I just did. One tweakscaled jet fuel tank and a 1.25 nuke engine. Trying to fight a wobble? Try using just one tank then the engine. So Tank-Engine-Whatever
Not really, as you can see, the rover will be landing on the tanks. Also, building an efficient nuclear tug is hard, but I've managed to come up with one.
The launch was jittery... less said the better. Nontheless, Val made orbit, and posed for the cam. Pics of launch aren't shown, but can be proved later down the line if needed.
