ARF, BNF, PNP, RTF - What Does It All Mean??

Posted by Motion RC on |

  • Category: Beginner Guides
  • Motion RC aircraft are available in a variety of Product Formats to suit your needs. The Product Format and its three letter acronym, are a basic designation which tells you two primary things, 1) what amount of assembly is required and 2) what is included with the model. The following table provides a brief summary of each Product Format. More detailed descriptions are listed below the table.

    - ARF stands for "Almost Ready to Fly." An ARF simply means an aircraft that requires your own choice of electronics to install in the airframe.  Most ARF's require you to purchase all of the electronics 
    separately (motor, servos, ESC, and sometimes additional accessories).  ARFs are a cost effective solution for hobbyists who either prefer a true build process and/or prefer to put their own choice of electronics in the aircraft.

    ARF BUNDLE - An ARF Bundle is an ARF model bundled with all the electronics you need to build the plane. These bundles typically include servos, motors, and ESCs. The bundle simplifies your purchase and saves you money compared to purchasing the required electronics separately. 

    ARF PLUS - Expanding on the standard ARF format above, the ARF Plus model has all electronic components pre-installed, except for the power system (the power system includes motor, EDF unit, and ESC/UBEC). All other components, from the retracts to the servos to the lights, are factory installed. ARF Plus models are near ready-to-fly aircraft that give pilots the option of experimenting with custom power systems.

    BNF - BNF or Bind N' Fly airplanes/quads/helicopters include a Spektrum receiver pre-installed from the factory. You must have a compatible Spektrum radio (sold separately) in order to "bind" to a BNF aircraft. BNF models do require some assembly, typically 1-2 hours of build time. Most BNF models do not include a battery or transmitter.  

    KIT - KIT only applies to our helicopter models and describes a product which requires full assembly. Most advanced helicopters come in KIT format due to their complex construction.

    KIT COMBO - A KIT COMBO is a helicopter kit that also includes the main electronics. These combos typically include servos, ESC, and motor. 

    PNP - PNP or Plug N' Play products are near ready-to-fly models requiring typically less than 1-2 hours of build time. PNP models include all power systems and flight control electronics pre-installed from the factory. PNP models do not include a receiver, battery, or transmitter. 

    RTF - RTF means "Ready to Fly."  Airplanes that are RTF come with everything you need to fly. A transmitter, battery, charger and receiver are all included in the box. All you need to do is charge your battery, attached the wings and stabilizers (in some cases these are pre-attached) and you're ready for flight.

    RxR - RxR is a Hobbico proprietary term which means "Receiver Ready" and is identical to PNP.

    TxR - TxR is a Hobbico proprietary term and means "Transmitter Ready".  TxR is similar to BNF, however, refers to a series of aircraft developed by Hobbico that work with any Tactic, Hitec or SLT radio and comes with an SLT receiver.  If you wish to fly TxR with a non-compatible radio (like Spektrum as an example) you can either remove the SLT receiver that comes with the aircraft and put your own compatible receiver in, or you can purchase the AnyLink 2 radio adapter that allows your radio to communicate with the SLT receiver.
