MechJeb Overcontrol Issue #700

Closed xATHEISTxDEITYx closed 8 years ago

xATHEISTxDEITYx commented 8 years ago

Currently been designing and experimenting with SSTO spaceplanes, but anytime I use Smart A.S.S. or any other Mechjeb Maneuvering system, I have a severe overcontrol issue to the point it will overcorrect into chaos. Stock SAS seems to behave normally and correctly, without overcontrol. Setting nodes with MechJeb, then using Stock SAS to align also has no overcontrol issues. I have made sure that Smart RCS is not in overdrive, and all other control functions are at standard values. Overcontrol issue is apparent when using RCS and using torsion attitude controllers.

You could try my PID settings if you want, I build pretty much only bigger rockets and it works good enough for me, if I give it some control surfaces as help atleast.

Thanks, but the tweaks you suggested had no notable effect on the overcontrol issue. I have removed Tweakable Everything. I have a feeling that may be screwing with the mechjeb calculations.

My feelings were validated. Tweakable Everything was causing some sort of issue with MechJeb. If anyone knows why or how, I'd love to know. Otherwise, this issue has been resolved
