USI-LS is easy enough. I need to switch out using a structural tube because, I think, it is from Making History. I'll upload a new one sometime tonight.

Craft File Mod List Be gentle. I'm sure my rocket design sucks on so many levels.

I'll try to figure out the mod set that makes the rocket work tonight. I don't think it's going to be very long. Mostly your mods amusingly enough.

Dumping the gimbals to 30% of max helps some but the craft still attempts to correct itself. I've also started burning my fuel from top down with LH2/O rather than bottom up like I do with LF/O and that seems to keep the CoM more balanced but SAS still wigs out sometimes.

It's more I would like to play the mod as designed instead of changing it to deal with my short comings. Hence why my original post was asking for design tips, not demanding the author fix my issue. The different weight considerations is a challenge I would like to overcome. If people aren't having the wobble I am seeing, then something I am doing is wrong and that is what I would rather fix.

No engine plates on any of them. All of them are direct mounted to the 1.25/2.5m parts. Perhaps I'm just used to the gimbal from the stock engines. I did a LF/O lifter with a Mainsail and 2 boosters with 3x Otters from one of the NF (I think?) mods and they behaved fine. Is the gimbal setting only for your cryo engines or do is it set that way in the NF mods also? I didn't really have any issues with the Otters causing problems with SAS. Of course they could have just been completely overshadowed by the Mainsail. Is there an alternative to changing the mod to calm down SAS issues? I know there used to be mods, but most of them seem abandoned. Would MechJeb Smart A.S.S. help at all?

Main stage is Fuji, boosters are Vesuvius. Vacuum stage is Ulysses. All of them introduce a wobble. The Ulysses is super noticeable because it loses it mind when I make minor adjustments during a maneuver. Even with the gimbal range set to 30-40% things still go crazy. I've never had to limit the gimbal on things like the Terrier and Poodle. As far as I can see autostrut is grandparent for almost anything that needs struts. I also have Kerbal Joint Reinforcement installed, so I'm not sure what else I can do to fix noodle rocket.

Really enjoying the mod so far. It definitely adds some neat new considerations that stock engines do not. However, I am having a hard time with design using the engines and associated fuels. When I build lifters using the stock LF/O engines they are super stable. When I use the cryo engines and LH2/O I seem to always get insane SAS wobble. My rockets are indeed longer to accommodate the extra fuel requirements however they aren't any longer than anything I have made using stock LF/O parts. Are there extra design considerations I need to be aware of when using the cryo engines and fuels? I'm at a loss so I figured I might get some advice from people who have been using it longer than I have. Thanks!
