HobbyStar Affront 4268 4-Pole Brushless Sensored Motor For Off-Road 1/8 Scale
The HobbyStar Affront 4268 is for 1/8 off-road buggies that need smooth sensored throttle control without jumping to a longer, heavier can. It is a 4-pole sensored brushless motor in a 68.7mm 4268-size case, with 1900KV, 2100KV, 2350KV, 2600KV, and 2800KV options and a 2400W rating.
The useful bits are all the usual things racers and serious builders actually care about: adjustable timing, a removable/replaceable rotor, 0.2mm stator laminations, high-temperature copper windings, oversized high-speed bearings, and a CNC 6061 T6 aluminum heat-dissipation shell. In plain English, it is built to run efficiently and stay tunable, not merely to look dramatic in the parts bin.
The off-road version uses a sealed can design with splashproof and dustproof protection for normal dirt-track and dusty RC use. It also gives you M3 and M4 mounting holes, a 5mm shaft, and a compact 320g weight. Match the KV to your battery, ESC, gearing, vehicle weight, and class rules; high KV plus optimism is still not a cooling system.
