Description

Using Copter latest and MP beta, it seems like there's a new "Prearm check failed" message appearing on the HUD. The problem with this is that it hides the underlying pre-arm failures which can be seen in the screen shot above by looking in the Messages tab

Research direction
Reproduce the issue with Copter latest and Mission Planner beta, then compare the HUD with the Messages tab shown in the report. Trace where the generic "Prearm check failed" HUD message is produced; done means the underlying pre-arm failures are visible on the HUD instead of being hidden.
