The rule of thumb is that the current load goes up as the head speed
goes up.

Changing low pitch won't make any difference. You must look at the
hovering pitch. To reduce head speed, you must increase hovering pitch
and correspondingly reduce hovering throttle.

Note that the T-rex 450 does not like a low head speed. It will start
wobbling if the head speed gets too low. There was a thread here a few
days ago about recommended head speeds.
