Ready to Fly Aircraft includes Radio, battery and charger.
Only minor assembly required to fly
ARF Aircraft are built and covered airframes, and will require Engine, Radio system, Electronics etc to be installed
KIT aircraft are completely unbuilt, and are generally supplied as a box of pre-cut wood pieces, a plan and instructions.
KIT aircraft cost roughly double that of an ARF or RTF airplane to complete, so these are normally purchased for the love and experience of seeing something you built from scratch take to the skies. - VERY rewarding!
Plug and Play (PNP) Aircraft have their Flight electronics pre-installed. To fly, simply add a receiver paired to your transmitter, install the battery (Charger required) and off you go!
