RE: Is it an ARF or not? Define ARF
And as hgiles said: All of the necessary components to complete and fly the model are included in an ARF kit, except the radio and engine.
Included: Engine mount, fuel tank, landing gear (including retracts) wheels, pushrods or control cables, control horns, clevises and ALL of the hardware required. (It may be junk, but it's all there.)
Not included: Engine, muffler, fuel lines, propeller, spinner (sometimes), servos, servo arms, extensions, receiver, switch and battery.
No finishing is required of an ARF other than the application of trim stickers.
