FAQs
What is the best upgrade for the Mojave 6S?
For a single best upgrade, look into a high torque metal gear steering servo like the Savox SW-0250MG. Fast precision steering benefits nearly all forms of RC driving.
Does gearing change the top speed?
Yes, going to a larger pinion gear relative to the spur gear effectively lowers final drive ratio. This increases top speed at the cost of some acceleration. Ensure temps remain in check.
How much power can the Mojave 6S drivetrain handle?
The stock Mojave can reliably handle up to 8S power levels and 4000+ KV brushless systems with minor upgrades. For extreme power like 8-10S, consider beefed up driveshafts, differentials, and bearings.
What tires will make the Mojave faster?
Check out Pro-Line’s performance tire lineups. Options like the Fusion DS stadium truck tires offer much more grip for acceleration and cornering than stock tires. Tire selection depends on the surface.
Is an aluminum chassis better than plastic?
Aluminum chassis like the Hot Racing upgrade provide more precise flex-free handling at the cost of reduced crash protection. Great for racing and high grip tracks but may bend easier crashing. Hybrid plastic/aluminum chassis offer a balance.
Conclusion
The Arrma Mojave 6S BLX is an incredible RC right out of the box. But upgrades allow tuning the truck for your specific driving needs and style. Faster steering, more robust chassis, sticky tires, durable drivelines, and power system upgrades quickly take the Mojave to the next level.
Carefully research parts compatibility and suitability for your preferences like racing, bashing, or a blend. While it can get expensive, upgrading incrementally yields a truly custom RC beast built for you. The only limit is your imagination and budget!
