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 ,,

another veiw

Cogging is more noticable when overgeared because more very low-end torque is needed. I have found this to be especially true with a Warrior 9918 (9920), but not so much with the MGM controllers. BTW, great setup!

im runnig shulze 18.97 .. also noticed i had timing set to .. softest of soft !! . pic of new 40 series alloys and see old mounting setup

and another quick questions ,, should i keep the centre diff , open , torsen or lock the centre diff??

you can play with silicone oil..

from 20K till 300K will do the trick..
