It comes with a high quality tail unit that is durable and precise. It features a 4mm tail output shaft and belt drive tail. The tail boom can be easily removed for maintenance without removing the main shaft. The Forza 450 has a pinion gear with one-way bearing. The front pulley has a large diameter, meaning there will be minimal belt slippage. This remote control helicopter requires a 3500Kv motor and a 50A ESC and a 3S-6S LiPo battery. You will also require a Flybarless control unit like JR's TAGS01, swash and tail servos, a receiver and suitable transmitter. Once complete, the Forza 450 offers unparelleled performance for the most ambitious 3D pilot. Order yours today.
