Another 4wd articulated tractor

[mazdaparts]

Got some more work done on the tractor. I found out there is not any foams in the tires. I added some bb's to the tires just to see what happens. Turns out 15oz. in each tire is too much for the steering servo in its current setup. It took the tractor minus the body to just over 6lbs. So I took the bb's out and installed the body. With the body it is almost 7lbs. The servo is still not happy. It turns while moving. It could be the servo it is old and possibly wore out. I have a newer one that I will be trying. Here are some pics with the body mounted and a pic with the proud owner of the tractor.
