I am considering buying a Align T-REX 550E PRO DFC Combo and adding a Spektrum AR7200BX and wanted to see if there are any known land mines in this outfit. I got to fly one a bit the other day at our field, OK hovered it around but it felt great and seemed way more stable than my Trex 450 which I like a bunch. At our field the Align T-REX 550E PRO DFC Combo is well regarded but I wanted to check a bigger pool of possible owners to see if there are any hidden things to watch out for.
