To handle the power and speed of the Castle Creations 2028-780KV motor in something the size and weight of the Baja 5B Flux, Castle came up with the Mamba XL2 speed controller - able to handle up to 8S LiPo (29.6 volts) and fitted with a huge fan to keep things on the cool side.

If you want to go fast these days, you need to go brushless. If you want to go CRAZY FAST, you need to fit the Castle Creations 2028 motor! This massive powerplant features 780KV of power - that's many times the torque of the motors used in our Sprint 2 Flux cars! You need a powerful motor to haul nearly 10 kilos of large-scale buggy through mud and sand, and this is precisely the motor for the job! With extra-thick wires, gold-plated connectors and cooling fins, the 2028 is the perfect match for the Baja 5B Flux.

The 5B FLUX features a tool less easy entry large sized battery box capable of holding two hard case 4s LiPo packs or one 8s LiPo pack with an easy to reach opening for connecting the battery(s) and ESC together.

Unique in the world of large-scale racing, the HPI Viscous Torque Differential gets the power to the rear wheels as smooth as silk. It's easy to tune with optional diff oils and is fully fitted with hardened metal gears and an alloy case.

From the input shaft and idler gear to the alloy-encased differential, every gear inside the sturdy Baja 5SC transmission is made from long-life alloy to keep your truck running all day long with minimal maintenance.

The awesome Baja suspension really comes into its own with long-stroke VVC/HD shock absorbers and high-sidewall truck tyres, letting the tyres do their business whether you're driving over rutted-out whoops or flying over a big tabletop!

VVC/HD shocks deliver improved handling over rough terrain and feature large 6mm diameter shock shafts for increased durability. Threaded shock bodies are used for easy adjustment of ride height.

The high-torque SFL-11MG servo features extra tough all metal gears for durability, an aluminum steering arm and a water resistant case.
