WIERD STRUT FUNCTION, OR MALFUNCTION

[qbert]

No mater how many struts I put on my spacecraft I can not stiffen the boosters and it's causing a wobble in flight, is anyone else having this problem.

Try using fewer struts, not more. More struts means more joints and too many joints cause the physics simulation problems.

For a booster, just go with one or two struts. One on the top and optionally, one on the bottom. At the point closest to whatever you're connecting to.

Also, if you aren't using autostrutting, consider trying that. It has to be enabled in one of the main menus and after it's enabled, you will find an option to turn on a part's autostrutting in its right click menu.

Also also, I notice you are using KWR and someone in the KWR thread mentioned having wobbling with the medium and heavy KWR struts. If those are the struts you are using try replacing them with stock struts. (but also still use fewer struts)
