Steve:
To figure out how fast your tank will go:
take the diameter of your track drive sprocket and multiply by 3.14
and that gives you the distance the tank will move for each revolution
of the drive sprocket.
Track sprocket diameter(in inches) X 3.14 = inches the tank will
travel for each re

This is my first tank,so I am not an expert.
For goning in a straight line it should not take a big motor, but a
"pivot-in-place" type turn is another situation. A "Pivot-in-place"
turn is going to take a LOT of torque.
My setup will produce about 80 pounds of force at the track (without
Mark, thanks for the response. Since I am not sure about the torque,
let me see if you can answer my question. The unit I am building
Is projected to weigh in at around 175lbs. I only need to be
able to achieve a speed a little faster then walking. Do you
think that motor would be sufficient?

They have a 7 or 8 to 1 gearing built in.
550 RPM and 4.5 inch pounds of torque per amp.

I am going to be ready to test 2 tank chassis soon and would like
advice on amperage.
Both tanks will be at or under 50#. I am going to run them on
12volts.
1st tank will use KCM (direct drive), the other deWalt cordless drill
motors..
I can get D-cell NiMH with 10 - 12 AmpHours. Is that OK or a
Mark, what kind of motors are those in the pictures?
Thank You
