Liljohn nailed it ...setting GEAR MESH is my biggest reason for chosing over the other
The larger tooth 48p can be off a little on the mesh and NOT strip a gear.
The finer 64p gears, the mesh is crucial. Too tight, gear binding occurs, too loose, gears wear or strip really easy.
So depending on what type of vehicle I'm using, I'll run one or the other (I have a large stock of BOTH)
For instance in my TC3 Touring Cars, I run 48p, because adjusting the motor is sometimes difficult to move the motor just a small amount.
In my old HPI Pro2 TC, adjustment is easy, so I use nothing but 64p.
OVAL cars also easy, so nothing but 64p.
