Control difficulties in space

[Misaka]

Heya!

I downloaded the Kethane addon a few days ago and decided to give it a go by setting up a proper mining operation far far from Kerbal.

My first two ships were just probes to start scanning for places, but my third ship has been giving me serious headaches. I've built a very large 'tanker' ship to hold large amounts of Kethane, and act as a mobile space-station core for the other components, It took me awhile to get this into space, when I discovered it has a rather massive flaw, it's nearly uncontrollable in space. I am still rather new to the game, but I've read up on the basics of design and I can't really figure out why this ship isn't working right, I've posted a screenshot bellow. The CoM and CoT are aligned, but as soon as I throttle up in space the ship begins pitching harshly up or down.

Any ideas? :<

It's been a while since I've played with Kethane (Well, a week or 2. Since 0.22 came out) but I do not recognize one thing on that craft.

I do though notice you have a ton of engines and a single command pod. You may want to look into adding some reaction wheels to that bad boy, or RCS thrusters.

More control devices (RCS, reaction wheels), make sure you have adequate power generation for the reaction wheels, and I'd like to warn that even when the CoM and CoT look aligned, in space even a seemingly negligible misalignment can result in spinning at high thrust.

Most of the parts are from the Lack Luster Labs stuff. It does have RCS and SAS systems on it too, I highlighted the RCS in red, and the wheels in green. It also does have tonnes of power, the 4 engines on the back are nuclear engines that generate way more than the ship itself really needs. But I'm going to have another look at the design when I get home to see if I actually added the right parts.

If I get this working or not, I'm going to start work on a base and some landing equipment, hopefully that goes smoother.

I got it into a Munar orbit~

I'm not entirely sure how I managed it, with all the wheels it handles like a glacier now, and I certainly didn't pack enough RCS fuel, but that's something I can solve with supply ships.

Are those placeall RCS ports?

Personally I'd use the normal ports, with 4 directions each
