Vector X12's are very good, depending on which turn you buy. I run the 17.5T for stock class, but for drift, it may not have enough oomph. I'd go 12T or 10T.

As far as ESC's, Castle's Mamba Max Pro works well, has all the adjustments one would want, and unlike other Castle ESC's, is sensored, so you can use the Vector X12.
The MMP's hold up rather well, and take a lot of abuse. Gear low, so you will not have the overheat problem.

The MMPis the lowest cost ESC that will take the punishment. Ihave 7 (now 8) Castle systems, and none have failed, two of which were mercilessly abused, and are more than five years old, and STILLgoing!

There are others, of course, but the decision is yours, ultimately, so it's up to you, but Castle has always had my back, and never failed me. Can't say that about Novak or Traxxas. Tekins are great, if not a bit pricey, but will fit the DRB (not much room on that chassis) well. Associated also has a drift system, the Ultimo Drift Combo, or something like that, that will work well.
