Yes, you can. Three things to keep in mind. First, you probably won't get 120+ FPS from the stock flywheels. You need flywheels with more "bite" when the motors are at the stock 43.5mm crush. The smooth stock flywheels will accumulate some dart burn and work better over time. But it probably won't get much more than 105 FPS. If that.

The stock cage will also work. For a while. The tork from the motors will start to weaken the plastic over time. Every time you pull the trigger, the tork will bend and twist the cage. Eventually it might crack the plastic. That's why replacement cages are either metal, or thick high density Delrin (POM) or PLA.

Lastly, the rubber straps that hold the motors in the stock flywheel cage might not be sufficient. Fangs are meant to be screw mounted. They should even come with screws. If you know someone with good machining skills, you can make countersink holes in the stock cage so that you can screw mount AND use the rubber straps.

My advice is try it for a while, save your money, and replace the flywheels and cage some time in the future.
