i’ve got one big missile and several smaller ones that feature fins. fins,
of course, help control direction in an atmosphere. but would they be useful
in space?
i ask because on my fighters i often use “wings” which i call stabilizers.
The idea is that having engines farther away from the central axis would
make the fighter more maneuverable and stable. “wings” also work well in
mounting

Placing the engines far from the central axis wouldn’t do anything, but
placing them far from the center of mass would give them some mechanical
advantage.

Placing the thrusters far from center of mass makes it easier to introduce
angluar momentum into the system; i.e., the missile cartwheels out of control.
Ideally, center of mass and point of thrust would be same point.
