I would imagine in the event of the uav looses comm during external pilot (EP) mode even in visual range, the uav will automatically track the preloaded flight plan (usually an overhead flight pattern) and if comm can't be regained the uav may either terminates, flies to comm hold then terminates, or performs and autoland

If the uav looses comm and gps during EP control then it will terminate immediately which mean a crash right in front of everyone usually

If the autopilot locks up then the above will also happen

So are you requiring the extra board to monitor comm heart beat and also provide back up RC control and manual termination?
