The Centurion 2069 ship I imported into Orbiter is set up for 'ion drive'
engines. Capable of velocities well over 250Kps. Atmospheric flight is
obtained by conventional airfoil wings, control surfaces and rudders.
However, I have to mount much smaller engines for slower flight speeds,
since the primary engines put out way too much thrust to control landings
very well, even in Earth's gravity and atmosphere, extremely difficult to
control when landing on the Moon or other low gravity/atmosphere
planet/moon.

In this configuration, going to Brighton Beach Moon base from Cape Canaveral
takes about an hour or so at 120Kps. Slowing down is not a problem, OI is
not a problem. Next test is to fly from Brighton Beach to Olympus, Mars, at
a test speed of 200Kps.

Ok, so it isnt following real world scenarios. But, all things advance. NASA
has re-opened the space nuclear power research and soon we could see either
the shuttles or shuttle replacements powered by nuclear reactors, which in
turn provides plenty of juice for HV ion drive engines.

I do have one inquery. Is there a way to have such a high velocity ship have
retro thrusters that automatically adjust their density output based on
velocity, and adjust themselves as the velocity changes? Can this be applied
to the retro, pitch, bank and yaw thrusters as well? Will the engine in the
sim run such engines in this manner?
