So your claim is either that there is no gravity or that helicopters cannot fly. Since we see it happening damned near daily and many of us have actually flown in one, by or own experience you are proven wrong merely by the power of our experiences.
I've already explained to him why gravity is required for any winged aircraft to fly. He's a dishonest dipshit incapable of taking new information aboard, and he suffers blue balls, crabs, and diarrhea of the mouth.
