Bind-N-Fly
From EFlightWiki
Bind-N-Fly or BNF kits are similar to Ready-to-Fly or RTF kits in that the airplane is entirely pre-assembled, but do not include a radio. The user can bind their DSM2 compatible 2.4GHz radio to the receiver in the aircraft, negating the need for an included radio. BNF models are usually cheaper than the identical RTF kit.
