✈️ RTF / ARF / BNF / PNP
The four common completion levels sold in the hobby, from a complete ready-to-fly package down to an airframe you finish yourself.
RTF includes everything including a transmitter; BNF includes a receiver you bind to a compatible radio you already own; PNP has motor, ESC and servos fitted but no receiver; ARF is the airframe and you supply all electronics. BNF only saves you money if your radio speaks the right protocol.
