Hey all, I ran into some trouble recently with a lock-out as a result of range problems with my AR6100 and totalled my plane. No big deal, gots to keep the spirits up and repair by next weekend for flying! But I did do a lot of research that established by consensus that the AR6100 is a medium-ranged receiver. Spektrum/Horizon Hobbies does not state a range for their receivers but instead use vocabulary such as "Park" or "Reliable" or "Full Range" to describe their line of 2.4ghz receivers.
