Hey RC helicopter enthusiasts! If you're flying a Blade B450, B400, 330X, 330S, or any model that uses the BLH1655 part number, this tail drive gear and pulley assembly is exactly what you need for repairs. This is an official Blade part, so you know it's made to the right specifications and will fit perfectly. The gear and pulley work together to transfer power from the main rotor to the tail rotor, keeping your heli stable in flight. Installation is pretty straightforward if you've worked on helicopters before - just follow your manual's instructions for replacing the tail drive components. The quality is what you'd expect from Blade - precise molding, clean teeth on the gears, and everything lines up right. I've used these in several repairs and they've held up well through many flights. The part number BLH1655 makes it easy to confirm compatibility with your specific model. Whether you're replacing a worn-out gear or fixing crash damage, having this assembly on hand saves you downtime. The gears mesh smoothly with other components, and the pulley runs true without wobble. For the price, it's smart to keep a spare or two in your parts box since tail drive components do wear out over time. Definitely recommended if you need to get your Blade helicopter back in the air quickly and reliably.
