AfterBurner ESC is the first ESC we announced,
made to be used in either 30×30 or 20×20 quads,
capable of 50amp/channel or higher. Uses smaller fets,
and smaller components so will have the highest performance of any esc,
but needs external caps which are included,
and isn’t quite as durable as its larger ESC.
Uses smaller components which are less tolerant to abuse.
