of course, i think most people use the gy401 gyro because of its performance but its the same size as the falcon gyro.....i use a gy401 in my falcon actually and if i ever upgrade ill put that into the new heli. if you plan on getting a falcon and later getting a nitro, might as well buy a new gyro for the nitro though so you can still fly the falcon, your going to have to buy new servos, motor, etc...might as well buy a new gyro and have two helis to fly
