Wild Thumper Motor Issue
March 31, 2013
Continuing my fun with my Wild Thumper (yay!) I've been tracking down an issue where to get the right set of motors turning I need to issue much higher PWM values than the left side. For example on a charged 7.2v battery a PWM of 80 will turn the left side motors (unloaded, up on a block) but 100 or more is requred for the right side motors to turn.
I disconnected each of the right side motors and have found that one of the motors seems to be the culprit. That motor needs a higher PWM before it gets out of stall and the current drops to only slightly higher than expected levels.
1. Is this a normal problem people see with these motors?
2. Are there hardward or software workarounds?
Anyone have a picture of how to properly mount the Controller in one of the lower chassis slots? Just having it sit there seems a bit hacky.
