Which way to put in the ball diffs?

[KyoshoK]

just wondering which way to put the ball diff inside the gear box so that the thruster screw does not unwind loose?

the instruction says put the rear diff in, with the screw on the battery side

and the front diff in, with the screw on the motor side.



now its possible to swap then the other way around... which one should i swap around?

i hope that makes sence
