I have experince with the Air Comm in the B407 - it was flawless in the time I owned it. When I spec'd this unit I asked a number of much more experinced B407 owners/pilots about which AC to buy and the overwhelming favorite was Air Comm. Given the great performance of the B407 the extra 60 lbs will matter only to some operators. I also have experience with other Par Avion products (but not the AC) and these have been superb as well.
