Things like this have scratching my head about a DSMX module in one of my Futaba 9C's.. my DX-8 had worked perfectly, except physically it just isn't up to standards I was used to with only mid-range Futaba stuff. It just feels light and cheap, the gimbals don't impress me, tactile feel is like a bargain rental car. Recently a switch backed out and fell and jammed the throttle midway, but eventually I pointed it down and shook and it all came free. Oh and the elevator "up" trim is dead now, that's not overly convenient. Man I dunno.. DX-18, 20, what the heck..?
I love tiny, inexpensive and very reliable Spektrum compatible Rx's.
