Need info on track drive motors
Hi, I am starting a scratch build of a Cat 330b 1:14 scale, I am ready to order track drive motors, I have no idea what size, make etc. to purchase, I have been looking on the Pololu site. I want geared motors to keep the speed down to be scale looking. Any help or suggestions would be a big help.
Thanks Terry |

Do you have any idea what the overall wieght will be of the model ,will it be built from all steel.Would give us a idea of how much torque you will need.I would say the most torque you can get from a 12volt gearmotor. Here's one from robotmarket place for example ,its showing 370 oz of torque at 12 volts . http://www.robotmarketplace.com/products/0-B231.html

Re: Need info on track drive motors
The ones I use in my 1/10th scale stuff are 17rpm and 277oz in torque. I think they might be a little large looking for your scale(540 motor)but they have plenty of power in my cat 955 and it is 20lbs. I get them from the robot shop.

Re: Need info on track drive motors
Thanks for the replies, I expect it will be fairly heavy, but I can't even guess at this stage, it will be built from steel. I am looking at one on servocity, 20 rpm with 375 oz in. That seems to be close to what r/c logger used on his excavator.
