ive been using the orange receivers for a little under a year now coupled with my spektrum dx6i tx , not had any problems with range , or loosing bind etc , of the 12 i have in use only one has failed , but that was due to it getting rather wet when my boat capsized ! ive seen the opaque orange transmitters , and there available through my source of receivers , but ive not used one , ive already got two spektrum a dx7s and a dx6i jon
