Oh sweet jesus, gimbaled engines would be fantastic. I also tried to edit the thrust vectoring for the boosters/main engine, but it didn't have the right effect (that, and I really have no clue about how that parameter works). I also saw the placeholder parameter for engine gimbaling and assumed that was tied to the thrust vector parameter somehow. Also tried to place a dummy OV on the other side of the main fuel tank for weight symmetry, but the thing is still unstable. Also, no amount of SAS modules will help this bird. To show you how bad this thing launches, I'll attach it at the end if anyone wants to give it a go. And that is what I've been trying to do. It's a very precarious balance. Made it to 10K by pure luck at one point (and never again). Separated the SRB's, and from there, was able to nudge it a bit higher with the main 4 cluster engine and OV engine. The split second I over-corrected, things went side ways in a hurry. Jettisoning the main fuel tank went beautifully though. For now, might make a beefed-up cheater SAS module that could maybe handle the force. Maybe this would make throttle steering a bit easier perhaps? If you knew how bad this thing flies, wings are the least of the worries right now . I've also built a clean config version with only the necessities, which still flies just as bad. Going to work with getting this clean version stabilized first, then will add on the adornments. Anyways, good stuff, thank you all for providing some input.
