Hpi has 2 gears for the upper shaft inside the gear box ,one is a 19 tooth for truck and one 20 tooth for buggy. How do these work together when they both share the same idler and diff gear and case housing? Is there any mesh problems ? I would like to put the 19 tooth in my king buggy to give it more snap on the bottom end without changing the pinon and spur.
gear swap?
