Mod.4 Steel Pinion Gears
These are Pinion Gears for certain models that use the Mod .4 Pitch
Currently I have 2.0mm Shaft gears which will fit motors such as 130 size and 180 Brushed motors, And some Brushless motors such as the Mofo Rc BAM Motor or others with a 2.0mm shaft diameter. When i get other mod.4 gears with different shaft sizes or gear teeth count i will add them here.
The stock trx4-m gear is the 2.0mm mod.4 11T This is also the gear that will fit the mofo rc Big Block motor and BAM motor for the trx4-m use
These pinion gears are hardend steel and are Press on gears, They do not have set screws. When installing press against the back of the motor case either where the shaft protrudes or where the shaft would protrude out otherwise motor damage can occur.
