hope I was of some help.

Kage Posted July 20, 2011 Share Posted July 20, 2011 If you have a massive ship, the gauges tend to go crazy before launch. After you toss a few stages, it becomes normal again.Hope that helps. Link to comment Share on other sites More sharing options...
Tim_Barrett Posted July 21, 2011 Share Posted July 21, 2011 Ok, try these:1. Unless its all boosters (you can't change the power of boosters), try starting the launch at a lower power, then slowly excelerate.2. If you have fins on, try putting them on the bottom of every stage that burns in the atmosphere. This will create little drag but enough to keep the rocket aligned.3. Add more SAS modules. Make sure they are activatred before launch4. IF all fails, try one last thing, you may be going too slow which makes it tip over, so try adding boosters.That's all I can say.

tjrieves Posted July 21, 2011 Share Posted July 21, 2011 Yeah, this problem could be a number of things. Honestly, it's like going to a doctor and complaining about pain but not giving the doctor any details. Link to comment Share on other sites More sharing options...
Millitron Posted July 21, 2011 Share Posted July 21, 2011 Also be very careful not to over-correct any drifting. Instabilities tend to compound. Link to comment Share on other sites More sharing options...
Xivios Posted July 22, 2011 Share Posted July 22, 2011 For that matter, don't use too many SAS modules. I've had scenario's where they would caused a sort of resonance and they would overcorrect so much that the ship got worse and worse every pass until eventually ripping itself apart. Also try to keep them near the centerline, they produce force at their location - on a rocket with 'legs', as many sort of do - they will bend and twist and this can compound the problem.

Tim_Barrett Posted July 22, 2011 Share Posted July 22, 2011 Guys, to fix 'overcorrecting' creating stability issues, when you have semi-stability, press caps lock to change you SAS/manual force to percise, then again to go back to instant.

It should (assuming the rocket is simply spinning around its vertical axis) stabilize the rotations.I often seem to build rockets that start spinning like a bullet coming off the launchpad, and I've found this works pretty well Link to comment Share on other sites More sharing options...
PulseNeon Posted July 23, 2011 Share Posted July 23, 2011 I've noticed that, any sort of radial decoupler SRBs tend to start swaying back and forth for me, hell, flat/wide rocket designs start 'flapping' and the entire rocket becomes rapidly unstable because of it, often until I jettison the rockets or they basically dealign the rocket severely.Only a single quad setup of these is stable for a -while-. Is it because they are on full burn?am I missing something? building them wrong? Link to comment Share on other sites More sharing options...
Tim_Barrett Posted July 25, 2011 Share Posted July 25, 2011 I've stopped 'flapping' by making inward winglets from the boosters that touch eachother, creating a sort of suspension between the boosters. Works for me. Link to comment Share on other sites More sharing options...
