I know you guys are probably saying this thread is like "The Boy Who Cried Dozer".
I refit the dozer AGAIN this time with full sized HiTec 645MG servos. They should be much more reliable and the lower RPM and higher torque from previous mini servos make the control MUCH better.
I still need to figure out how to keep the track pins from wandering out. And I may have to come up with an adjustable servo tray so I can adjust the track tension. So far it seems to work great!
