It's a rounding displaying issue and won't affect your wpt position, we know about it.
Also, unfortunately Elmo had to take a step back from the Harrier dev, if you have any more questions don't hesitate to ask me.

Hah.
The Radio Control Set is not the control panel to a third radio, but the backup control to the radio sets in case of a failure of the UFC.
IRL, the UFC just doesn't fail.
In DCS the UFC failure is not simulated. The RCS can be set up but is not properly usable as a backup (switching the ACNIP to MAN will not make the radios use the RCS setup).
That can be arranged though, it is on the list but is fairly low priority.
