H frame vs x frame

Greetings
Just have a question out of curiosity.
What is the difference as far as arducopter is concerned between x and h quads? It seems to me that since the motors are in the same relation to each other they would have the same control requirements

uh-oh , you asked that taboo question ! Tell us if you ever live to know :slight_smile:

Could it be that more torque is needed for pitch than roll?

if it handles asymetric frames, yes, maybe even separate roll/pitch PIDs
