The Navaronne Gun, Flak88, Comet and Tiger all use 6 RPM turret rotates, 
which provides excellent accuracy for long range shooting. Tanks that 
battle at close range with high-speed passes like the Cromwell and T-34 
use faster rotates, probably 2-3 times faster.  However, at those 
rotational speeds, a proportional speed control is necessary in order to 
  control it properly.  I suggest starting with a slower rotate (since 
you'll be battling at longer ranges initially) and then adjust over time 
if necessary.
