How are you going to spin the turret, friction or chain drive?  Where are you 
planning on putting the motor, in the turret or in the hull?  What size friction 
wheel or drive sprockets can you accommodate?  How fast do you want to spin it?  
These are some of the questions that should be answered before deciding on a motor.

Some points to remember when deciding on a turret drive.  A friction system will 
give when something impedes rotation (i.e. a tree or another tank).  A chain drive 
will not but will be more reliable if the spin mechanism gets gunked up with 
paintball goo (which will happen).  If you have a long barrel overhang a friction 
drive is worth serious consideration.
