How should i place the antennas on the remote controller for best signal strenght, relative to the aircraft? What does RTH altitude mean? Meters above the ocean, meters above the point from which it took off? Isn´t it always best to hand catch drone when landing, since there often is grass or small particles that can get inside i i land on the ground? What is the fastest way to return to startingpoint, (presuming you can get the right direction manually), RTH, sport mode, other?
