Triple Omega

This thing is insane as a final stage! Just got it up to a few hundred K before lighting it and it ended up at 4400 K and 8458 m/s before the final decouple.(with 1 fuel tank) I'll try to get it up there with more tanks, or maybe two stages or double engines. EDIT: Just made 12863 m/s and 10800K before the final decouple with two fuel tanks. Also, I'm now at 12861.7 m/s and not decelerating anymore.

I just tried to make the same 9 engine setup as in the OP's pic(without the 3 decouplers), but with liquid enigines. Unfortunately there seems to be a bug as the parts just rip themselves apart at seemingly random times. Even turning the engines completely off doesn't stop it, so I assume it's a collision problem.

I haven't had the chance to post a single thing because of this. I discovered KSP a few days ago and every time I got on here to post something a new update was out, so my comment was already outdated. ;P
