The ARA-2091 is Arrma's 35mm motor cooling fan set, supplied complete with a fan cover and mounting screws. It attaches directly to the motor heatsink to pull heat away under sustained running, and fits across most of the 223S line as well as the brushed MEGA models — eight vehicles in total, spanning 1/10 and 1/8 scale.

Heat is what limits a motor over a long session rather than any single hard run. As temperature climbs the motor loses power and its bearings and magnets wear faster, and on a warm Australian afternoon that point arrives sooner than most owners expect. A fan doesn't change gearing or power output, it just buys you more running before the truck needs to sit and cool.

The included cover is worth having rather than an afterthought — an unguarded fan sitting low in the chassis picks up stones and grit, and a blade strike at speed usually ends the fan.
