Product Information

Tracing its origins back to the highly popular Blade Fusion 480 and stretch kit, the Blade Fusion 550 improves upon two decades of development and engineering experience to bring you a high-performing and high-quality RC helicopter that is reliable and tough with the capabilities to deliver anything from basic hovers right through to 3D aerobatics. 

The speed at which the Blade Fusion 550 can be assembled is due to the advanced airframe design which includes highly toughened but lightweight aluminium and carbon fibre components. The design also makes this RC Heli easy to repair and maintain. Precise and responsive control is provided by the optimized servo geometry which facilitates a wide array of flying capabilities. A 10-pole 4320-1180Kv brushless outrunner motor is included to drive the quiet helical main gear which delivers high performance and incredible torque when paired with popular 4000-5000mAh 6S LiPo's. The construction of the belt-driven tail assembly also features aluminium and carbon fibre giving you a locked-in tail performance every time you get airborne.  

Whether you're an intermediate pilot embarking on constructing your first kit-built RC Heli, or, a highly experienced 3D chopper jockey, the Blade Fusion 550 combines capabilities, value, quality and convenience with enough flying capabilities to keep everyone happy!
