So, M5P with large batteries >249g you should have TRUST certificate, FAA registration and the number displayed on the M5P? As I understand it if the M5P has the larger battery installed it will broadcast RID when in flight...?
Yes, take the TRUST (you can take that test today, no need to wait) and register with the FAA. And....I think there might be one other item you need to complete, not sure.
