Hallo everybod,
The FF03 gear diff is too wide on the diff case to fit a regular 201 gear case

.
Thatīs why Iīm also thrilled Tamiya brings another gear diff, different shape...
Why-o-why donīt they use the FF03 gear diff in the TA-06 ?
Because they want to help the 201ers, too !

And sell some more
And Iīd happily buy some for high grip carpet- I get weary of checking and rechecking and doing "8th-of-a-turns" every 2-3 packs..
