ARF: almost ready to fly—usually needs radio equipment installed or minimal assembly. RTF: ready to fly—usually includes everything. Just unpack, charge the batteries, and go fly. BNF: bind and fly—a marketing term from Horizon Hobby describing ParkZone and E- flite models that come preassembled and ready to fly; all you have to do is bind them to a compatible 2.4 GHz radio. FBL: flybarless. The flybar imposes some gyroscopic stability to the rotor head. An FBL unit is a multi-axis gyro that replaces the flybar on the main rotor head. Instead of tinkering with paddle weight and mixing lever locations, you can change a slew of parameters with a software interface to the gyro unit. Many replace the tail gyro as well.
