They can easily mimic the damage on earth. While there is more gravity, we can adjust atmosphere and measure lift, vibration and whatever. Probably modern engineering tools can do this all in software, but cutting the blade off a drone on earth is easy. Only if we are convinced by on earth simulation that we can still fly this should we attempt it. Otherwise attempting flight this risks doing more damage to something else. (the rover is too far away, so I guess not much - but that also means we can't observe what happens and adjust based on the rovers sensors)
