Loading & PerformanceQuestion 81 of 100
A quadcopter has an empty airframe weight of 6.8 lbs. You plan to fly it with two batteries weighing 1.9 lbs each and a gimbal camera weighing 1.4 lbs. The manufacturer lists a maximum takeoff weight of 13.2 lbs. How much additional payload may you add?
a.0.6 lbs
b.1.2 lbs
c.2.6 lbs
d.3.1 lbs
Explanation
Count every item that leaves the ground: 6.8 + 1.9 + 1.9 + 1.4 = 12.0 lbs, which leaves 13.2 - 12.0 = 1.2 lbs of margin. The 2.6 lbs answer comes from forgetting the camera, and 3.1 lbs comes from counting only one battery. 0.6 lbs would apply only if the loaded aircraft already weighed 12.6 lbs.
