I too have Futaba transmitters - all on 72 MHz which I fly most of my glow stuff with. Within the last seven years I purchased a DX6i and one other Spektrum Tx - my only 2.4 GHz radios with no problems anywhere/anytime thus far. As others stated earlier, I also thought an owner was good to go with Spektrum so long as he/she used at least 6 Volts for airborne stuff to prevent brown-outs. This thread got my attention with a link to a recall that I either missed, dismissed, or don't even recall for the DX6i (2008?) w/ DSM2. I don't have the sticker in the battery area the recall pertains to and vaguely remember performing some test to see if cursors followed stick movement smoothly while in "monitor mode" without hesitation or segmenting. Is this what that recall was about? Thanks for any information in this regard.
