ALT circuit breaker
Toggles One Wheel under the right wing (Adds 29lbs to the payload).

The latch at the bottom of the door on either side of the cockpit will open the doors. They are affected by wind so don't leave them open at high speed! (https://parallel42.freshdesk.com/a/solutions/articles/44002323558)
