pinion size using 65t spur
 

hey guys can someone enlightens me on this, i have 65t spur 32pitch how many tooth of pinion to be use by the way im using 6.5hv pro brushless system, 12 and 14 cell stock tires tnx...

What vehicle are you running? And what tires?

new emaxx 16.8v
 

sorry i forgot to indicate that this for the new emaxx...

i thought the new emaxx used mod 1 pinions since it has a revo slipper on it.

or im i wrong

yes it has the same revo slipper just like the new e-revo but the spur gear pitch is 32 just like the other epmt.

I would say to go to the speed caculator:

Punch in the numbers and try for around ~35mph to start with.
