gear ratio's direct drive emaxx tranny

[sly118]

ok just took it for test run .. no pinions to choose from so i used the one off the top shaft on the stock emaxx gearbox ( seems to be the same pitch , 13tooth)
so with 46 spur and 13 t , i drove it , its way too tall , as suspected , , one thing i noticed , cogging is a fair bit more noticeable, but cleaning up the gear ratio might help and little ,
ill probly have to go 51 spur 10t pinion , time to do a order with mike ,,
