We found an article online from a pilot sharing his home-made landing gear. Let’s see!
The pilot placed the battery under his quad copter – as there is no extra space on the top of the quadcopter. However, the height of battery is longer than the original landing gear; thus the battery touches the ground first in every landing. The pilot assembled some bamboo chopsticks with cable ties to add some heights. It simply fixes the landing problem. The pilot suggests using carbon fiber booms next time for more powerful application.
