Does anyone know of any larger spur gear options for the TRX-4 with the two-speed trans?
It has the 45T spur at the moment, which is the largest one Traxxas recommends/sells.
I can always do the underdrive diffs, which gives me about 13% reduction (3.09:1 -> 3.5:1).
I've tried smaller 9T pinions but, when they get small, they just start howling.
Looking at the manual, and a little math, the Total Teeth Count (TTC) is between 54 and 61.
So in theory I could us a something like a 52T spur and a 9-12T pinon; however, I have no idea if it will fit in the trans case?
