title_body: ESCs for inverted flight? What types of brushless drone ESCs are reversible and will work for flying inverted?
upvoted_answer: ESCs loaded with recent versions of BLHeli (BLHELI_S and BLHELI_32) will support reversible motor direction, either through Dshot commands (obviously only supported when using Dshot signaling) or with zero-throttle centered around the middle throttle position, 1500µs (supports Oneshot/Multishot in addition to Dshot).
  
  These modes can be set up in the BLHELI Suite configurator.
