This remind me of debug a flight control problem with my son's model airplane. We did a foam board stretch build of Model Airplane couple years ago. https://www.flitetest.com/articles/ft-guinea-build https://www.flitetest.com/articles/ft-guinea-build After we flew a few times, we added a servo to the cargo bay to be open and drop small parachute from it. After than, my son kept complained that he would loss control for 1-2 seconds while the plane is in the air from time to time. After research on the net, eventually I figure out it was the addition servo. Each servo in that air plane use about 1 Amp of current depend on condition. The 5th servo actually drew enough current that causes the remote receiver to reboot while the plane is in flight. That was a fun bug to figure out. The RC receiver is actually very good design which can be reboot and be operational in ~1 seconds.
