Hot bodies 1/8 diffs

[RC-Monster Mike]

Even 50K in the center will allow wheelies at will, Mike - I can wheelie my truggy with 10K from a standing start on grass. 50k will allow some give while feeling largely like a locked diff. 300K is totally defeating the center diff - I don't think this is the root cause of the problem, though. The servo saver would be a primary candidate, along with linkages and bearings. A plastic rod end could be cracked but not broken, for instance - you wouldn't see the problem, but it would pull away/flex under stress when in use. A stuck bearing could also create the pull - there should be signs of this if it is the case(scars on the shaft it rides on, for instance). If you are using 1/8 diffs with diff outdrives, it could be as simple as a loose set screw on one of the drive cups(would send power to only one wheel and eventually diff out to the wheel not receiving power). The truck should accelerate nice and straight without the D-box.
