Any word on those combined motors and gear boxes you had coming in on the slow boat 
from China?

Nice work on your tank.  My only comment is that you will need to keep
those geared well greased.  You should think about building some sort of
shield around your gears to keep grease from flinging everywhere.

When My dad and I were looking for motors, we ended up getting two 24
volt NPC motors and the gear boxes that went with them.  I made an
aluminum housing so the motors are on top of each other.  The motors go
through a reduction with the gear box and then go through another
reduction with a single step chain drive.  I got rid of the V-belts
because my tank required to much torque to use them.  My tracks
compensated for the V-belts because they are the intralox conveyor belts
with the smooth surface.  If the tank gets stuck, the tracks free spin
on the ground.  It turns great and runs fast for a heavy tank.  I used a
10 tooth #35 roller chain sprocket.  The chain ran to a 32 tooth
sprocket from small parts catalogue.  
In the pictures I removed the logic coil battery because I am working on
a turret servo which is powered off of it.  I have also removed the
receiver and receiver battery.  The black marks on the tracks are slices
of 3M tape that are used for traction on steps so people don't slip and
