Trf501x ball diff
Is there any reason I shouldn't put the diff balls in the inside holes cause the diff balls are on the very edge of the diff plate anyone tried the inside before ?cheers chris

do a search on diffs on the Tamiya forum. Several people have stated (me included) that if you buy more balls for the diff and add to the inner holes (so all diff holes are filled inner and outer) you will make a smoother diff and also improve the efficiency so less rebuilds.
Jimmy did state somewhere why you shouldnt use the inner hole but nothing relating to why you shouldnt use both.

Ok now I see where your coming from and yes I forgot about that - sorry. I found that as the diff screw in the 501 was so thin that I had the same funny feeling on the diffs when I added the balls so I ended up adding a kyosho screw, thrust race and nut and that resolved the weird feeling, but then again my car was a bit weird so could have been a one off badly made item. kustom chris Still after looking up diff info today every one is saying here the standard diff setup as per the manual seems to work fine as it is.

I ran it with the extra balls and it felt about the same too me, seemed to last a little bit longer. I run with overdrive and the front diff which has 8 center holes and 8 outer holes (manual indicates to use the outers) works even better when loaded up with diff balls. Extremely smooth and didnt slip.

it alters the loading on the balls, the inner balls will have a larger loading than the outer balls, so you end up setting the diff according to the inner balls (slightly tighter), the use of the outer holes make for a smoother diff action.
