There's absolutely no way that Phantom, seen bouncing off the car's roof creating no damage to the car, is capable of carrying anything as heavy as that car battery seen smashing the roof and windshield.
I’ve run into the same problem in the past and have tested 24fps, 30fps and 60fps extensively. 60fps wins every time. The only issue I’ve found is that you loose some of that motion blur when flying at fast speeds close to the ground.
