Heli-phile:
IMHO, the Enstrom 480B is an impressive acft. See my posts in the Enstrom Corner section of Rotorheads for more details.

I am new to this acft and havent yet looked closely at the temp in cruise except to note that is is about "mid green." (I have made only two flights since delivery.) Will check this on the next flight.
407TX has provided a copy of the Bell Information Letter referenced in an earlier post. THis is very helpful to understanding what is happening. It looks like one click of the "tweaker" CW should improve accelereation through the 40% to 60% N1 zone.
