I think the most important thing is to have a battery capable of discharging enough current to overcome the initial launch. To that end, the 40C TP packs have proven exceptional (that's all I use for the most part, save for a couple of 50C 2S packs). Also, I use "high start power" as a default (less if the track is slick), which again require good batteries.

Also, tire prep is important. You need to use some Koford, or similar, traction compound which serves two functions at the same time. It lets the car stick to the track on launch and its viscosity lets the tires slip a little, which helps helps the motor "power through" the launch. If you don't put enough of it, the car can stick to the VHT on the track and not move/stutter.

Even through all this, the car sometimes does the "Mamba Shuffle" simply because. For me that happens less than 5% of the time I think.
