As a engineer student, i have studied alot of physics, and i want to give feedback on the gravity system that pull the drone to a point in the center of the planet. thats not how things works. in our planet Earth, the gravity on the surface is approximately 9.8m / s², the gravity force gets weaker if you go under the surface. The deeper you go, the weaker is the gravity, until the center where it's null, it exist, but the resultant force is zero.
