  You really need to play a game of vector.  Turning radii(?) are caused
by
the interaction of a plane and air or a ship and water.  In space there
is
no such drag.  If you haven't done vector addition or need a refresher
try:

The real problem is advanced drives lose much of their advantage in
vector.
Spinning on an axis in space takes an insignificant amount of time
compared
to turn length so not needing to spin isn't much of an advantage.

Anyone know of a web based game of Asteroids?
