Question 1

What is the proper procedure for long-term storage of a Lithium Polymer (LiPo) battery?

Answer

Keep it constantly plugged into the charger

Question 2

Why does a multirotor drone typically have significantly shorter flight times at very high altitudes (e.g., 3,000m in the mountains)?

Accepted Answer

Because the air density is much lower, requiring the motors to spin much faster and consume more power to generate the same amount of aerodynamic lift

Answer

Because the GPS signal is too strong and overloads the processor

Answer

Because the air is too thick for the propellers to spin efficiently

Answer

Because the Earth's gravity is stronger at high altitudes
