Getting SMALLER spur for the TA05R is not a problem at all, so 100T or smaller on TA05R is not a problem (with hugh pinion..)
I had the opposite problem by using 4.5R motor...the biggest I can use is 108 and I have to use 22T pinion...but at the end, realized 4.5R is just too fast for local track...
