My personal experience with FAR is that ever since installing it, my rockets have been insanely easy to design because it is simply intuitive for me to design something aerodynamic. To solve your problems, consider the following: 1. Shaking/Rotating Radial Decouplers - This was a common problem I encountered when using a lot of Solid Fuel Boosters, regardless of RT-10 or BACC or any other model. A high thrust to weight ratio results in those joints shaking and you usually need 1, 2 or 3 strut per booster (RT-10, BACC, S1 SRB KD25k respectively) to secure to the main rocket you're boosting up. 2. Centre of boost significantly below top heavy designs. If your rocket has a huge amount of mass towards the top and very powerful boost towards the bottom, your rocket will become unstable immediately upon launch/stage activation. 3. Over compensation by RCS + SAS combination. Sometimes I completely disable RCS during launch and build in more SAS controls. RCS tends to over compensate and results in small twitchy movement. It continues to try to compensate that twitchy movement and you get even more twitch before it breaks apart. This is really a compounding effect of a rocket that has many parts and has weak joints/linkages or radial decouplers etc. 4. Weak structural joints/linkage - Certain joints in the rockets are weak. Often this occurs in large multi-stage rockets where the sections for orbit or interstellar travel starts shaking because it has a significant amount of mass and the joints are stressed. Placing struts as suggested will help this issue but you have to identify which parts are the one which are disconnecting etc. My advice in general is plan your mission top down. a. Bring only what is absolutely needed at your final point (e.g. Science Lab? Goo? Thermometer? etc. ONLY BARE MINIMUM). Fit the smallest possible engine and fuel. b. Build a redundancy of 10-25% (depending on your competence) to account for human/piloting error throughout your stages working backwards from your final stage. c. Use Solid Fuel Boosters in the early stages as much as possible. I found that S1 SRB KD25k great for lifting things into higher atmosphere and using RT-10 to assist in achieving stable orbit. If you follow that advice your rocket will be really paired down and have less moving/shaking parts.

What is the most efficient cost in total to launch 1 Orange Tank into Space? After putting in a few extra functions of propellant, lights (so u can see when u dock), batteries, solar cells... They generally end up being about 87k and may vary from 80k - 90k depending. I can shave it down to 70k by paring it down to purely fuel but I think having the additional functions are better. EDIT: Hangar Cost is 86,204. After removing Decouplers, Boosters and all Fuel and Oxidizer, it is 44,418 so net transport costs are about 42,000 +/-. I like to decrease that figure as much as possible. This is purely a ballpark figure estimate in launch hangar, it's not a final net of recovery cost estimate. Please share if you have any designs that save significantly by costing below 80k, providing functions of refueling, battery and recovery after fuel is used. I have attached my current design to date with FAR mod.

Put multiple BACC Solid fuel boosters together? You can also reduce cost and increase efficiency by mixing it with the cheaper initial booster the "RT-10 Solid Fuel Booster" which provides really good thrust to weight ratio. You should type out the conditions clearly word for word. I don't think you quite understood the conditions as a contract I had for the BACC solid fuel booster required me to test it at altitude of above 22,800m and at speeds of >500*m/s which made it really difficult.
