These are ARF's, not kits.. as most others, they come with what you order .. order the airframe, you get the airframe.
order the motor / ESC as well and you get those too
for the addiction I would recommend their motor, propeller, (although a wood 14X7 works nearly as well) and CF Vortex generators at minimum.
