Pre-launch disassembling

[Hadza]

Hello, fellows!

I'm not sure where should I put this topic, but I've REALLY wanted to ask how to avoid the annoying pre-launch disassembling. Parts just randomly start to go crazy no matter how much struts I add to them (lol) when physics kick in on the launchpad. I've found quite a nice solution to it:

Adding a "pump" to slowly load fuel into rocket tanks seems to work quite fine, but is a bit time consuming. I've never really tried making oversized rockets, but it works just fine with the medium ones. Just push alt+rightclick on both of the tanks and load fuel from the static ones, also requires to empty tanks before flight. Hopefully this helps

Launch clamps have always solved the "Dancing Rocket" issue for me.

Especially placing clamps higher up on the rocket (Sometimes I need to add girders to the the sides of the rocket so the clamps can reach without clipping through lower parts).

I also tend to build "down", meaning that if I have radially mounted tanks/engines on higher stages, I place in-line decouplers on the bottom and add tanks and engines directly below them to improve support. I can see you've got unsupported upper stage engines in this design, so building down from the those may lend some stability to your design, as well.

Hope that helps.

How high is that rocket? If physics kick in and it starts jiggling a little, it might simply break under the weight of the unsuported lower part. Add some clamps to the solid boosters
