RC drivers, listen up! Does your motor get crazy hot after a few runs? Yeah, we've all been there. This little aluminum cooling fan is a game-changer. It's a 30mm fan that spins at a whopping 28,000 RPM to blow cool air over your 540 or 550 size brushless motor. That means less overheating, more consistent power, and longer motor life – which is exactly what you want when you're bashing or racing. It's made from lightweight aluminum, so it won't add much weight, and it dissipates heat way better than plastic. The fan runs on 5V to 8.4V, so you can power it straight from your receiver. Comes with about 18cm of wire, so routing it is pretty easy. It's designed to fit 1/8, 1/10, and 1/12 scale RC cars – think brands like HPI, HSP, Tamiya, and similar. You can choose between red, golden, or silvery finish to match your ride's vibe. Installation is straightforward; just screw it onto your motor's heatsink. One fan comes in the package. A must-have upgrade if you run your rig hard. Keep it cool, keep it fast!
