I Changed to futaba some days ago after having problems with Spektrum which are already discussed.I put the 6ex Module into my Royal Evo9, so i have 7 Channels.
I will use it until Futaba offers Modules for MPX.
Its a bad Status for Futaba, this heat Problem, after the problems with the 6ex and ff7 (missing code numbers)
but i hope they get the problems under control, especially in larger and more expensive planes it would not be good to have a receiver making evening when sun comes out
