Version 4.0 software for the Align 3GX controller is now available from the Align website.
Probably the most important feature of this new version is that the 3GX will now support DSMx protocol when using DSMx satellites. Prior to this revision, the controller would only support DSM2 protocol, regardless of the protocol supported by the satellites.I have removed V4.0 SW from my 3GX installations as I believe the V4.0 SW has a serious flaw affecting control of the tail rotor servo and heading hold operation.
