I've been trying to setup a blade 450x with a 3GX unit on my new 10s. It needs transmitter mixing using HR3 (120 degree). All is fine, with the monitor showing the correct amount of servo movement until I reverse the ail and elev in the swashring menu. After doing that the mixing is lost, ie the monitor shows all servos moving equal amounts so that there is interaction between elevator and pitch when using the elevator stick.
Has anyone tried to set up a heli using FROS?
