What you can skip
- Speed-run gearing: this is a monster truck, not a speed car.
- Aluminum everything: Traxxas plastic flexes where aluminum bends.
- A single larger charger channel: dual is what saves time.
What to upgrade first
- A second pair of packs if you want more than one run per charge cycle.
- Tires once the stock ones wear, because this truck eats them.

Frequently asked questions
What does the expert basher build cost in total?
The expert basher build on this page comes to under $2,500, the budget in the table: catalog prices for every item, summed with quantities and rounded up. Prices change often, so the buttons show Amazon's current price. Nothing on the list is optional to get running except the items we mark as upgrades; the "what you can skip" section names the things people commonly buy too early.
Do I need a LiPo charger for a basher?
If the car ships with a USB or wall charger, it works, but it is slow: often two to four hours per pack. A balance charger at 1C charges a typical 5000mAh pack in about an hour and lets you run LiPo packs safely. It is the most useful upgrade after a second battery.
Who should not buy the expert basher build?
Beginners, small yards and anyone who will run it near people. At this size and power a crash can break bones. It is also expensive to feed: two packs per run, and parts cost more than 1/10.
