Losi is not helping much either, in the Excelorin combo manual they say you should use a 14t Pinion with a 45T spur on 4s in a buggy using the 2400kv motor. In the 8ight-E manual they say you should use a 13T and finally the conversion kit comes with a 15 and 16T pinion (but with no recommendations on what to use). Kind of confusing. I think I will go back to the 13T just to be on the safe side.
