Remove the four screws holding each arm in place.
Turn IRIS over, and remove the bottom shell. You should be able to pull the
arms partially away from the body of IRIS.
Now you’ll need to disconnect the two plates by tearing the foam. Try to
separate the foam from the plate with the ESC as cleanly as possible at the
surface of that plate so there is minimal foam attached to the smaller plate.
Once the smaller, bottom plate is detached from the foam. Turn it over and
remove the four screws attaching the ESC to the plate. You should now be
able to remove the ESC and the arms entirely from the plate.
