Hi Tyng,

I could go either way with the motor, in the hull or in the turret (I've got
lots of room)
and I haven't decided yet on friction or chain drive, but since everything
in the turret
is self-contained I could just put the motor shaft in the middle of the
turret, either
in the turret or in the hull. The turret will be totally enclosed and sealed
from the hull
since I'm aiming for a serious watertight design. What kind of RPM motors
are you

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.
