Difference between 22/20/4 and 22/20/4H

What is the difference with the Helicopter version of this motor? I just tried to make a deal on a 22/20/4 and relized that Mega makes a special H version. Should I try to kill the deal or is the standard version ok. They look to have the same IO numbers

Other motors with an "H" code have cooling fins or/and internal fans. I would bet that is the diff., but that is just a guess.
