I have a re-release top force that I am racing at our local club on astro turf. I've stripped the teeth off the rear outdrive and metal diff parts after about a dozen runs with it. I'm running a 13.5T brushless motor, so reasonably tame for today's standards, but obviously a reasonable amount of torque for the Top Force. I've been researching the TA03 ball diffs and was trying to find out if these come with the machined metal parts rather than the cast standard parts included with the kit? Do the splines on these machined parts hold up better than the kit ones, or am I best just using a less powerful motor if I want to race it regularly?
I've always been told never to let a ball diff slip, but I've read a few comments about people saying the ball diff allows some give in the transmission since there is no slipper clutch. Are we saying it can run slightly loose, at the detriment of quicker wear to the balls and plates, which would allow less strain on the metal drive parts?
