No reason why it would not work in the TT-01R. The 4600 motor would be great for drifting...but you would NOT need to increase your cell count to 8. I am running 6 and it is fast enough for drifting.
The mamba max motor dropped right into the stock TC4 motor mount.
As far as upgrade, I think you have most of them..just upgrade as you break stuff.
URC
yeah i think the 4600 set up would be great for drifting and if i ran an 8cell pack would rip it speed wise. what do you guys think
i just dont wanna put the BL set up and have to replaces gears and difs every run
