I have three MSTs
MS-01D Pro VIP
FS-01D Pro VIP
XXX-01d Pro VIP
All three are great.
The rtr is a great out of the box car.
I would upgrade all the uprights to aluminum, all the turnbuckles to left/right adjustable and get a one-way in it.
Also plan on a sensored brushless set up, 10.5t or 8.5t.
R2 hobbies HPI T-drift knock-offs for the street, cuz they're really cheap and wear just as fast as the HPIs.
Also get a fast servo, Bluebirds are cheap so buy a couple.
When you go drift, chalk out a track and practice.
Just free drifting doesn't teach you much, once you're confined to a track layout you really start learning how to control it.
