Currently, a very light shuttle (usually salvage shittle) can move faster with thrusters than by doing FTL jumps
My suggestion is to make FTL jump have longer reach if the shuttle is small enough
Powergame issues with this, is that a 3x1 shuttle that is just console, thruster and gyro would probably have very long range, so, to balance it out, I suggest having a cap on the range of 2x the radius of what the current range is, and minimum range to stay the same.
