Our integrated cargo cabin has recently been upgraded, which becomes more convenient, more efficient, and safer.
The upgrade cargo cabin depends on the FC, instead of springs which were used to pull back the cabin cover after dropping the item, to send signals to a pair of servos and a pair of magnets to release, pull back and lock the cover after dropping, so that the disturbance caused by unlocked cabin cover flapping in the air is reduced and the flight is safer.
