RE: Mode 3 Radio?
i used to have a 9 vap futaba computer radio set on mode 4 from by futaba tectnitions
but the trims could not be changed to suit so i had to be content with them being crossed trimed witch is good in one way as you can trim say elevator with out haveing to take you finger of the stick the down side is when you try to teach someone else it complicates things so its nice to see futabas 12z can cater for all stick and trimm combernations
